Hi! Read the entire post because I also provide a workaround.
The problem:
The note position should be rounded up (i.e., display quantized to
30.1.1.0
), but it’s not.
The workarond:
1. Move the note to the 30.1.1.0
position (quantize it).
2. Open the Score Editor and convert the note to a grace note.
3. Open the Key Editor and bring the note back where it was.
Result → Now the note is displayed (problem solved!) and also sounds as it should!
