for that experiment have been: midish, Nama/Ecasound, jmc (Jack Midi
Clock) and klick (jack-aware metronome). There was j2a_midi_bridge and
a2j_midi_bridge, but I think JACK might now include software ALSASEQ
ports. So you could dispend with a2j_midi_bridge.
So you see, that you have a jackmidi->alsa_seq->jack_midi passthru
connection. You start jack_midi_clock and then klick. Klick will give
the the tempo in JACK. Because jack_midi_clock syncs the midi clock to
jack_transport, which - I think - is the most reliable way of doing
it. Then you can use midish, with its master clock set to the
jack_midi_clock port. Then in midish you can record MIDI and control
its start stop by Nama/Ecasound. Of course for the original recording
just midish without all the other software will do.
I was already guessing that it would get complicated, but so much? :-)
Does anyone have a more modern idea on that? I think
jack_midi_clock
isn't available anymore. I have a package. But my site is down right
now. I'll look it up and mail it again. I can also send you my script
starting all of the "backend" software in one go, using GNU screen.
A script would highly be appreciated. From your description, it looks
pretty complicated. I was sort of hoping I could just record
the MIDI track along with the audio, and resubmit the clock ticks on the
second take... But I guess I was pretty naive.
