Pondering over which arranger to purchase, I have concerns that the 7000 might be too steep a learning curve for me. Questions:
1. Is the sd card and all it offers easily understood?
2. Can I get by WITHOUT having to use a computer (which I really dont' want to do)

Given the fact that I have past knowledge of sequencing with keyboards (but no software knowledge) and familiar with operating systems in the PSR 2000 series, etc. and some brains, will I catch on fairly easy coming from the Yamaha format? I realize this is a broad question, but comments are appreciated because I really do like this board.
Thanks,
Zuki
