I've seen you do that in some of your Root Doctor vids, how do you play a Rhodes (or any kind of piano sound for that matter) on a Hammond action? That would drive me nuts.
That said, for synth sounds the Clonewheel + Rackmount would certainly do the trick. However if your bottom board is a ROMpler already, you might be better of with just a synth rackmount, NL2 Rack for example.
Very true. Compact is right on the money, but I can't blame you for being hesitant to buy it before Nord updates the damn thing thing to allow samples. Why the NE3 is more powerful than their flagship model I have no idea.
