This is an analog synthesizer/sequencer. It sounds very much like the TB-303 and SH-101 bass synths. Sometimes considered the "poor man's 303". It has a very evolved form of TB-303 like programming (more like the MC-4) and SH-101 like controls of the VCO, VCF, VCA, LFO, Envelope and Mixer sections. The LCD display is a great feature too.
