I've finally gotten something reproducible. I don't know if this is a bug with the mtpav in particular or the sequencer, although I'd think someone would have noticed if it were the latter by now.
Anyway, notes or messages are _still_ getting lost. It seems that note messages are getting lost when playing "overlapping" notes while two MTPAV (or other?) devices are being sent to. Let me illustrate: Track 1: __ __ __ __ Track 2: _____ _____ _____ _____ In my case, I play the first to device #1, and then the second to device #0 (while the first is still playing). I lose Note-on or Note-off messages somewhere... you can hear that notes won't fire, or they won't turn off. Of course, each track alone plays fine. Also, playing a second track with no "overlap" seems to work fine, too (as in playing track1 on both devices). I have attached two tracks in MIDI form, created by Seq24 (http://filter24.org), which follow this pattern. You can test them using pmidi on the command line---the same problem occurs. I use them as follows: $ pmidi -p 72:1 track1.mid $ pmidi -p 72:0 track2.mid # in a different term, while the first # plays Any fixes, pointers on where to look in the code, or general ideas would be greatly appreciated. -- Ryan Pavlik <[EMAIL PROTECTED]> "I distinctly remember dancing on your grave." - 8BT
