I haven't made extensive tests, but it seems the << {..} \\ {...} >>
construct is incompatible with midi (drum?) output. If you
rearrange your score to use explicitly defined DrumVoice contexts it
should work. Something like this:
musicOne = \drummode {
\repeat unfold 8 { cymr8 }
}
musicTwo = \drummode {
bd8 bd8 bd4 bd8 bd8 bd4
}
\score {
\new DrumStaff <<
\new DrumVoice {
\voiceOne
\musicOne
}
\new DrumVoice {
\voiceTwo
\musicTwo
}
>>
\layout { }
\midi { }
}
I'll add this limitation to the Notation Reference after I've
checked further (or if someone else confirms it before I find the
time to check it).

Subject: Midi-output not generated
Hi there,
I have the following drum excersises written out for my daughter.
It prints
beautifully (except that I am not able to set the vertical spacing
to my
linking, but that's not that big of a problem). I just wonder why
the
midi-file (which is generated) only is 149 bytes long and contains
no sound.
Dows anybody know what's going wrong? There are no errors or
warnings in the
log.
