Pedal Interface
The Q142 pedal interface offers a way for foot pedals (actually any switch or potentiometer) to control your synthesizer.
Each of the two independent sections allow simple switch pedals or variable pedals to create control voltages that can be used to control virtually any module in the system.
Control volume, filter sweep, pitch bend, pan/fade, and more. Various voltage levels and polarities are produced for each pedal.
These merchants probably sell this module. Huh?
