Bug description

When exporting a piece that uses acciacciaturas (quick grace notes) to MIDI, they are converted to something that sounds like appoggiatura.

Steps to reproduce
  1. Write a piece that uses acciacciaturas.
  2. Export to MIDI
  3. Play it back, it should give a wrong conversion.
Screenshots/Screen recordings

I write two bars, one with acciacciaturas and the next one with appoggiaturas. The first playback sounds exactly as it should.
