I saw the infamous increase MIDI pool error for the first time this weekend.
I, too, was not using MIDI, although my card does support it. I don't think
I had any of the ALSA MIDI modules loaded, though.
I had the master channel routed to the inputs JAMin, and the outputs of JAMin
hooked up to the inputs of a stereo track in Ardour. This track was set to
record and was muted. I'm not exactly sure when the error actually occurred.
It was either when the all of the source tracks feeding into the master
channel ended, or when I clicked stop in Ardour. The two events happened at
roughly the same time. Increase MIDI pool error, Ardour crashes, session
corrupted. Sorry, didn't save the corrupted session for analysis.
Fortunately, I had made a backup of the session immediately before the crash.
Restored that. Did the same thing without any changes, although I might have
stopped and restarted jackd. Worked great. Didn't see the problem any after
