Analog Semi-Modular Synth Voice
The CELL is a fully analog semi-modular synthesizer system that is ideal for making bassline sounds, techno music, acid house, and beyond!
The CELL combines some east coast and some west coast synthesis elements. It contains a single voltage controlled AS3340 oscillator (VCO), a low pass voltage controlled AS3372 filter (VCF) and amplifier (VCA) combination, and an AS3310 voltage controlled envelope (EG), a voltage controlled slope (VCE). Lastly there is the Random Sequencer (RND) that ties the various modules together. There is a "normallization" path that internally patches the individual modules together so that a user can have a basic patch available without the use of patch cords. The specific circuits were chosen for their stability, versatility, availability, and ease of construction.
