I have tracks in RG whose sound is produced by qsynth, and others
that are played by hydrogen. Is there a way to record what I hear
in RG? I can record separately the qsynth tracks by choosing
Jack:qsynth, and the hydrogen tracks by choosing Jack:Hydrogen-1
as the recording device in audacity, but then I have to
(re)synchronize them. Other choices for recording device are
Jack:rosegarden and Jack:system, but they apparently don't hear
either of the tracks.
Life would (I think) be simpler if audacity appeared as a writable
client in qjackctl. (Should it, by the way?)

Maybe qarecord? It's just a simple writable jack client that can record
all system output to a .wav file. No whizz-bang features, but it does
its job well.

That would be fine. But whatever I do with it, it crashes saying this:
Error opening PCM device plughw:0
Could not open PCM for capture.
can't set sched_setscheduler - using normal priority
qarecord: pcm.c:689: snd_pcm_close: Assertion `pcm' failed.
I don't know if this is because of some bit rotting (the last version
I found is from 2004).
BTW, I also tried jackrec, a command line utility, with port
system:playback_1 (reported by jack_lsp), but it said
source port in attempted connection of system:playback_1 and
jackrec:input1 is not an output port
cannot connect input port jackrec:input1 to system:playback_1
On to ardour now...

There have been threads recently on jack limitations with Audacity.
Maybe Ardour will do it.

jack_capture can do the job.

I'm sure it will. If I'll be able to make it do it....

Indeed it should. But it seems to just hang before even creating the
output a file (when I start it with -fn output.wav).
After trying three simple command line utilities and failing with all,
I'm beginning to suspect that there may be a problem with my jackd
setup.

The -fn argument is'nt the best choice to use jack_capture, better use
it like that:
jack_capture --channels 2 --port system:playback* output.wav
or use jack_capture_gui2

Thanks for the sugestion, but it doesn't seem to help. jack_capture
doesn't crash, doesn't create output.wav, just sleeps (strace doesn't
show much activity after the initial setup) until killed.
or use jack_capture_gui2
Ditto :-(

IIRC, JACK support in Audacity is pretty new -- so it's possible that you have a
version without JACK support.
However, nearly all versions of Ardour do what you want. Ardour is a pretty
powerful program... so unfortunately it's a little harder to use than Audacity.

Yes, it looks a bit intimidating... but sooner or later I'd have to
learn to love it anyway :-)

If you have set up jackd as output in qsynth and hydrogen,
that should work.
Don't forget to enable the jack ports for recording in Rosegardens
midi-devices dialog.
And activate at least one audio track for recording.
In the track parameter panel, there may be some more options (select
recording device etc.)

Now I'm thoroughly confused. In the track parameter panel there's
indeed an option for the device, but shouldn't that be "audio"? (The
others being all midi-related.)
Are you suggesting, that an audio track can be configured in such a
way that that it gets its input (for recording) from the other tracks?

Yes.
Let me be more detailed, how to realize it:
1. First start jackd (I recommend to use qjackctl for doing that. You
can see the created connections there too.)
2. Start qsynth
3. Start rosegarden
4. in RG in the device manager, create a new device, name it QSYNTH
and connect it to qsynth
( the entry is called somehow like "131:0 snyth input port
(qsynth:0) (write)")
5. select a MIDI track. in the playback parameter panel choose the
QSYNTH device as output
Further select instrument, channel and program for the track
using the QSYNTH device
# for testing, playback the midi track now. You should hear it.
6. select an AUDIO track. Make it stereo. As input select "In 1"
7. use QJackCtls connection dialog (audio-connections)
- delete the connection system input (capture) ==> rosegarden (record)
- (optional: delete qsynth ==> system playback (out) )
- connect qsynth to rosegarden (record) input
8. activate the audio track for recording (red LED)
9. press the record button in the Rosegarden transport panel.
the playback starts and the midi track is being recorded to the audio track.
(note: if you de-connected qsynth from system-playback, you may
not hear anything now)

Thanks for the detailed and clear description! Steps 6-9 were
completely new to me.
