I found that lilypond did slurs surprisingly well and
dynamics somewhat in 1.4.13, but
the dynamics were not very satisfactory. I suspect that
the cause of that is two voices on one staff, but playing
with the defaults might help too.
Q. Is it possible to override the default velocity values
in the .ly file? I think many compositions might profit
from a rehash in the working directory. Can that be done?
Midi doesn't handle unisons very well. If midiInstrment were
voice instead of staff context, it might be better, and
it would be possible to get harmonics, for example. Until
the happy day that that is fixed, the hack is to
copy your working directory's contents and make a midi
producing version of your file with each voice on a
separate staff. You might even prefer to work that
way. Your midi version of your .ly file
can also have different dynamics for each voice, which
might look rather strange in your printed version.
Of course it is extremely advisable
that each piece have its own directory anyway, so you
would copy ~/lily/yourpiece/* to ~/lily/yourpiece-midi/
I hope that access to the drum patches will soon be less arcane.
All that remains is a way of including the lyrics, to make a
.kar file, and a way of writing to the header fields of
the midi file for copyright notice, etc., and lilypond
will be a formidable midi sequencer.

I think many will change their minds when they start
using an exterior file to produce the notes. Then
every .ly file becomes a template and the default .ly
file merely a receptacle.

It is a good thing. Denemo, too.
