Compound Time Subdivision Fix

Bagpipes in all their many versions play 6 9 12 15 and 18 / 8 time signatures need as a subdivision showing three eight notes which for us is one beat. So a 6/8 would have two three eight notes making one beat.for a total in the measure of two beats. A 9/ 8 would have 3 beats and have three three eight note sections. A 12/8 would have 4. 15/8 5. Ect Can't use ure app for this feature when we play right now. We call the compound time. Just add the fix to the subdivision.

Merged into "App: Add subdivision to improve support for bagpipes" #692
