Most but the blinkered and blind don't give a toss what name and logo is on the panel... Sound and capability is all anyone should care about.

Were Casio to make something I wanted, heck, were Lionstracs to make something I wanted ( ), I would buy it regardless of prior product.

Thing is, genesys, in this economy, biting off more than anyone can chew is going to go down in flames. You can't honestly expect that gargantuan wishlist of features to come out at a price anyone can afford, do you?

Baby steps, man, baby steps. Combine them ALL into an über-product later, when the crash is over... Perfect each component NOW, assemble them when we can all afford them afterward.

But I still think, as ARRANGER players, an MPC type product (which is what you describe) will float like a lead balloon (we already GOT arrangers, you see). And yes, were Casio to unveil what I actually WANT, I will drop ANYTHING in a flash... as long as I can afford it. So, there's at least ONE 'hands up'!
