Also CindyG, I believe several dedicated buttons were removed and replaced by pressing the Direct Access + Voice , or in your case Direct Access + R1, assuming the voice is located in the R1 part. Can someone verify this for me?
For example, when I set up my R1, R2, and R3 voices, I may want to change the octave range for one part. The only way I can see how to do it is to press Direct Access + Upper Octave. There's probably another way, but my way seems the fastest.
