Kitchen table manufacturing – little-scale is making GenMDMs: “I now have the majority of the remaining boards assembled – to be precise, 20 out of the remaining 24 interfaces have been constructed.”
GenMDM is a music interface for your SEGA Genesis or Mega Drive console.
Use GenMDM to write sweet chiptunes using your favourite MIDI / audio sequencing software. GenMDM will appear as a MIDI output device on your Windows, Mac or Linux-based computer. GenMDM will respond to MIDI notes and MIDI CC data, and will give you a high degree of real time control over the sound chips inside of the SEGA console.
All voices and sound functions of the standard SEGA FM and PSG sound chips can be controlled via MIDI. There is a small FAQ in this thread on chipmusic.org. You might be interested in reading it.
