How do I assign rhythm kits to parts other than 10?
1) Press MIXER.
2) Press F2- Part View. Here you'll see a list of all sixteen parts used within your performance. Part 10 is, by default, your drum part.
3) Note the area containing the little "R" to the left of part 10. Cursor to this same area on any other part.
4) Turn the VALUE DIAL once to the right so that you see the "R" for that part. You've now turned this patch part into a rhythm part.
