hello, i bought the roland a88 mk2 this monday (cannot test it in store, i bought it because the top is flat so i can slide it under the desk) , i had the NI S88MK2 (the action was ok , a bit sluggish but ok), i had the SL88 grand Great great action but i can't put it under my desk (the joystick on top and the big knob next to the screen) , i had the casio PX5S (cool too but same problem modwheel on top , can't slide under my desk)...but now..i have a problem with the roland a88 , i like it because i like the joystick placmeent in bottom left, i like it because it s silent, the fake ivory make it not slippy BUT it's a bit too heavy my right hand is tired after 5 minutes...(i have an yamaha acoustic piano and the yamaha is really lighter on touch)...so now i'm lost..what would be your advice? is there a 88 midi keyboard that is fast /responsive/silent/not too heavy or do you some finger or hand workout i can do? (i'm thinking about a doepfer or the kurweil km88..maybe the m-audio hammer 88, but i don't like the m-audio brand)
