It might make more sense to bump it up to midi 137 which is `22350.606811712252 Hz` so that it's not prematurely cutting frequencies out.\r\n\r\nI appreciate the difference will be miniscule for a lot of people (most adults can't hear above 16KHz anyway) but on principle I think this needs to be changed.\r\n\r\nOnly making a note here - I can make the changes when I have a bit more time."},"comment":{"url":"https://api.github.com/repos/samaaron/sonic-pi/issues/comments/91845526","html_url":"https://github.com/samaaron/sonic-pi/issues/427#issuecomment-91845526","issue_url":"https://api.github.com/repos/samaaron/sonic-pi/issues/427","id":91845526,"user":{"login":"samaaron","id":369,"avatar_url":"https://avatars.githubusercontent.com/u/369?v=3","gravatar_id":"","url":"https://api.github.com/users/samaaron","html_url":"https://github.com/samaaron","followers_url":"https://api.github.com/users/samaaron/followers","following_url":"https://api.github.com/users/samaaron/following{/other_user}","gists_url":"https://api.github.com/users/samaaron/gists{/gist_id}","starred_url":"https://api.github.com/users/samaaron/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/samaaron/subscriptions","organizations_url":"https://api.github.com/users/samaaron/orgs","repos_url":"https://api.github.com/users/samaaron/repos","events_url":"https://api.github.com/users/samaaron/events{/privacy}","received_events_url":"https://api.github.com/users/samaaron/received_events","type":"User","site_admin":false},"created_at":"2015-04-11T13:41:12Z","updated_at":"2015-04-11T13:41:12Z","body":"Happy to raise it.  However the value of 130 was determined through experimentation as the highest val that didn't cause the synth to explode horribly. This value may be different with different synths and param vals such as res. \r\n\r\nOne option would be to bypass the lpf if a cutoff or res val isn't specified just like we already do with sample.
