OK, I got this. But two questions arise:
1. Is MIDI clock realtime? If so, it could still be used for simple
alignment purposes.
Gabriel took care of that one.
2. If MTC measures realtime in hh:mm:ss... then why
does it seem so dificult
to have a program that can translate between it and jack timestamping or LTC
or whatever it is called? Or am I again mixing it al up? I assume it's
highly possible.
It is possible and I think there has been mail from Robin or someone
else noting that they have already done it.
LTC is an audio signal, basically a modulated sine wave that encodes
the positional values. Thus converting between it and MTC is not an
entirely trivial operation. But its also not super-hard (well, hard
enough that it needs somone of Robin's skill level to implement).
Another thing: I would/could theoretically use MTC to
sync my MIDI-only and
audio-only apps.
very few "MIDI apps" understand MTC. MTC is really just a
transformation of *VIDEO* timecode into a special kind of MIDI data
stream. it has little or nothing to do with the musical time that most
MIDI apps are concerned with.
