Unintelligible MIDI output

[Marcelo Gomes de Queiroz]

Hello!

I have been struggling the past few weeks with an example 
that produced a very odd MIDI output. Unfortunately it is
an awfully large orchestral example, and I can't reproduce
it with a small file. The main file is orchestra.ly. The
music lasts for about 4 minutes and 40 seconds. The midi 
output has events up to 40 minutes, several notes without 
'note-offs' and other strange things. On aplying timidity 
to it I got, among other messages:

> orchestra.midi: Can't read track header.
> Drum set 7 is undefined
> Drum set 127 is undefined
> Instrument `pistol' can't be found.
> Couldn't load instrument pistol (tone bank 0, program 127)

but the music has no pistols nor drums. I'm using 
Lilypond 2.0.0. I had the same problem with 1.6.6. The
example files are tgz-ipped. 

I think it has something to do with MIDI limitations on 
number of tracks, because when I try less than 16 staves
everything works fine. The fact that Lilypond didn't 
report anything wrong on producing the wrong midi file 
made me think it might be considered a bug.

By the way, I tried to find in the internals documentation 
any hint on telling Lilypond to use a specific midi track 
for a particular Staff (since my example has 34 staves but
uses only 13 "midi instruments"). I guess I shouldn't mix
a question with a bug report... sorry! But if you could
help me...........

Thanks in advance!
