I am sure a lot of piano players will welcome the 88 note hammer action.
As a more of synth/keyboard guy i don't really want hammer action but I certainly would like 88 keys, or 76 as a minimum. 61 note boards just do not have enough notes, and its not just about instrument range, I have to use a small AKAI mini keyboard for key switches along side my A-PRO 800. I have many Kontakt libraries that need more that 61 keys just to access the instrument range and keyswitches.
