If you say "overlap is the one synthesizers recognize": does that mean
that there needs to be a physical gap, or is it sufficient if the
note-on command of the next note comes before the note-off command of
the previous note in the MIDI data, without any intervening time gap?
That would probably make it easy to decide on an output (apart from
slurred identical notes which already provide a conundrum for the
player) while probably making it non-trivial to code.
