That's normal behaviour and dependent on the number of notes of
polyphony set at compile time ( haven't a clue what the default is) and
the release time of the notes.

Looks even more like a straight MIDI problem.

Say you have a poem and I have a tune.
Exchange them and we can both have a poem, a tune, and a song.
