>Description:
I installed gnu-solfege software from pkgsrc. The software make no sound.
If I go in File > Preferences > SoundSetup and I try to choose 
"Use external MIDI player" then I try to test this configuration I get
this on std output:

info: ignoring duplicate tone: (NoteOnEvent, pitch:48, vel:100, time:(Rat 0/1))
info: not stopping, not playing now: (NoteOffEvent, pitch:48, vel:100, time:(Rat 1/4))
info: ignoring duplicate tone: (NoteOnEvent, pitch:52, vel:100, time:(Rat 1/4))
info: not stopping, not playing now: (NoteOffEvent, pitch:52, vel:100, time:(Rat 1/2))
info: ignoring duplicate tone: (NoteOnEvent, pitch:55, vel:100, time:(Rat 1/2))
info: not stopping, not playing now: (NoteOffEvent, pitch:55, vel:100, time:(Rat 5/8))
midiplay: /dev/music: Device busy


gnu-solfege is configured to use timidity, this program is installed from pkgsrc too.

I would like to know if this behaviour is normal or if I missconfigured something.

If I try to use /dev/audio I get this error message in GUI: 
"No module named _solfege_c_midi"
 
So use direct audio is impossible with this program too. Is there a way to use 
gnu-solfege in NetBSD ?


>How-To-Repeat:
Install timidity and solfege from pkgsrc. Launch solfege from command line.
Try to use solfege and get message about _solfege_c_midi module
Try to use external program for midi and get i:
"/dev/music Device Busy message" on std output
