Not on *my* MIDI synthesizer. Two notes are two notes! I'm inclined to
be concerned by this because I do a lot of doubling of notes between
different MIDI channels. Each channel plays on a different patch, or in a
separate monophonic recording run on the same patch, and a doubled note is
quite different from a louder note.
If LilyPond were to start automatically deleting notes because someone
think's it's a bug for unisons to exist between MIDI tracks, it would make
the pile of workarounds I already need to use to get decent MIDI out of
LilyPond, that much worse.
Well, I didn't say it was a bug, and surely two MIDI tracks should normally play two notes, especially if they are different instruments. But I'm talking about a specific piano performance technique. When two voices (hands) have the same note written, the pianist doesn't play the same note with both hands. Instead they pick a hand to play the note and leave the note out of the other hand. This is why I suggested that the MIDI performer could ignore \parenthesize notes. Would this create a pile of workarounds for you?
