For me, the patch remain feature (as mentioned by Fran) is a must on an arranger. I thought my Tyros 2 was not properly programmed as this feature is impossible on it, but this is the way Yamaha approaches keyboards (you can see my post asking help on
http://www.synthzone.com/ubbs/Forum37/HTML/015786.html). Other significant feature I've found on my G-70 as well, is the ability to use Make Up Tools to edit styles up to the drum instruments to be used (terrific feature).
I hope Yamaha will keep the multi pads and the use of folders to save own settings (registrations, styles, songs, etc.) on future arrangers.
My 2 cents...
