--- Comment #13 from Jörg Höhle hoehle@users.sourceforge.net 2011-01-12 15:21:52 CST --- Luke, I haven't heard from you since July. Your trace trace:midi:OSS_MidiInit OSS info: midi[0] dev-type=0 capa=0 MidiOut[0] name='L"Midi Through Port-0"' matches what I mention in http://wiki.winehq.org/MIDI
If you don't have MIDI HW, the app's MIDI output will be sent to your serial HW where nothing is attached. Given such a setup, it's normal not to hear any MIDI music. Hence if you don't respond, this issue should be resolved as invalid.
MIDI output should work with OSS, but you need to set the mapper to use port #1 where you have Timidity running trace:midi:OSS_MidiInit OSS info: midi[1] dev-type=0 capa=0 MidiOut[1] name='L"TiMidity port 0"' like I explain in the Wiki page as well as comment #12. I asked you to check this in comment #10.
BTW, please remove the "page fault" from the subject as per comment #3.
