I've fixed the problem a better way, now you get the instrument names as
they are in the sound font you have selected and LilyPond emits the
correct program number by being told the GM instrument name. You will
then hear the correct instrument in the Playback View (because Denemo
has set up the synthesizer, not LilyPond).
The only wrinkle is the Channels synch between Denemo and LilyPond, (see
previous email). Default is ok, but if people want to get the most out
of MIDI they will want to tell LilyPond to use one channel per
instrument (e.g. left and right hand of piano) and will then need to
adjust the channels in Denemo to match what LilyPond does.
