Vintage Synth Repair

Hi Steve

There is also a Yahoo group for Oberheim synths. The link is:
http://launch.groups.yahoo.com/group/oberheim/

The manual will explain how to run the calibration for the voices. If one is still weak it may be one of the the CEM3396 voice chips has failed.

There is a unison mode where you can play all the voices in mono or if you set the midi channel to G1 (up to G9) each midi channel will have a mono voice for the six voices. The starting channel for G1 is channel 1, G2 is channel 2 etc...
