Hello and welcome to the live stream today. We are talking about the new firmware update that has just dropped for The Rocaster Pro 2 in fact there have been two of them that have come out in this last week The first one was one dot one dot one and then also the funnily enough one dot one dot two has just come out a couple of days ago with a couple of minor fixes, I believe so this is basically a Major release of the beaters one dot o dot eight o nine and one dot one dot So if you have been on the beta program, then there's not really going to be anything new in this But if you haven't been on the beta, then this has got quite a substantial update namely This concept of submixes. So what I'm going to do today is I'm going to talk about the Submixes in particular and what they are and why you might need them or if you even need them If you want to know what all the fuss is about and then I'll also talk talk about some of the other updates That there have been as well. There's been a couple in fact one major one I would say to the road central app Which has added a lot more functionality to that and given you basically full control over the ROCASTER Whereas before there were some things that you wouldn't you weren't able to actually control or set In the road central app. So that's what we're going to be talking about today So first of all then when we are talking about submixes This is kind of building on an extension of the ability that we had on the USB channels. So bear in mind on the ROCASTER Pro 2 There are two USB cables coming out the back of it for data There's also obviously the usbc charge power power cable as well But of those two usb cables There are basically three channels on the rcp2 one of them is called ROCASTER Pro 2 main One of them is ROCASTER Pro 2 chat. Those are both on the first cable and then there's also ROCASTER Pro 2 secondary Incidentally, I saw on one of the ROCASTER videos Sorry, one of the road videos, I should say that they were talking about potentially in future updates adding in additional Virtual channels. So presumably those would also be over usb But it would give us extra channels to work with when we are looking at doing audio routing So for example at the moment, I have my e-cam live Which is the program I use to make all of my videos and for virtual camera and so on into zoom, etc So that is on my main channel. Then I use chat for discord So I've got my discord back channel going by the way, if you want to join the discord back channel Live during these live streams check out my membership down below But that's basically on my chat channel. And then I have zoom on my secondary And my system audio I've got a workaround where I bring that into the back of the ROCASTER actually taking the headphones out of my Headphone socket output from my Mac and then I take that into a stereo pair into two of the connections on the back of the ROCASTER And that basically gives me a fourth channel from the computer So what they're talking about introducing then is more virtual channels So presumably they would also pass over usb And then I would have all of that control rather than having to use up that stereo pair But anyway, I digress it's just interesting to see that they are listening to Users and looking to add features and functionalities and certainly these sub mixes Was something that was sort of community driven in terms of lots of people asking for it So enough of that waffling. Let me get on to exactly what it is And what I'll do is I'll come into my top down shot here And you're going to find this basically in the settings Then in the outputs and then in rooting Now just to explain a little bit previously What we had was in the as of the the previous Version of the firmware the major release of the firmware We had the ability to for each of these particular Channels to choose between either the mix minus Or on or off and that's that's the sort of limited of what we had In terms of the the sort of rooting there was also this custom rooting as well And that allowed us to choose which particular channels were going out to which particular input channels We're going to which particular outputs. So let me just step back for a moment and kind of explain what this is all doing If you think of the Rocaster as effectively a an audio hub, you've got a series of inputs, which would be the four microphone inputs or line inputs at the back And then you've also got those usb channels that we talked about the three usb channels And you've also potentially got bluetooth coming in as well And maybe even actually an ipad or an iphone or something coming in over usb as well So you've got all of those things that are feeding audio into the Rocaster Then you've got all of the ways that you can feed audio out of the Rocaster and that would be For example the the speaker monitors at the back And then you've also got all of the four headphone sockets at the back as well And then you've got those usb channels going back out as well and obviously bluetooth passing out as well So everything can come into the Rocaster and everything can come out So the kind of default thing that you would have on the Rocaster The default out-of-the-box settings as it were would be that everything that comes in Can be heard by all of those outputs and as you adjust the faders on the device You are adjusting basically the level of that that Audio going out to all of those different channels So the first setting then that you have here with mix minus Just to explain what that is specifically is if you've got a A particular channel that you're using for audio for example with zoom I mentioned that I use zoom on one particular channel Well, you've got audio that's coming in from zoom into the Rocaster But you wouldn't necessarily want that audio to be fed straight back out to the Rocaster as well Because then you would have the sorry out to zoom as well because you would have the people on zoom talking That would be coming into the Rocaster and then it would be feeding straight back out to them And they would hear a sort of repeat of themself coming back And a lot of people refer to that as echo technically slap back But whatever the case you don't want that sort of audio going back out the way it came And so mix minus basically Says that right well anything that's coming in from the zoom channel I'm going to remove from the audio that's going back So therefore that particular channel that you might be using for zoom Is going to hear all of the other audio so the microphone any sound effects anything coming in from any of those other channels But it's just going to remove that that slap back basically So mix minus is removing the thing coming in from the mix it's minusing from the mix And so that is why it's called mix minus There are instances though where you may want more finding control. Let's say for example You've also got your system audio coming in to just keep with a zoom Analogy perhaps you don't want any of your system audio sort of bleeding through into zoom as well So what they had in the previous version was this idea of custom routing And what that gave you was the ability to just completely exclude certain Channels input channels from the output to that particular channel So in that sense what I could have done previously was Hit that custom and then I could change the the zoom channel the channel that I'm using for zoom I could simulate the mix minus by removing itself from that output But then I could also eliminate any other channel that I wanted from that output as well So this is basically what they're building on with submixes because now if I click on custom now Rather than just simple toggles for each of these channels What I actually have the ability to do is adjust the level Now I can still do exactly the same as I was talking about so if I just go over to the channel that I do tend to use for zoom I can still completely Mute anything from here But what I can also do and if I just zoom in a little bit what I can also do is I can set independent levels so what you can see on here is Basically, this is currently representing exactly what I've got on the sort of main board down below So you can see here these different channels are at these different levels And if I go back to this view you can see that these are roughly the same But what I could do is let's say for example this mic for input If I wanted to actually say right well, I don't want that coming through into the mix on my side But I would like to just actually put that up more into into zoom That would be the way that I would do it I can click on any one of these and you can see that I am adjusting this and it's adjusting the level Of the mix just for that particular output And here you can see the output is rocaster pro 2 secondary Um, so that's kind of the way that this works is you can adjust these levels But one thing you'll also notice is uh, there's this blue bar just underneath it You may not be able to see the color exactly but there's this kind of blue bar, which is where I've moved it from So if I look at the main board Once again, you can see that here and we're looking at this particular channel here. It's right down at the bottom Whereas here, um, I've now moved it up But there is that blue bar and that's because the blue bar is to signify that these two things are still actually linked together And so by the way the way that you adjust these these levels is by just simply tapping on them And then you use the rotary dial to adjust it. So if I tap back on this one You can see that that's how i'm adjusting it But if I move it up to here, um, actually that blue bar signifies that they are linked And in fact the little icon down at the bottom here, you can see this little sort chain icon That shows that this is still linked to the fader And so if I come back here and I move the fader What you can see is that both of those things are moving the position of the fader is moving But also the position of the um, the new level that we've set in the for that particular channel So this is basically relative. It's going to be just moving relative to the actual position of the fader Um, obviously there is a point where this could be completely maxed out Um for the the new setting. So if I was to just keep pushing the fader Basically, it's just going to sort of close that gap down Um, and then as I move the fader back down again It'll open that gap up to maintain that sort of spacing between if that's hopefully making sense Um, so if I um, then go back to here You can see as I move the fader. I'm just moving the fader. You can hopefully see a bit more of the effect Obviously, there's a point where both of them become maxed out But if I move the fader down again, it's going to open up that gap and then bring it all the way down So that is with them linked But you can actually just unlink them if you want to set a specific level for a specific channel And not have it affected by the fader Maybe I just permanently want that to be set to that level And as soon as I click the little link icon Then now you can see that as I move the fader the little faint white fader line is showing the position of it But it's having no impact whatsoever on this level that I've set for this particular channel So I'll come back to here and as I say you can see that as I move in this fader It's not actually affecting this channel whatsoever Um, so that is that and if you press it once again that little link icon You can see that that has now actually completely eliminated it So it's gone dark there and if you look at the the icon here It's got a little cross next to it. So those are the three basically Modes for that either it's going to be linked to the original fader position Or it's going to be unlinked and you can do what you want Or you can Click like that and actually exclude it from the mix and by the way since we are here adjusting the Rocaster Pro 2 secondary and I've already mentioned that this is the channel that I use for zoom And I've already said that mix minus is going to remove that channel from, you know, the incoming channel from the upcoming channel When you want to simulate mix minus yourself, basically what you would be doing is you'd always just be removing That particular channel. So here Rocaster Pro 2, sorry the secondary Rocaster Pro 2 secondary And if I click this to completely remove it like that, that is now removed from the outgoing So this is basically simulating a mix minus So if you you're you're basically making a choice between either it's mix minus or it is custom or obviously the main mix Which is just going to be unaffected completely But if you are on custom Just remember that you will need to sort of manually create the mix minus if you need that if it's basically a communication app And to understand whether you actually need mix minus or not on any particular channel It's essentially that it's wherever you have got basically two-way audio going back and forth to a particular You know communication app So I have mix minus on my Ecam live channel for recording because sometimes I use interview mode I've got people coming in and then I want to be able to record them But I don't want them to hear themselves back and so on So that would be one instance Discord Skype Do people still use Skype? Microsoft Teams And zoom and so on so all of those communication apps You're basically going to want to have mix minus on to be honest as a rule of thumb I would say that for most people most use cases on a computer You're probably better off switching it on because there's few cases where it's going to be a problem If you have got it on where there's lots of cases where there's going to be a problem if If you haven't got it on so I would just always recommend you might as well just switch that on for that for that case And so that is the the way that this works. I don't hope that is all clear I'll just say a quick hello. I've been neglecting the chat. Hey Richard. Great to see you here. Thank you for stopping by Let me move that out of the way. It's always the same first comment I put up. It's always in completely the wrong position So What can I elaborate on why another channel for discord if already live with the feed? So what I if you're talking about what I mentioned about having the the backstage area in In discord what I do with that is I have my members my backstage pass Members we get together in discord. First of all before I start the stream I'm feeding my ecum live output directly into discord in any case Using the virtual cam feature. So we have a little hangout in it's a bit like a zoom call really In terms of the the functionality of they're called voice channels in discord But it's actually video So we can have a little chat there before before we go live And then when we finish the live stream, then we just have a little hangout and a geek out about All things tech after the fact. So that's why I go live into my YouTube but also into discord as well If that is what you are talking about if you're talking about specifically another Roadcaster channel, then it's just to keep all of those things separately separate. So anytime you've got communication apps On your roadcaster for example if you're using ecum live or maybe obs or anything like that where you are using the The communication functions of them and they are going into a separate communication app like zoom I want to make sure that those two Audio tracks are completely separate and that's a good point to to make really is when you are thinking about how To sort of set up your roadcaster with different apps If you've got anything that requires two-way audio as we've mentioned You want to have that mix minus on if I was to have my ecum live and my roka and my zoom on the same channel um I would need mix minus on for the benefit of zoom and also if I was using interview mode in ecum But then the problem would be that it would also remove the zoom audio from going into ecum And it would also remove the ecum audio from going into into zoom. So that's why I always recommend having each individual Like communication style app that you might be using at any given time simultaneously have those on separate channels So for example, I've got a separate channel for ecum for Discord and for zoom because there are times when I use all three of those at the same time I never use teams and zoom at the same time So I have microsoft teams on the same channel as I have for zoom because I know that those two are never going to be open And used sort of simultaneously And that's also by the way why I send separate out the system audio Because I want to have sort of full independent control over that and can decide Actually where it's going to and the the level of it and so on. So that is why I I do that And uh, oh, thank you very much. I appreciate it. I'm glad you find everything get useful Hey, paul. Great to you here as well And rebel without a reason. Can you root the effects button voice disguise to other channels for callings? Ah, that's interesting. I don't think you can root the um the voice effects specifically to channels But what has changed now is in multitrack previously When you choose between pre fader or after fader Let me step back a bit or pre effects or after effects the The pre fader is basically with multitrack recording on the on the rocaster You can either record multiple all the tracks individual multitrack to the device You can also send that all out to your computer as well if you've got a piece of software that you're using Like Adobe audition or things like that. Um, that's can that that can actually see all the individual tracks That would always go out over the uh, rocaster pro 2 main In fact, let's just have a quick look at that because uh, it's worth with diving into this a little bit more If I go into the outputs And then it is in uh, multitrack So for recording, um, you have the option to record The multitrack on the device and so the options you've got here are either it's going to be off So it's just going to record a single file to the device If you want to have it record every file individually and what that means is basically At the end of it, you're going to when you look on your sd card We can look at how to do that in road central as well When you've recorded something using the record button here If you've got this set to off, you're just going to get one file, which is the main mix However, if you have got this set to prefader, what that's going to do is it's going to give you every single audio track of audio that's been coming into the rocaster But prefader so that means that anything that I've set here in terms of levels are going to have no bearing on it It's just going to take the raw signal coming in and usually that's likely what you want because the The way that you are going to potentially want to work with this Is that you're going to want to take the audio from here and then do some post processing with it in some other app However, maybe not. Maybe you actually Want to have it after all of the effects have been applied And so here there's an option here as well to bypass process processing completely So the way that I have this setup is I want it prefader I don't want to have adjusted the sort of gain if you like on any of these with these the faders But I don't bypass bypass the processing because I do want all of the audio processing from my microphone to be included So that's why I have this one unchecked But you could also have post fader and in that case if you were to be fading, you know A particular guest up and down or something like that Then it would it would also come through onto that particular track of that that audio for that channel What they changed in this version though. Oh, and by the way, you've got the same with usb So with usb the options for the Rocaster pro 2 main Channel is it's either going to be off in which case you'll see it to show up as rocaster pro 2 main brackets stereo And if you've got any of these set either prefader or post fader That's going to change over to rocaster pro 2 main multitrack So that's just a good way of checking to see if it's on or off If you're not using multitrack and you know that you aren't you know bringing in multiple tracks into your computer Into a particular dedicated piece of software I'd always recommend turning that off Um, there have been instances of you know It not sort of playing nicely with certain apps when it's sending a multitrack signal when Your app might be expecting just a regular sort of stereo signal So don't switch that on unless you know that you need it basically Um, but just to come back circle back around to your question about the effects Um, you can't sort of apply the effects to a specific channel and say right Well, my audio is going to have voice disguise But only going through to that other particular channel But what does happen now is previously the voice effects wouldn't come through on these these multitrack mixes Um, so even with the uh, you know post fader and processing enabled You still wouldn't get those voice effects. So that's one thing that they have changed now Is that those voice effects do pass through but yeah, you can't do that individually at the moment Um, and let me see what else I've got down here. Hey parker great to see you as well And hey michael great to see you too um, so that was um, that was the submixes so When are you going to use them and what are the the limitations of them? Well, one major thing that I can see as a potential issue with this is you've got to really know what you are setting and where you are Creating these settings because it might be, you know, nice to think oh, I'm going to adjust the level Somewhere, let's just take an example of this then If I come back into my settings for a second and I'll go to rooting and let's just stick with that particular channel Oh, and by the way, uh, one of the main things that's happened now is obviously previously That thing of audio rooting where you could decide which channels go to where you know, which are included in the output It did only used to apply Um to the bluetooth the usb channels Um, but not actually specifically the recording the recording was always the main mix Um, whereas now we've also got the recording We've also got those monitors and we've also got the headphones as well So if I go to one of these headphones Currently, it's set to main mix That was something that came in the very last update. I think it was just always too custom But now you can just have obviously to this secondary headphones here I've got the main mix, but I could actually have that as custom and just have certain things set out there There's a number of ways that you can use this obviously These are for are intended for, you know, you've got four mic inputs You've got four headphone outputs the rocaster was built for podcasting You can imagine a scenario where you've got four people sitting around the table They've all got a mic and they've all got a headphone and you can therefore adjust the levels What I've actually done is I mentioned before that little Way that I'm bringing in that fourth channel. So that's actually here. This is my stereo pair coming into my computer What I've also been able to do then is Take a headphone output as well to give me a as well as a fourth Input into the device. I've effectively got a fourth output So that can also go into my computer and my computer would then see that coming out of the headphones as a mic And then that gives me that extra complete fourth channel into there as well But I digress I'm probably getting overly complicated and for if unnecessary for this particular Livestream, maybe I'll explain that one in a separate video. But for the time being though Yes, we can actually control these levels in to certain of these headphone sockets There's lots of reasons why you may may want to do that as well But the issue that I just want to highlight with this if and it's not it's not an issue in terms of Functionality, it's more of an issue in terms of usability and you need to know exactly what you're doing with this Let's just say for example, I was going to I'll just move this slide up here. This fade it up So this channel for this mic for Let's just imagine that we've got this here at it's actually a unity level just to put the that level there So imagine now that I say, okay. Well, maybe in zoom. I want this a little bit quieter So I'm going to tap into here I'm going to move this dial down so that now it's it's lower So what you can see is the the actual level of the fader is there at unity Whereas this fader is now lower on the just that going out to this zoom channel The rocaster pro 2 secondary we've made that lower. Okay, but the people in zoom can still hear it But what happens if we move the fader down because bear in mind when you are actually, you know using the rocaster You're not going to have this open for every single channel to be able to see it And so what that means is if I move this fader down on my The the main fader there's going to come a point where just about here What happens now is for me The fader is here. I can still hear it But actually if I go and have a look at what's happening with that zoom channel, we've already hit bottom So actually by moving this fader down It's now not going into zoom at all Into the rocaster pro 2 secondary But it is still coming into my earphone So I might think that I've just turned it down a little bit But in actual fact for the participants in my zoom call, then it will have gone down off altogether So this is the the potential issue that I see with this With having so many controls Obviously, it's great to have this for people who want to use it and know what they You know know how they're using it and are aware of all of these levels But what would be really great and I've put this in as a feature request would be if there was some sort of visual On the main screen. So if I came over to the main screen here Obviously, you can see the actual levels We can't go and put, you know Eight different levels or nine different levels because bear in mind we've got In fact, how many is it? I think it's I think it's technically 10, isn't it? If I go back into outputs and rooting Yeah, we've basically got 10 different channels Which means that we could have 10 different levels Of audio and in actual fact there is this level as well, which we could change So we've effectively got 10 11 different levels for each channel It can be quite complicated to keep track of can't it if you think about it And so whilst it would be good to have some sort of indicator on here What I think would be useful is as well as showing the actual position So as I move this fader You see this move here It'd be really great if we had one that sort of measured like well What is the absolute minimum level that we've got across all channels? And what is the absolute maximum level that we've got across all channels? Because then you would just have a visual to be able to see that right Well on one of the channels whichever that may be and you would obviously be aware of that As I'm moving this fader down one of these is going to zero potentially Just like that example I showed in here Where was it there? So yeah, that is just something to be aware of I'm just on the wrong one. There we go this one So that's just something to be aware of with this that when you are setting these levels You've got to maintain in your head where they are all are relative to each other And the other thing would be if you are switching between apps or you're maybe Switching up which particular channel you're using for which so maybe you've previously been using the secondary channel for your Zoom communication apps or whatever it was and then you are switching over to another one You'd have to just make sure you go through and adjust all of those settings again So that's where I see a potential for For confusion with this in terms of not sort of remembering or recalling Which which levels were set to what the other thing to bear in mind with this is it isn't really that easy to just make changes on the Fly with this So one thing that I do with my rocaster Basically all of my levels I'm not using submixes just to be clear about this the way that I'm doing this is that I use the the the monitor buttons on the mute buttons down here For example right now what you can see on my rocaster is that these channels here are all actually muted For the stream so you're not hearing my discord. There's nobody in my zoom channel as it happens at the moment But you're basically not hearing that even though you can see the volume level there The if the the people in the back channel were having a party as they always do That's not going to come through to the To the live stream and neither are any of these because I'm using this mute button The mute buttons down at the bottom But what I'm doing to be able to still monitor those is I use these listen buttons that are just down here So basically the listen button means that you as the host on channel one You're going to basically be able to Listen and isolate any single one of these tracks or channels And you'll be able to monitor that even if it is on mute But you can actually monitor multiple channels So you can see that basically I'm using the listen button on all of these channels so that I can hear them all But then I'm just muting the ones that I don't want to go out in the stream And in this way, I'm still able to hear what's going on in the sort of back channel And I can still move the volume up and down on that for me using the fader So I've just sort of moved that down a little bit. So the raucous rat crowd I'm not Coming in my ear too much with that But crucially it's not coming out into the stream. So that is the way that I I do this And as I say, I'm not actually using the the submix functionality I'd rather just be able to know at all times, you know, be able to hear these levels and either include it or exclude it But I'm sure there are people with other use cases that will find The the audio routing and specifically the submixes Really useful, but I just wanted to make that clear that they're not for everybody and they do introduce Let's just say they do introduce another potential failure point. So it's great for those who need it But you might not actually need it Um and uh, Richard use the audio routing a lot. I like it I just wish they had a toggle to include the mic effects on all faders Um Oh, yes, I see what you're saying. So yeah, the the mic effects currently are only available on some channels They can't do it for sort of incoming calls, for example and and things like that. So I get what you're saying Um You hate headphones and rely on your monitor speakers Only way I know of hearing my voice effects is to use cable from Headphone out to a fader in and keep the fader below feedback. Uh, oh hang on. Let me think I've got to I've got to just read that again um Do you to hear your voice effects is to use a cable from a headphone out? Oh, that's interesting. So I get you so you're feeding your your from one of the headphones That's going back into the roadcaster And then you're uh hearing it that way Hmm So on the um on the monitors, I thought that they came through on the monitors actually So went to the voice effects are not currently coming through on the monitor speakers Is that what you're saying? I always thought that they uh would come through. I don't use monitors myself So I didn't actually check that but I thought that the monitors would be the program out And so you would actually hear it Um because if if there's a case of you're not hearing it because your speaker volume is Your mic volume is up Um, then there is a setting in here. Uh, this might not be what you're talking about But just in case um on the uh the outputs and if you go to monitors There is a thing that auto mutes the monitors when you are speaking. So if you've got your fader up Um, so you can toggle that one off and then it would just come through all the time Um, but so you're saying that the uh the audio effects are not coming through Hmm Um, I don't know but that's I love that. I love that creative solution though I've taken an output and putting it straight back in again. That's that's very cool Um, I can't think of a better way to do that if it's not coming out. I'll mix minus on the monitor out mix my So the mix minus shouldn't have uh, I get what you're saying Because of that you're you're talking about the feedback coming in from the monitors perhaps But mix minus technically there isn't a mix minus on Yeah, you wouldn't have a mix minus on your own Um On your mic mix minus basically is what's coming in on that channel is removed from what's going out So there isn't mix minus on the monitors, but I kind of get what you're saying I'm not sure I can think of a better way of doing that with the effects I'll have to I'll have to think about that and I'll play around with it And I'll maybe drop something in the discord and uh, um I'll have to think about that. Yeah, um, I mean that yeah that's so the feedback I get that the the feedback you're getting would be just because it's coming from It's coming from the monitors But that's why they have that that option there to to mute the monitor when you're speaking because you obviously don't want to have that coming through um Yeah, there's no way to avoid that you wouldn't be able to have mix minus because anything you're removing from that Um would also be removing it from the signal going out Uh, yeah, I'm I'm I'm at a loss for that one actually I've gone out there. I kind of get the problem though It's like you want to be able to include it in the monitors But then then remove that from the feedback from going out into the mix. I guess that they're not doing that because You know it from a from an audio perspective you would have You know, they would always recommend use headphones and in a in a professional studio You wouldn't have the monitors coming through while you'd got a live mic So to try and then remove it you're doing a lot of heavy processing Then if you're trying to just remove the feedback you're doing a lot of heavy processing on the signal that's going back out It would be a great feature request though because you never know I mean, obviously there is a use case you are a user and you've got a request for a feature So definitely submit that as a feature request There was one that I submitted actually on behalf of someone in the rocaster in in my discord server That was asking for audio processing now that the rocaster pro 2's got all of this audio processing capability The request was for background noise cancellation Obviously there's a lot that you can do with Audio on the rocaster in terms of adjusting, you know noise gates and things like that But since it has got such a powerful processor, you know having something a bit like crisp.ai the the Service that allows you to remove background noise. I used Previously audio hijacked before using the rocaster and that I could use that to sort of remove any background noise So having some of that on board processing would be great as well. So I have submitted that as a feature request. It's not technically a You know production studio thing because they would just say well, I just the audio issues at source rather than trying Remove them with processing afterwards, but yeah, it's good to It's good to be able to just put these things in because obviously it's a consumer device I'm sure there'll be people who'd find these kind of things are useful Um So rich is saying in the mean, I mean the same mic effect on all faders rather than separate Oh, I got you. So for the um, uh, yeah coming back to this So basically just being able to apply the effect but to everything rather than just the individual Uh things I get you. Yeah, I don't think you can do that at the moment either Because they are applied to individual individual channels Um Interesting feature requests though I can see a we're building a list of feature requests and definitely get those in because They they they are listening obviously they're putting in these features that people are requesting Um, incidentally, uh, these new features will be added to my uh, Rocaster Pro 2 masterclass So if you haven't checked it out already, uh, I'll leave a link in the I'll have left a link in the description And I'll drop one in the chat right now, uh, but this is basically over 100 videos that teach everything about the Rocaster from, you know, getting it out of the box and setting it up All the way to some of the more advanced things you can do with the audio routing and and actually using some of those advanced Audio processing. Uh, so on the consultation calls I have with people Once the Rocaster came out. I was having quite a lot with people on the uh related to Rocaster and specifically setting up their audio because It's such a powerful piece of equipment the Rocaster Pro 2 But actually people can sort of get themselves in a bit of trouble with it where They've maybe not got their advanced audio settings. They're using some of the advanced audio But then things like the noise gate Compression and things like that when people start diving into those There's lots of terms that people aren't come, you know familiar with so, you know compressors What does a compressor do? Threshold compression ratio gain attack and release. What do all these terms mean? There's all these little dials that we can turn and I think a lot of people get into a little bit of Uh trouble because they're not quite sure what all of these things do and so they kind of like flying blind as it were Trying to make adjustments to improve their sound But not understanding what it is they are doing. So this is where Really why I created the Rocaster Pro 2 masterclass was to cover all of this, you know advanced audio processing stuff So if you really want to dive into all of this Understanding, you know what our high-pass filters ds and all these kind of things As I say over a hundred videos covering all of this kind of stuff It just keeps going on talking about signal change. So that's the other one by the way Needing to understand a signal chain if you are making changes to settings, which order should you do this in?  So you've got these different steps here these different audio processing You basically want to go through in order So first of all set the gain level on your mic using this to get the gain level right And then you would just click into the first one here high-pass filter and then just hit these little arrows So whenever you're setting this up It's a good idea to sort of toggle them off and go through these one by one and set them up that way because Otherwise if you're making changes to Right down here to the exciter the big bottom Bunniest name of any processor in the world and the aural exciter if you are making changes to this This is affecting the low end tones or the low end of the frequency spectrum However, if you were then to go back down here To the high-pass filter and knock out all of the lower ends of the spectrum You've just completely, you know affected that thing that is supposed to be a later change So that is my little top tip for the day is go through these processing Steps one by one from the from the output from the beginning here Then you've also got the master compiler, which is basically Applying things like compression to all of the mixes all of the tracks as a single mix. I should say So make sure you do go through and do those in order But anyway, all of this is the sort of thing that I cover in the ROCASTER PRO 2 master class And this new update will just slot right into the audio routing section that we've got in there And I'll be making that video very shortly. So that is the ROCASTER PRO 2 master class I obviously I highly recommend it if you want to become a master of the ROCASTER So that is the the audio routing and the submixes that were added into this version or this firmware release The other thing that was added was some more functionality in the RODE central app because Previously this was not really giving you full control over the ROCASTER's settings Whereas now if we come over to the app If I go into audio setup And this looks almost the same as it was before however We have now got these little cog icons At the bottom of each of these things. So this is what looks different that you may or may not have noticed But if I click in there Now we have got access to all of those settings that we've just had a look at on the screen So if I click on here, then I can come into all of those settings You've got full control over the frequency and things like that. Um, so you can just click in here I'm just literally clicking on it. So it's highlighted and then using my scroll wheel to make adjustments If I'm hovering over it. You can just see I can just adjust that with my scroll wheel. Um, so You can then just scroll through all the other inputs, etc And just make changes there So we've now got basically full control to all of the audio processing On the ROCASTER, but we can set that all in the RODE central app So some of these things are just a lot easier to do in the RODE central app It's not as fiddly as you know tapping through lots of screens As you may find that you prefer to do it like that Obviously we can do all the things before of you know Repositioning dragging and dropping these two different fader positions and all of that kind of stuff So no change there. It's just literally on this screen these settings for each of the channels has been added The next thing that's been added is in the device configuration Again, not much change here except for obviously now the routing We've now got all of those custom controls. So now here if I come into my secondary channel You can see that here is here are those changes that we we previously made So I might want to just put that one back. I can adjust this level You can see here more clearly perhaps the fact that when I move this fader It is I'm moving the fader on the ROCASTER And then it is moving up and down on the app So it is a sort of directly linked and it's giving us maybe a bit of a clearer view of that Then we've got on the ROCASTER and then I can just adjust that relative level I can unlink them so that when I move the fader, it's just moving the little faint line there So again, just all of the stuff that we had before I'm just going to pop that one back to mix minus though The other thing then that has been added into the ROAD central app is also the smart pads have been It now allows as I should say to have more control over the SPART pads because before the only thing that we could do in here Was actually add sound effects So this is where you would load your sound effects onto the ROCASTER And in fact, it's a lot easier to do that on here than it is on the the ROCASTER Because there's no real way of sort of uploading them from a file on the sd card or anything on the ROCASTER So this is the way that you add if Add sound files to the pads But now we can basically add all of the effects as well So if I was to click on this and then click in here, I can add different sound effects And add which particular channels I want those to apply to Like that and by the way just coming back to Richard's point earlier about can you apply Sound effects to all of the channels. You can do it for all of the mic channels As you can see here, I could have a reverb and have it applied to If I just come out of here for a second done If I had that applied to you know channel one and two like that You could just apply them separately to these But yeah, at the moment you can't even apply them to those other inputs You know for like the bluetooth or things like that Um, so it'd be good to see that as well as well as just applying it sort of separately To everything just being able to apply it to all of the channels as well Um, but here yeah, so you now you can add these effects. You can also add the mixer effects as well Um, and then also any midi controls here as well So this is basically a um a new functionality because as I say up until now we've only really been able to do the Only really been able to do the the actually uploading of sound files And now this is just sort of thinking you can't see it on your screen But I've got my little my little handy beach ball telling me that it is thinking too much So that about wraps up the the changes to the It's just lost connection. There we go. Got it back again So that about wraps up the changes to the road central app though So, yeah, that would make sense a separate channel for voice effects as well Yeah, so perhaps you I mean in the isolated recording in the went isolated in the multitrack recording It could be useful to actually have The ability to have both. I mean, it gives you the option of pre fader or post fader Could be useful to have actually both of those. So you have got You know both of those options in in terms of the the output Yeah, that would be a good one as well to request as I say they are listening So that's uh, it's good to know when you are you see requests coming in and then they are are actually implementing them I mean there's so much power in the rocaster pro 2 Certainly compared to the one. I believe I didn't actually own a rocaster pro one But the the sort of on board processing power in the two I understand is significantly more than with the one So we have got lots of potential to To, you know, increase the the functionality and things like that that you can do with it There's lots lots of space under the hood. I gather for those kind of things So, so yeah, that's about all for the updates, but they are indeed. Hey, David. Thanks for popping by That yeah, they are making great strides, and it's a great device and and great to see them listening There's just one other thing that I wanted to mention today You know that they've got the visa mount on the back of the rocaster And previously I had got a boom arm in my on my desk setup So it was mounted to the side. In fact, I can probably just show you on this shot here So previously I had my rocaster mounted over here And then I've got my my teleprompter that I'm speaking into with my camera and a monitor below that Which is where I've got the chat and stuff like that. This is my primary monitor 43 inch that I use for positioning things on the screen where I want to do them for screen demos Well, I installed another monitor, which is basically just for some other communication apps over onto this site And so I kind of stole My my own mount for my rocaster which was on this one of these rotating arms here And so I was looking for a different solution for it That was basically a desk mounted one because I do tend to move it around a little bit And so I wanted to be able to sort of move it out of the way But still have it more more so on my desk and basically what I found was on Well, you can get them on amazon But it's this thing and it's basically just it is it's supposed to be a sort of desktop monitor stand So you can see that this is a really heavy base. It's got this arm just here And in fact, I'll drop this into the the chat. I've dropped it into the the description as well And then it's just got this plate on the back that is a visa plate But it's actually I think much better now that I'm using it than the arm because I do still have it on the desk Like this I have still got space underneath it. So if I just flick over to this shot I've still got space like underneath it. I can route all of my So normally I would have this sort of mounted here You can see how I can adjust the the angle of it as well And so I can just sort of pop it back there Like that and then I can have my my stream deck here and this one here And it's actually a much better form factor For me now that I see it than having yet another arm over here So if you are looking for a way to mount the the rocaster pro 2 And you want it still sort of desk mounted, but maybe just elevate it It does obviously also give the ability to have it at a different angle So it is already at a pretty, you know fixed angle But you can then sort of angle this down if you want it more sort of point pointing towards you With more like Angled more upwards like that then you can do that as well So I think it's about 30 dollars or something like that on amazon So I just thought I'd mention that because I know we're all looking to get the the ideal desk setup and get these things Looking looking nice on the desk. There you go.  It feels really sturdy. It's not going anywhere. So as I move it around And yeah, it just works really well obviously intended for monitors But works perfectly for the rocaster in that sort of flat position There you go. So you take that back plate off screw it onto the rocaster and then pop that plate back on Yeah, so yeah, just thought I'd mention that because I've been really impressed with it I love it when I buy these things that are sort of like generic non-brand And I'm always worried about, you know, what they're going to be like when they come Are they going to be, you know, any any good or not? This one is one of those times where it's come back. It's being really solid and really useful I'll go back actually and leave a link to the arms that I use because I've got another non-brand generic Monitor arm that I was using previously. That's also great. I'm just preferring this sort of desk mounted solution But I will go through and add that other one back into the chat as well Um, I hope that has been useful Oh, hello to Kevin just popping into the the last minute there as well nearly missed you Thanks for stopping by hope that's been useful If anyone's got any comments or anything like that about the rocaster that you're maybe watching on the replay Definitely go and check out the discord server. So take one tech.io slash family come and join in there There's a whole channel dedicated to the To rocaster is free to join.

I really appreciate each and every one of you and all of you lovely people watching as well Have a great day everyone. I'll see you in another video very soon


So to understand beta sheets, we're gonna need to focus on the anti-panel case. Let me draw a couple of alternatives for you. Starting out from a long coil, right? The first thing we can do is form what I call a single hairpin. We have a well-defined turn up there and then a number of hydrogen bonds there. Leave a little bit of room there. I can also imagine having three chains or individuals beta strands. And then I have a well-defined turn there and a well-defined turn. And eventually, I will get to something that has three turns and so on. And I'm mostly gonna be interested in these long structures. Now, between these two, as an example, I'm gonna need to have something that goes up, has formed one, and then it has just taken a turn. But I haven't formed any new hydrogen bonds in the second strand yet. So that's gonna be some sort of transition state that I will talk about. This is an example where you need to sit down and define things with paper and pen. And if we do things in smart ways, it's gonna be slightly easier. Let's put some energy numbers here. I already talked about turns. I say that the turn has to be bad so that we'll say that U is the turn energy, free energy, but I'm gonna need to save some writing here. We know that that has to be larger than zero. Otherwise, it would be advantageous to just keep making turns and that would be absurd. Then I'm gonna need to put some numbers here. In particular, if I look at very large beta sheets, just to simplify things in my head, I'll say that there is some sort of free energy beta that is the free energy of a residue to be in a beta sheet compared to being in a coil. In principle, I should have deltas here everywhere, but sorry, it becomes too cluttered in writing, so I need to simplify it. Can we say something about F beta? Is it smaller or greater than zero? Well, if this was greater than zero, it would never be advantageous to have large sheets. It would prefer to be in coil. So we know that F beta must be smaller than zero, at least on average. But then we have this first and the last strand, and here there is some sort of extra effect, right? They can't form as many hydrogen bonds, well, they form that with water, but not inside the sheet. So there will be some sort of extra surface effect. I could call that something completely different, but since these residues, they have the same entropy that I had to put them in a beta sheet. So I'm gonna call that F beta plus delta F beta. For some sort of change that it's on the surface. For now we don't know whether that whole number is positive or negative. So let's reason a little bit about that. One possibility is that that's negative, and that means that it's gonna be good. But in that case, if I just take a single hairpin and make it long enough, that would be stable. And you know what? That happens now in them. It's a very simple and quick forming secondary structure. You've seen it in some of the structures I showed you and you will see it in the future. You can easily make that derivation and it's gonna look roughly like an alpha helix. So in the interest of time, I won't show you that. But if that was the only case we ever had, there would be no point never going to more than a hairpin. And we do know that nature occasionally does form larger structures. And that's because we need a large structure here to make it more stable, even though we're losing entropy. So maybe the more interesting case is when this is positive. Meaning that the single hairpin is still not stable. Something around here is gonna be stable. And I would argue that by the time we get, I'm gonna look at the case when it's stable by the time we're adding a third strand. You could of course imagine that even the three one is still stable and it's not much more complicated. But it turns out that it's not gonna change things by an order of magnitude. And then I argue, and here's why you might have to think a little bit about it that in that case, the transition state is gonna be that one. Why do I talk about transition states? Well, remember your kinetics. So what the kinetics told us is that first, there might be more than one way to form a beta sheet. And in that case, what I'm interested in, then we have multiple parallel opinions, and I'm only interested in the lowest free energy pathway because that's gonna dominate the motion. The book, after having shown what the free energy will go through some detail to prove that there is no reasonable lower free energy path, I'm gonna skip that in the interest of time. So then we're assuming that we're gonna follow this particular path. Along this particular path, what's gonna determine the kinetics is gonna be the least favorable free energy, the barrier. So I need to find what is the worst possible state along the path. This one was still not stable, but because the turn itself is also bad, this is gonna be even worse because here I'm also paying the energy of a turn. But by the time I start forming hydrogen bonds in the third strand here, then I'm going downhill. And then I'm past the barrier. There's one more complication though that this will depend on the length of the strand because if the length here would just be one residue, I would have one residue turn, one residue turn, one residue turn, and that's not gonna be stable either. So the turns are bad and I need to gain enough on the inside here to balance that. So the first thing we're gonna need to assess is how long does the hairpin have to be at least for this to happen? Well, how do we determine that? Well, that would be the case if I have this two strands paired up. And if I keep adding a third strand, for each strand I add, I'm adding n residues here. If that ends up being a plus minus zero effect, then I'm exactly balanced. If the hairpin is shorter than that, it's gonna be bad because I don't have enough energy to compensate the turns. And if it's longer than that, it's gonna be good because I gain more than I pay for in the turn. So for a single strand, I would have delta G or hairpin. That would be roughly U plus, that's the turn, plus the number of residues in each strand multiplied by F beta plus delta F beta because all of them are at the surface, right? But if I add one strand to this, delta G, let's say, call this add one, then I'm adding one turn and I'm adding n residues on the surface. But when I'm adding those on the surface, I'm taking the previous strand and turning that into the inside. So that's just gonna be F beta, right? Do the math, if you don't trust me. So the free energy change for adding one strand is U plus n F beta. And I'm interested in the smallest number of residues this can happen for is when this is zero.  Or if I just solve for n min, that means that n min equals minus U divided by F beta. So that the smallest number of residues I can have on the height here is gonna depend on the energy for the turn divided by the stability of being on the inside of a beta sheet. But let's then look at the specific transition state. So delta F hash equals what? Well, that's almost the same here, but now I have two turns plus two number, the number residues, but that was n min. This is why we needed it. And then multiply that by F beta plus delta F beta. Now I can take this expression for n min. Enter that here, n min is U divided by F beta. But you see the first term there, it says F beta. So that U is gonna cancel that U. Pretty cool. So delta F beta is just gonna be equals to minus two U delta F beta divided by F beta. That term remains, right? And there was a minus sign.  This might not make you a whole lot wiser now, but this is pretty cool because we know that the free energy barrier here, remember for the alpha helix, there I said there was roughly always two or four K cal. And here we have a free energy barrier that depends on the turn. I'm not gonna worry about the turn energy, but it's something that also depends on the surface energy. We're not gonna worry about that either. But in the denominator here, we have something that will depend on the specific stability of a residue to be on the inside of a beta sheet. And this will eventually turn up in an exponent. So let's look at what that's gonna do. I'm gonna need to erase this. So give me two seconds.
