Randy, I knew there was a workaround using the assignment buttons, but I didn't get that far in the short time I had to work with the keyboard.
My friend, Helmut, called me this morning and said I should buy the SX-900 so I could post lessons on the PSR-Tutorial and Synthzone on how to use all the features. I turned him down - just one more thing for the kids to sell after my untimely demise.
