There is much to digest in this thread. However, your last post, Scott, I think I understand what you posted but... I really don't know if I can press one of those buttons around the screen fast enough. Maybe I can. But sometimes, there is almost no time. I can barely jab at a button. Maybe I should change my music.

The Registration buttons are, by far, the most accessible, being very close the right hand as I play. I need to digest all of this to see if I can figure out how to do this with Registration buttons.

Actually, I'll try what you said a few times.
