Hi, first off I have the original Mastermind, and just bought a Nektar $20 expression, just because eventually I will get a Mission expression, perhaps next year, but wanted to futz with this thing. I don't remember ever seeing how the expression can be set up, I know you sent me a link about getting my fx2000 to be able to have the effects switch with the rack gizmo and the buttons on the mastermind, but very very curious on how to set it up with the mastermind. On a side note, in the future, if I get a mission sp1 RJM expression, and then an expressionator, would that all be compatible with the original Mastermind? Anyways, thanks.
