Sycologic PSP Percussion Signal Processor

The Sycologic PSP Percussion Signal Processor is a MIDI device. Signals are generated via pickups placed on percussion devices and these signals are converted into MIDI signals to control other MIDI instruments.

Stewart Copeland had this device at his home studio around 1985/86, as seen in this picture from a facebook post. In 2015, the Sycologic PSP from Stewart's collection was sold on ebay as a non-functioning unit for $26 (US dollars).
