Sending the test .rg file off-list to you.

I've been wondering if it's an ALSA problem, because I'm seeing it both
with my onboard soundchip and with my soundcard, and both when using
rosegarden and playing back a (rosegarden-created) midi file with pmidi.

Another symptom I just discovered is that when I play back (using
rosegarden) through one of my soundcard ports that *isn't* initialised
with any bank data (and I can't thereby choose an instrument), the
first part plays back with the (default) piano sound, but the part after
the program change events plays back with the same reedy string sounds
I'm hearing with the properly-configured port.  I don't know *where* these
samples are coming from - somewhere in ALSA?

I'm running a fully-patched Slackware 9.1 system, the latest version of
rosegarden and the following alsa packages:

  alsa-driver-1.0.5a-i486-2.tgz
  alsa-lib-1.0.5-i486-1.tgz
  alsa-oss-1.0.5-i486-1.tgz
  alsa-utils-1.0.5-i486-1.tgz

(although I was having the same problem with the following alsa
packages:
  alsa-driver-0.9.8-i486-3.tgz
  alsa-lib-0.9.8-i486-1.tgz
  alsa-utils-0.9.8-i486-1.tgz
)

Many thanks,
Kona.
