If you can direct me to a guide to assigning grace notes to music without grace notes I will happily consult it.
Incidentally, I do use grace notes in this piece. Perhaps they are difficult to hear with the accompanying instruments.
You can start here, but do not be afraid to get a practice chanter and take a few bagpipe lessons, you will be very glad you did:

You can hear the off side strikes of the keys on the grace notes listen carefully !
