I meant send it to me privately, instead of mailing a copy to all 50,000
Ubuntu Studio users who are subscribed to this list.

You select a bank with a particular MIDI controller. Something like
Rosegarden insulates you from the details of how this works, and I don't
quite remember them myself.
Anyway, as I suspected, changing banks doesn't have anything to do with your
problem. It says:
No instrument mapped to tone bank 0, program 22 - this instrument will not
What this means is that there is no program 22 in tone bank 0. This doesn't
mean you need to change to a different bank, because there isn't another
bank. Tone bank 0 is the only bank with the default setup as TiMidity +
Freepats ship out of the box.
If you look in /etc/timidity/freepats.cfg you can plainly see that there is no
program 22 in tone bank 0, just like this error indicates:
0 Tone_000/000_Acoustic_Grand_Piano.pat amp=120 pan=center
They skipped over program 22. I don't work at Freepats or TiMidity, and I
have no idea why this is so.
1) Load the MIDI file into something like Rosegarden and change whatever is
trying to use program 22 to use some other program. (You have options from
there. You could export the result back out to a .mid file, or run TiMidity
as an ALSA synth client (timidity -iA), and play TiMidity directly from
2) Edit /etc/timidity/freepats.cfg (as root, of course) and map program 22 to
something else, just so you'll get some result here.
3) Run TiMidity with some other soundfont. (I just spent 20 minutes digging
around in the 897-line man page trying to figure out just how to do this, and
I have no clue yet. It does say it can run using .sf2 format soundfonts, the
most common type, but damn if I see what string of text to feed it to make
that happen; nor can I hit on what string of text to search for to find the
4) Abandon TiMidity in favor of something with a friendly interface, like
QSynth. (Unless you're using it for some purpose QSynth can't accomplish.
It does have some unique functionality.)

That's probably a realtime priority issue or something. Not my area of
expertise. I'm totally dependent on the kind folks at projects like Ubuntu
Studio to save me from my abysmal ignorance about such matters. (I know what
I don't know, but you have to be a rocket scientist and breathe and sweat
this realtime priority latency gobbledygook to get anything to work. I'm
glad there are people willing to wade through all that insanely complicated
garbage on my account, because I'm certainly not up for the challenge myself.
