This is part of the problem with the "pared down snippet" approach, or 
rather, my original explanation of the problem. In reality, my problem 
is more complicated. I am attempting to create a "practice book" for 
various brass/woodwind instruments, so:

 + I have an exercise that goes through 12 keys: c-cis-d...bes-b

 + I want to use a single source for transposition to 3 keys: c, d, and 
a (essentially concert, bes, and ees). The exercise are identical apart 
from the key (the backing track is at a fixed pitch and I don't have 
the ability to change it in any meaningful way).

Unfortunately, I suspect I am going to need to create a separate 
edition for each transposition, but I hoped there would be a short cut.

Thank you!
