Hey there!
There are at least three ways to enter polyphonic percussion music (see
examples below). However the first (easiest) approach does not produce any Midi
output in polyphonic parts.
% first example - no midi output starting from bar 2
\version "2.14.2"
\score {
\new DrumStaff <<
\drummode {
bd4 sn4 bd4 sn4
<< {
\repeat unfold 16 hh16
} \\ {
bd4 sn4 bd4 sn4
} >>
}
>>
\midi { }
\layout { }
}
% second example - no problem here
\version "2.14.2"
\score {
\new DrumStaff
\new DrumVoice {
\drummode {
bd4 sn4 bd4 sn4
<<
{
\voiceOne
\repeat unfold 16 hh16
}
\new DrumVoice {
\voiceTwo
bd4 sn4 bd4 sn4
}
>>
}
}
\midi { }
\layout { }
}
% third example - no problem here
\version "2.14.2"
\score {
\new DrumStaff <<
\new DrumVoice {
\drummode {
\oneVoice
bd4 sn4 bd4 sn4
\voiceOne
\repeat unfold 16 hh16
}
}
\new DrumVoice {
\drummode {
\voiceTwo
s1 bd4 sn4 bd4 sn4
}
}
>>
\midi { }
\layout { }
}
