Thanks for the tips.
I have done those very things with General Midi files, but I have yet to convert a GM file to a GEM block (can you believe it?).
So if I was to take a GM file with all the extras added via Cakewalk, load them into RAM of the keyboard, and save them as a Block, all the goodies would be there, right? When I think of all the GM midi files that I've loaded into my board (1500+) and I've never tried to save them as Blocks...I shake my head.
Thanks again for the tips.
