For some reason the other voices sound fine. 3 was the worst. After cleaning things up a bit..now 2 is what three was. Oh and I swapped out the fast 4051 analog switch and op amp that drives the vca in. I was seeing a sawtooth there... leaky S+H I was thinking? Also 5 doesn't tune yet I can turn it back on and it sounds ok. it's envelope is strange though. Sustains with that level at zero then turns off w/out it moving. That makes no sense. hmmm. rechecking that..anyway if anyone has seen anything similar... I saw something kinda similar on a siel dk600 where it was that voltages were peaking on the DAC out higher than the reference voltage on 4051's. I adjusted the dac though and...why would it be doing it on three and not the last three?
