THIS IS A PARTIAL DIY KIT, IT CONTAINS PARTS TO BUILD THE MSW-810 ANALOG SYNTHESIZER. ADDITIONAL ELECTRONIC PARTS AND EXTENSIVE ASSEMBLY IS REQUIRED.
MSW-810 Analog Monosynth
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 device can be built with original CEM3340 and IR3109 VCO/VCF chips or current Alfa reproductions.
The MSW-810 can pair 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). The sequencer comes with all the surface mount components pre installed and requires very basic assembly. Please note: While the sequencer is provisioned for accent, the 810 does NOT have accent circuitry, a mod board is planned to add this functionality.
A non-sequencer analog only is available as well but please note this device is 100% accurate to the CMU so CV/Gate control ONLY, no MIDI.

MSW-810 Synth Kit
This kid includes:
- 1x MSW-810 PCB
- Complete Slide Pot kit
- All NPN/PNP transistors
- Power supply DC to DC (replaces the coil in the original device)
- TC4013 Flipflop
- TC4006 18 stage shift register
- 2x BA662A clowns
- "VR2" 500R Right Angle Trimmer (out of stock everywhere)
This is the sequencer for the MSW-810. This is a machine assembled PCB that includes all parts fitted all EXCEPT the tempo pot, pixie, and headers.
This kit includes:
- 1x Assembled PCB
- 1x C1M potentiometer
- 1x Dust Cover
- 1x Tempo Knob
- 1x Pixie Processor
- 4 x assembled ribbon cables
- 1x I/O PCB Kit (assembly required)
This device is provided programmed and ready to use but requires calibration. An accurate volt meter with frequency detection is needed.
This kit Includes:
- all hardware to mount the main board and I/O board.
- Set of slider caps
- Tempo knob (seq version only)
- blanking panel (non-seq version only)
