MSW-810 Analog Monosynth with TB-303 Sequencer. 

Fully assembled and Calibrated.

The MSW-810 is a faithful recreation of the CMU-810 Monosynth which was designed as a synth expander for the 1983 CMU-800 computer music production system. At its core however, is the tone generator of the MC-202.  

The MSW-810 pairs this synth voice with the legendary TB-303 sequencer Pixie emulation that runs the original TB-303 mask ROM code and also adds MIDI control (note and sync).  Accent is added on the rear panel and features accent in via 3.5mm jack and Accent amount.  Since the CMU-810 did not have accent as a feature, the 202 accent circuit was added as a mod.
