Hello all, In the following, the two aftergraces do not align.
The 15/16 in \afterGrace 15/16 … is not a duration but a fraction of the duration of the following note. In the upper staff you have a half note, in the lower staff a quarter note. To align the grace notes, you’ll need 31/32 in the upper or 7/8 in the lower staff.
