And the action is very nice, despite not being my G70's action.

The keys are about 1/2" shorter than the G70's (by comparison, a full sized piano key is 1/4" longer than the G70's) but only 1/8" shorter than say a Korg Triton.

Width is standard (13" for 2 octaves) the same as regular pianos and most everything 'normal' sized.

I find the action very crisp and precise, comfortable on key-down, with none of the sponginess from the BK-5/3 in the springing. Mind you, even the BK-5/3 are MUCH better than the PSR action on the S950 (yes, I've played one!). Can't for the life of me understand how a $2000 keyboard can feel that bad!

All in all, I can play very comfortably on this keybed (the BK-9's). No, it isn't QUITE as good as the G70's, and it does have a piano style 'lip', so palm smears run the risk of snagging a little bit more than the G70 (but side to side stability is very good, no play, so so far this isn't an issue - organ playing is very comfortable), and sadly, no aftertouch... (I still don't understand why Roland cut THAT corner!) but all in all, I am very pleasantly surprised.

I have a friend with a PA3X61, and it compares quite well to that. You guys know how picky I am about actions... I wouldn't be endorsing this one if it didn't meet my needs.

I am content.
