I still have the unit, packed back in original box, in the garage Maybe one day I'll try it again. Too much of some aspects, not enough of others. The unit did work, it did produce midi data, but it was pretty useless data. You could then make sounds into the unit, and capture the resultant midi on a connected computer. The unit also has a standard midi connector, and a couple of slider controls for (I think) volume and something like 'threshold'. This box has a socket to plug in a microphone or (I think) a guitar. Way back in October 1992 I got a Roland unit, a CP-40. I still suspect that there are serious limitations with what can be achieved. MP3 or whatever) and the immediate midi file, before it's been touched by human intelligence. So it remains that I would just LOVE to study a midi file so converted. I follow on from my comments above, and further to looking at the info referred to by Eddie regarding the Widi system, I remain somewhat sceptical about the idea of converting an audio file to midi.
