Oberheim Four Voice FVS-1 SEM

via this auction

"As you can see from the pictures, a MediaMix aftermarket kit was installed in this synth. The kit features 3 separate master CV (control voltage) adjustment knobs connected to each SEM, a knob to adjust pitch bend intensity, and a knob to adjust VCF bend intensity. Pitch bend is on the X axis and Filter CV (control voltage) is on the Y axis. The small switches turn on and off their related features. The large switch is not connected. The 5 1/8 in jacks are not connected either.

The 4 switches on the top rail of the synth are part of a kit that is still installed, but no longer connected. The 4 switches could potentially add sine wave capabilities to each SEM, but I am not sure if the kit is working properly."
