Limitations:

Aftertouch pressure and miscellaneous MIDI events are not recorded.
Instrument is assumed to be piano at start of each recording. If you want to keep playing with a different instrument, change the instrument and change it back to send an instrument change event.
Instrument names may not always match what's shown on your device. Some pianos include voices outside of the GM / GM2 / GS / XG standards. You may want to note the voices used in the file name.
Only one channel is supported, so split/dual instrument settings won't work.
Pitch bend range is assumed to be ± 2 semitones (a common default).
