whell I have a problematic CV on I/O channel
actually when turning on desk..i/o cv seems to work OK, but after 2 hours ..cv goes crazy...and range is smaller after 3 hours it goes to distorsion in all range of fader is same level
tried another VCA , same thing, and another...again same thing
replaced transistor in that area
tl080
but still nothing
actually from fader I have signal and its all the time OK but after 100K reesistor on input of tlo80 pin 2 evrything goes wrong...
same effect when using VCA busses 1-8 so problem is in fader ACN buffer around TL080
anybody any idea...
