is it possible to convert a Midiclock-Stream to audio? and convert this audio-recording back to midiclock? so i could use one of the RECorder-channels for the midi (clock start stop notes and so on) are there already devices out there? i can remember that 30 years ago such things as midi tape exist... or is it maybe a cheap trick that can be solved with an optocopler an opamp and a few lines of code? its done   VIDEO-Overdubbing a JP80
