MIDI file not played correctly on Kawai CN37 piano
This is a little obscure, but:
The attached MIDI file is the last few bars of Muszynski flute duet Op. 34 no. 1. I exported it muting the upper voice (flute 1) so that I can play with the lower voice ("music minus one" style). The Kawai CN37 piano plays everything correctly through the quarter note E in measure 4. It then cuts off abruptly and does not play the tied half note in the last measure. If the procedure is repeated but without muting, it plays everything correctly. Windows Media Player plays correctly, regardless of muting. This seems to point to the piano as the source of the problem, but it might occur with other MIDI instruments; I don't have any for comparison.
For reference, the attached files are:
test_case.mscz = the original MuseScore file
test_case.mid = exported with both voices active
test_case m.mid = exported with upper voice muted.
