Hold a whole note: observe the envelope jumps back to some random spot in the middle instead of behaving like a normal ADSR envelope, almost like there's a random pre-delay. It's a little sporadic, but seems to happen 80% of the time or more for me. Oddly, it seems that mapping to the `Filter Envelope` to the `Cutoff` in a similar manner (leaving the `Env Amount` at 0) has a similar behavior for the visual display but does not affect the sound audibly. Other mappings seem to have similar issues like OSC pitch, etc..\r\n\r\nOne other note: it seems after loading the 2nd preset and the 1st preset again, the issue is no longer present. Maybe it's something as simple as fixing the init values? I hope it could be fixed pretty easily. The init patch having this issue is a non-starter for using it with the One-Synth-Challenge -- which I hope, one day will happen -- because people have to design patches from scratch a considerable amount."},"comment":{"url":"https://api.github.com/repos/mtytel/helm/issues/comments/223473482","html_url":"https://github.com/mtytel/helm/issues/83#issuecomment-223473482","issue_url":"https://api.github.com/repos/mtytel/helm/issues/83","id":223473482,"user":{"login":"mtytel","id":311087,"avatar_url":"https://avatars.githubusercontent.com/u/311087?v=3","gravatar_id":"","url":"https://api.github.com/users/mtytel","html_url":"https://github.com/mtytel","followers_url":"https://api.github.com/users/mtytel/followers","following_url":"https://api.github.com/users/mtytel/following{/other_user}","gists_url":"https://api.github.com/users/mtytel/gists{/gist_id}","starred_url":"https://api.github.com/users/mtytel/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mtytel/subscriptions","organizations_url":"https://api.github.com/users/mtytel/orgs","repos_url":"https://api.github.com/users/mtytel/repos","events_url":"https://api.github.com/users/mtytel/events{/privacy}","received_events_url":"https://api.github.com/users/mtytel/received_events","type":"User","site_admin":false},"created_at":"2016-06-03T02:08:30Z","updated_at":"2016-06-03T02:08:30Z","body":"Yea the last note played could make more sense. Especially with the LFOs\r\n\r\nAs for where the audible error is occurring. I'm *pretty* sure it only happens in the sections that can turn on/off like the formant filter. I'm doing this thing where I group values together to disable them all at once but the polyphony doesn't seem to propagate through which is causing the audio glitches.\r\nIf you do find some other parameters where one note's polyphonic modulation affects another one let me know, because it could be a different issue.\r\n\r\nAlso, when I have a build with a fix, would you be willing to test it out if I sent it to you? I'd really appreciate getting a verification before I made another release."}}
