changing the midi instrument; broken

[Ted Walther]

I am running Debian unstable, with lilypond 2.6.3 for typesetting,
timidity 2.13.2 to play midi files, and freepats 20060219 to provide the
midi patchsets.

I notice in the manual it says the patch set has to be named exactly,
with no variance in case allowed.  So I have been pasting in different
instrument strings from the manual, trying to get something other than
grand piano.  I have not had any fortune.

Does anyone else have a similar setup to mine, and have they succeeded
in making a midi file that does not come out using the grand piano?  Is
this a lilypond bug or should I harass the timidity and freepats
maintainers?

I am using the following line:

\set Staff.midiInstrument = #"oboe"

I have tried it in the top level, and inside a \score section.  It makes
no difference; the resulting midi file always uses the default grand
piano.

You can see the input file I am using here:
