I don't understand the question. You can transpose both printed and
MIDI output with \transpose, and you can transpose the MIDI separately
using \property Staff.transposing. (see the reference manual.)

I would enter the music in the way that you read and process it;
that's the easiest thing for verifying what you've entered. Then you
can use \transpose to produce parts to your orchestra's liking. Using
the transposing property, you can get a MIDI file that sounds OK.

BTW, Real French Horn Players don't care wether it's in F or not, they
Just Transpose.

again, this sounds as if Staff.transposing would solve your problems.

BTW, I don't know about denemo, and perhaps you get better answers if
you ask around on the denemo mailing list. See

Happy Easter!
