Hi.
This question might sound stupid to some, however, I have never done
something like this before in Linux and would love to hear your tipps:
I am trying to record a multitrack thing with my x0xb0x. In other
words, I'd like to record *two* tracks generated by the external synth
sequencer, but in sync to each other.
Since I have never played with transport things, I am looking for hints
on how to do it. Since I am limited to command-line tools, I would like
to do it with ecasound, backed by JACK.
Right now, my x0xb0x emits MIDI clock sent to a DR202 drum machine.
Can I somehow record the MIDI clock along with the first track,
and resend it in the second recording so that everything is in sync?
Or, should the PC emit MIDI clock (how?) so that everything starts in
time?
Any hints are very welcome.

Hello Mario!
It gets difficult, but I think not unmanageable. My tools of choice 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.
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.
Warm regards
Julien

I was already guessing that it would get complicated, but so much? :-)

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.

Hello Mario!
You can record a MIDI track and audio at the same time, only the background
setup will look a little ugly. :-) The problem with Klick might be, that you
have to program tempo map or keep at one tempo/time signature.
The script is attached. The website is still down. I'll keep on trying. Good
luck!
Warm regards
Julien

Hello Mario!
OK, my website is up again and the jack_midi_clock sources are here. It's a
complete tarball. The source is easy to build:

I hope, this is of use to you.
Warm regards

Is there a particular reason that you don't want to use a GUI
application? Something of this sort should be fairly trivial using
either Rosegarden or Ardour 3.

Tried, but didn't find your original mail anymore, its actually at least
4 years ago... So its a bit hard to answer your question, since I will
have to use my memory, which might be a little bit faulty. But as
far as I remember, you didn't like the concept of ATK calls being
necessary to beef up accessibility. If I remember correctly, you said
something like "this should be simpler or not necessary" or what not.
To be
honest, back then I thought you didn't understand the issue at hand. But I was so
frustrated about your reaction that I totally dropped the idea of
working on inproving Ardours accessibility. Its no fun if you have to
explain yourself over and over again.
The patch was doing something simple like associating a label with the
corresponding input field, such that the screen reader would actually
know the label for the particular input field... This is pretty normal
accessibility stuff, but on reject I totally lost motivation to fight
windmills.

Right now, my x0xb0x emits MIDI clock sent to a DR202
drum machine.
I may be missing something, but can't you just run the midi clock
into
jack, and then split it to two independent midi outputs, and then to
your synths?
If one of your synths has "MIDI Thru" you don't even need your
computer, just get the clock to both of them over one midi chain.

Yes, of course. The problem is I only have one synth, and would like to
record a piece with two voices.... So I need to record twice and have
the second recording synced to the first one.
