LAST RUN PRORDER: I've exhausted the supply of parts to build these and they will be discontinued after the last batch is sold. Last batch of cases will be delivered in January and will ship then
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.
