Hi Michael, The problem is isolated to two new (old) voice cards I purchased from Doug t= errebonne, they came with New cem3340g series chips and these seem to be causing chaos, he has suggest= ed I put an inline resistor 1m ohm between pin 1 and the tuning pot, whether= this works or not I don't know but I'm going to try it, the other thing is t= he new cem chips tune up about an octave lower than the legacy cems. Thanks for the information though I'm going to bank that, this is such an unusual synth with really sketchy se= rvice notes so I'm learning all the time with this synth.
