I did not yet dive in with the scope, but could do that in the next couple days.
Just tested symptoms again.. the pots which have the unusual sound are the following:
- All 4 VCF pots: Cutoff, Res, EQ, and KBD
- EG Sustain
- MG Level
- PW/PWM
If someone has a general suggestion of what to be expecting to look for with the scope at the components in relation to this list, i am all ears and very thankful. I have some circuitry and component knowledge but nothing too advanced yet, and this is a great chance for me to figure some more stuff out. I very much appreciate the help.
