I'm not sure I want to pay for all of those editing options. I tend to be a player, and my days of editing went out with the DX7.
However, the Kronos is quite a beautifully sounding instrument, although Nedim's sound editing demonstration was rather too simplistic to be of any benefit, at least to me.
Most arranger keyboards, from all brands, have enough sound editing for 99% of a "player's" needs, in my opinion.
