I have a CS40m that I am restoring to the best of my ability.
Power supply rebuilt, and all caps replaced.
Got most of the unit working. However,
- the sample and hold modulation isn't working. When selected on a VCO, and depth increased... pitch just decreases and stays, no change in pitch from LFO.
- Also, writing a patch does not store. All the patches are silent, or have a noisy quip. After attempting a WRITE to a patch number, that patch just remains silent.
Any suggestions on where to start tracing these issues? I am a novice/intermediate tech.
