I know C++, LISP and TeX, so maybe... If I find the time.
Lack of proper snare drum notation is problem with most music notation
programs out there. My GUI/Windows using colleagues are also struggling.
Rolls are denoted with 3 strokes.
Ruffs are denoted with 2
Like c8:16 versus c8:32 ? Or did you mean the 2 strokes in addition to
the beam like in c'8 [ r c8:32] ?
2 strokes in addition to any beams. Like in the example. Notice how the
strokes are not parallel to the beam.
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.
In the MIDI output, you mean?
Yeah... well. In the mind of the drummer anyway :)
Ruffs are 5 beats (two right sticks, two lefts sticks and a right to end
the ruff). There's something called double-ruffs, but I'm not a drummer
Rolls are just a maintained series of beats for the duration of the
note. Of course MIDI has to know the numbers of beats, but the drummer
is usually not counting, and for slow tempo you would get to few beats
for the roll to sound right.
I've read about unfolding tremolos and I've found mails on the list
about it. It's not what I want though.
In what sense?
I can live with rolls being expanded as :32 tremolos to midi. Mostly it
gives the correct result (for standard marching tempo). With a little
tweaking it also gives the correct print.
Ruffs however are a problem. :16 tremolos are too slow and only give the
correct number of beats when used on a quarter-note (which is not the
case in the example I gave ("Liberty Bell"). Also the print aligns the
strokes to the beam. The beam and strokes should not be related.
