They change as you would expect with the buffer sizes (I think so anyway - I haven’t actually calculated how many samples is 1ms at each rate and worked it out)\r\n\r\nI’m not sure why the input latency is less. Different interfaces vary quite a bit in these figures, with the same buffer size settings.\r\n\r\nThis doesn’t change when I change the plist.\r\n\r\nI rebooted after changing it - I presume that reloads it ok? or is there a cache that needs updating? \r\n\r\nI also tried unloading and reloading from the terminal using the same commands that are in your install script. It still reports above figures however the plist is set.  Since the above figures include the 64 samples reaper buffer I think it is actually using the 2.2ms latency, even when it is set to 4.2ms.\r\n\r\nThese are very good figures so I have no complaints, but it is strange that it doesn’t change when the plist is changed."}}
