Thanks - I don't thin there is an "avoid transpositions" on the Mac version. But even if there were, if you are raising or lowering a key by one or two steps it would probably play out-of-key. I think I will bring the RT into Pro Tools and see if I can't bump it with Elastic Audio. It may also be able to be done in GarageBand 2015. I am pretty sure it can be done in Logic Pro X which I am moving to because AVID has not updated the driver for my MBox3. I m thinking the Apogee Ensemble and Logic make great companions.
