Musink supports grace notes, which are also known as flams or ruffs in percussion.
To add grace notes to a note:
Most marks can be added to grace notes, just as they can be added to normal notes. The exception are slurs: one slur per grace note group is automatically added when you create the grace note. This can be deleted in the normal way. You cannot add ties or slurs to grace notes yourself. If you wish to add a slur because you deleted it by accident, delete the grace note and add a new one.
Marks added to grace notes are proportionally smaller, to match the size of the grace note itself.
Grace notes are played back as 32nd notes before their parent note.
