Understood...
Check out the Tone and Drum Kit list, though. It's got a TON more sounds and kits. BK-5: 1,172 tones, 60 Drum Sets, BK-9 1,718 Tones, 77 Drum Kits.
And a bunch of those extra kits are from the SRX board... Tasty! Not to mention, for the first time EVER in a Roland arranger (I think), drum roll please...................
USER Drum Kits! ANY sound on ANY note!
Want that mirror layout from the Kurzweil's? No problem! (Anybody ever program drums on a Kurzweil? They have a non GM layout where the sounds are mirrored so LH and RH can play them all without getting tangled up - God, I wish GM had gone with that!)
Naturally, one SHOULD expect a lot more from a keyboard that is double the price. Trust me, Fran, it delivers. I played the BK-5 and wasn't really impressed. BK-9 impresses the hell out of me.
Hope the gigs start coming in again...
