PRC

Analog Drum Synthesizer

CATOFF PRC is a single voice drum and percussion analog synthesizer module.
We decided we didn't want to make a clone 808, 909 or another one. Instead we have created our own circuit and would like you to create your own unique sounds based on classical analog synthesis engines.
This module consists two parts: a noise and tone sections. Each of this sections is equipped with its own Volume control and has a few adjustable synthesis parameters, two of which have CV inputs for modulations. In addition there are two switches for variable sound changes one of which the Tone Range (Lo and Hi) and waveform SQ –square or TR - triangle. And also manual trig button and trig led indicator on the top of this module
