Yes. But it doesn't give the result I'm looking for. It's _looks_ like
the wanted engraving, but it's not perfect. It's a slightly different
concept than tremolos.
Rolls are denoted with 3 strokes.
Ruffs are denoted with 2
The strokes across the stem is usually more light than a tremolo.
This gives a nicer looking roll:
\property Voice.StemTremolo \set #'beam-thickness = #0.1
\property Voice.StemTremolo \set #'beam-width = #1.5
\clef percussion
sn4:32( sn8) r8
However... when I try that with ruffs, the strokes align to the beam and
becomes horizontal when the beam is. That's not the intention.
\property Voice.StemTremolo \set #'beam-thickness = #0.1
\property Voice.StemTremolo \set #'beam-width = #1.5
c8:32~c8
Rolls generally a just drum rolls lasting as long as the note. No one is
counting how many times the stick hits the snare.
Ruffs are (most often) 5 beats (the 5th being the tied note). In the
above code there will only be 3 beats.
For the MIDI output, it's possible to unfold tremolo repeats
as shown in
http://lilypond.org/doc/v2.2/input/regression/out-www/collated-files.html#repeat-unfold-tremolo.ly
See also the mailing list archives, where a related question was
answered earlier today.
I've read about unfolding tremolos and I've found mails on the list
about it. It's not what I want though.
I've only found one thread about marching band snare drum notation and
it was about the stroked grace-notes used to represent using both sticks
with a small offset (a "slip" in Danish). I have no problem with them
though.
