First x0x went off without a hitch... had to do a bit of debugging on the second one, but it's 99% done.
The one problem I'am having is that after playing a note, if I turn up my volume really loud I can hear the note still being played very quietly... the sounds reacts to the VCF and tuning knob, so there is still some oscillation going on.
Thought it might have been Q39 base which shows around 27mv when not playing, but my first x0x (without this oscillator issue) shows the same.
It's not a major nuisance, but it's just "one of those things" you want to try and fix. Any advice on what to test and try to track this bug down is appreciated.
