I'm writing the percussion music for our marching show this year. I have our very tiny battery on drums for the 1st and 3rd movements of the show. For the second movement I want to switch instruments for all of them and have them up front playing hand drums, cymbals, etc. My questions are as follows: 1. How do I add 4 other instruments to the score in place of the bass drum line for only the second movement? 2. How do I get the template to allow for the correct input mapping of the new instruments and then switch back at the appropriate location in the music? 3. How do I get it all to play back correctly? Meaning that one part is snare drum, switches to hi-hat, and then back to snare again and those instruments are what I hear.
