You could use http://electronicmusic.wikia.com/wiki/System_exclusive or you
could send events using another protocol than MIDI.
MuseScore embeds an OSC server, it doesn't send OSC message during playback
but it could. OSC might be a lot more flexible than MIDI for your purpose
(but I guess it would mean your arduino has an ethernet shield and can
handle UDP, and you mentioned serial...). Ideally, I would love if this can
be made general enough to drive any other external devices/programs during
playback. The SSMN project wanted to drive a 3D audio system in sync with
the score https://blog.zhdk.ch/ssmn/faq/
Even if using MIDI, it would be cool to make it larger than just Piano
Tutor. There is probably other use case that would benefit sending more,
configurable, MIDI metadata.
