This is pretty much exactly what I'd been planning from the very start... (minus the reverb)
I'll have to look into it more to see how she deals with the time it takes to step from one track to the next... I guess it's only a few milliseconds vs a half second per rotation.
Also, since she's accessing the RW heads directly, (if I understand correctly) there's no problem with the write-gate, which prevents writing over the beginning of the track... and thus *stops* writing immediately when the index pulse comes (which would otherwise be fed back to automatically step to and continue recording onto the next track). One of those things that I ran into as a result of scaling up my original plan to digital/PWM rather than just going with the original idea of hooking the heads directly to a tape player. Heh. (the plan, there, was that I've never been particularly good at analog, so why not use something designed for the purpose of reading a magnetic head, and just electrically change out the head mechanism?)
What I don't understand is how it's possible this vid is 14 years old and I never heard about it until now... As a passing thought in a Friggin HaD podcast, to boot. Do you have any clue how many times I searched for this since, oh, probably 1999 when I got the idea?!
She even took it to the MIDI controlled sample-per-track idea. Sheesh. Yeah, that was in my plans, too. (BTW, which'd be a bit like a monophonic melotron, hmmm). But, doing-so with a hard disk... I dunno, Jerri... They spin *way* faster than 1/2sec per rotation... Though the autostepping idea used here with a floppy could probably be done with an MFM drive... though, as they get rarer and rarer, that'd be a bit of a shame unless it was already broken...
TODO: there are other vids, too... probably some docs to look into.
