Re: Lilypond's English Horn MIDI instrument is non-transposing?

[Valentin Petzel]

That is not in fact worded correctly. The midi standard allows a midi 
controller to specify a program to the midi synthesizer, which is a number in 
0-127 and is intended to allow for switching between different sounds (although 
it is in fact the decision of the synthesizer what to do with that).

The General Midi standard then defines a specific map of these program numbers 
to certain instruments. So any GM compatible synthesizer needs to provide 
these instruments in this order.

Lilypond uses these GM names, which makes Lilypond a somewhat GM compatible 
source. This means that as long as we use a GM compatible synth everything 
should have the right sound.

Cheers,
Valentin
