Now it gets a bit complicated. If you make an instrument in LMMS
respond to all channels ("--" in the MIDI channel selector) it won't
keep track of which notes came in on which channel... which would be
needed for your keyboard to work. With my changes you'll get too much
release instead of too little.
A little more googling gave me this:
http://www.philrees.co.uk/articles/midimode.htm#mess which hints
strongly that All Notes Off shouldn't even be recognized in that
situation (Omni mode being the closest in MIDI terms). Think I'll do
some reading and refine the code.
OTOH, everything is fine (and now a little bit better) for keyboards
sending on only one channel.
