Thanks. That confirms that what I'm seeing in JACK isn't unusual or
unexpected.

It's probably not finding the midi device... do an

Checked first with lsof:
Once running, with the device selected that I expect to see as the
physical "MIDI out" connector on the CS46xx interface:
rosegarde 25807 syl 14u CHR 116,1 125373 /dev/snd/seq
For reference, aplaymidi (which _does_ produce MIDI output) also holds
the same device file open:
aplaymidi 25846 syl 3u CHR 116,1 125373 /dev/snd/seq
so, alright, a trace of the rosegardensequencer process is in order ...
In response to Markus Herhoffer's suggestion, though, I ran the strace
test with JACK not running, and sure enough, I got the MIDI output, tried
again without strace (still no JACK), and again MIDI output was working!
I won't bore you with the strace output! :-)

I'm not convinced of that. For example, I do need to "connect" (via
qjackctl's "connect" screen, "MIDI" tab) "80:CS46xx" to
"129:FLUID Synth"
to be able to control that software with my MIDI controller.
As far as I know there are some problems in the
compatibility of
qjackctl and Rosegarden (described in "Rosegarden Companion").
I would love to get a copy of that. Anyone know of its availability in
Canadian bookstores, or should I be looking to purchase a copy online?
So you should use only Rosegarden for linking the MIDI
devices.
Ok, as mentioned above, I tested with JACK not running, and sure enough
I'm now able to get MIDI output from Rosegarden. Thanks to all who
replied about this! The beautiful sounds of my music theory final from a
couple of years ago (ok, well, it's still beautiful to MY ears!) emanating
from various MIDI synthesizers and a piano sample! :-)
I continued testing and found that if I start JACK _after_ starting
Rosegarden, it seems to do the right thing. Should I perhaps simply have
Rosegarden start Jack, or am I asking for different trouble if I do that?
(I do still want to use JACK because some of the applications I expect
to be making heavy use of use it or require it ...)
This software (all of it!) is such a beautiful thing! Thanks once again,
and good night! :-)

When I launch qjackctl, the window is labelled JACK Audio Connection
Kit. Despite this, they are not the same.
Qjackctl is a GUI written to manage JACK; but, as I understand it, it
also provides direct control of ALSA MIDI connections.
Midi has actually nothing to do with Jack. Jack
cares only about
audio streams.

That's interesting. I have had various difficulties getting Rosegarden
to send MIDI to fluidsynth (managed with qsynth). Maybe I should try the
same?

It's entirely possible that there is confusion such as you mention, on
my side of the keyboard. I used to work in live sound, and have worked
for the last 10 years as a computer analyst, but although I've dabbled
a little (mostly with Rosegarden-2.x, and sound editting applications
that were contemporary to that version), I'm still very new at using the
computer for audio/MIDI manipulation, let alone for recording of any kind.
I'm still very comfortable with the built-in sequencer on my ESQ1, for
example, though I do hope to be able to synchronize that with Rosegarden,
and perhaps something like Ardour, but it should give you an idea of
where I stand regarding this type of software: it's all very new to me,
and I do feel like a wide-eyed kid in a toy store. There's a learning
curve, and I'm not quite at the bottom, but I am quite near it and hoping
to get over the steepest portions quickly.
I have had various difficulties getting Rosegarden to
send MIDI to
fluidsynth (managed with qsynth). Maybe I should try the same?
It hadn't occurred to me last night to try Rosegarden to fluidsynth (for
which I also use qsynth) again (I was really quite thrilled to finally
hear Rosegarden play a sequence imported from a Rosegarden-2.1 file
through my hardware synths and sampler, that the possibility of software
synths completely escaped me for that time). I certainly imagine it
will work the same: start Fluidsynth, then start Rosegarden, with no
JACK intervention, and I _expect_ that it will work (Rosegarden _was_
aware of FluidSynth running in my earlier attempts, but I also had JACK
running during those times, and was not seeing any MIDI from Rosegarden
to FluidSynth).
