--- Comment #6 from Andrew Eikum aeikum@codeweavers.com --- Interesting. I don't know a lot about how our MIDI support works, or MIDI in general. I've definitely never dealt with hardware MIDI support. You could look into debugging MIDI at the ALSA level; perhaps we're sending MIDI messages too late.
