Qbix: it is midiconfig in 0.74 and friends and dosbox should pass it on without decoding.
I'm trying with Duke Nukem 3D but it still doesn't work :(
'MIXER /LISTMIDI' gives me
0 "Microsoft GS Wavetable Synth"
1 "Timidity++ Driver"
2 "Out To MIDI Yoke: 1"
...
9 "Out To MIDI Yoke: 8"
the ports are all set in Timidity. By using the tool I mentioned earlier to set the default MIDI device, and selecting Timidity++ Driver or Yoke 1 the media players automatically use Timidity for MIDI synthesizing. But no DosBox.
My [midi] section:
mpu401=intelligent
mididevice=default
midiconfig=2
also tried:
mpu401=none
mididevice=none
midiconfig=1
Which still gives me MIDI music?! This is weird.
I don't get it.
