Yes, JMax is a visual composition tool, with little boxes
sending signals to other boxes.

As for ALSA, it seems very general in GNU/Linux, actually kernels >=2.5.x 
include ALSA modules, thus it seems a companion of choice on that
plateform.

What is about, here, is typically playing a single note at the time we
insert it, in Emacs, or playing a region of notes, for proof reading,
not the playback of a whole piece: the midi generation is of course
delayed to lilypond.

Actually, what has been written so far is a 100 line piece of code,
which bravely does its job :) but you're right. I'll look at TSE3,
which seems to offer the "generality" in terms of backends discussed
above (ALSA, OSS, ...) It may be a good idea.

Indeed. François has code for using external MIDI devices. If we
manage to merge our works, on a genericity basis, other software synth
could be used also...
