Interesting articles. Though the MS-20 is a neat machine, I wouldn't have thought there would be a demand for a monophonic synth these days, especially when polyphony seems to be almost a given with software synths. I remember trying out an unusual Korg in the late 70s that was both polyphonic and microtonal. There were very tiny pots that you could individually tune, which was cool, but probably impractical. If they could find a way to work in MIDI-controlled microtonal tuning into the mini MS-20, I'd be all in, even though I still have my original.
