it's a VERY nice board. if you can think of it, you can get it done with this one keyboard.
but why spend $8000 on ONE piece of equipment??
you could build a very nice home studio for that amount of money. a new pc or mac, an 88 key controller, mics, pro tools, and the right kind of software for whatever it is you do will run you about the same amount of $$...maybe even less if you catch deals.
not a practical buy. just my opinion though...
