hi folks, got an issue im wondering if you could point me in the right direction of....
the VCF envelope of one voice on my cs-80 wont open/close properly. im 100% sure its not a HPF/LPF issue, as they both sweep through the ranges properly. its just that the attack/decay settings dont cause it to open/close. i tried to calibrate this, but using the service manual instructions, i couldnt get the attack ttime to change at all via the trim pots.
i believe there is a filter EG chip on the voice cards, right? possibly a bad chip?
im looking forward to getting her to 100% shape. i honestly think the last time i enjoyed an instrument this much was learning "stairway to heaven" on gtr when i was 12 yrs old. i walk away from this thing in awe every time i sit down to play it....
thanks guys!
