Hi there, one cion modules I built recently isn't functioning correctly and I'm banging my head against the wall a bit.
When it turns on the EOC light comes on, if I trigger it the light goes off. The attack seems to work as it should and I can change the log/exp knob works. I just don't get any decay. It raises to about 9.5 volts and holds there.
Where about on the pcb should I be looking for problems?
