So I have been learning the 970 and relearning Yamaha conventions....this is a great instrument with a few quirks. the arpeggiator helps a ton with energy and variation....and the sounds are uniformly great. wish it had a better selection of EPs but the Concert Grand is at least useable.
One quirk is the audio recorder -- it's very fussy about thumb drives. went through about 6 (including 2 brand new ones) before I found a SanDisc that it could get along with. (kept getting an error msg saying "Audio Recorder is temporarily unavailable" in the middle of recording!)

my next hurdle is to transfer a set of multipads from Korg to the Yamaha. is this possible? I'd appreciate any/all insights.

thank you.
