Again… great insight Brach and thank you for all your help.
I pulled the microcontroller with my IC puller (side note… all pins are nice and straight). Then I powered up the pedal and metered pin24 to ground while turning the rate knob.
When the rate knob is fully counterclockwise, I’m seeing 0.19V at the IC socket. Then as I turn the knob clockwise, I see small scaling increase until I hit about 1/8 travel. At that point, it jumps to 4.98V and remains there for the rest of the wipe. To clarify, I’m seeing 4.98V for about 7/8 of the pot’s sweep.
