Subject: [Ensoniq-VFX-SD] SD-1 32 analog values problem









A short time ago the display of my SD-1 32 showed something like

"battery voltage low". Also it was out of tune and all the voice have

LFO modulation (even if the modulation wheel is at the lowest

position). So I replaced the battery (I am a technician) But it didn't

solve the problem. I checked all the analog values through the

testpage and they are all wrong (about twice as low as they should

be). I now am suspecting the circuit around the 4051 and opamp ; this

circuit collectes the analog values and transfers them to the A/D

converter inside a Processorchip.

Has anybody had the same problem ?
