Hey, Irecently acquired a Rocktron Intellifex rackmount effects processor. It does not have a midi control unit. I know that the Rocktron Midimate will work with it and even run off the phantom power jack in the back of the intellifex (if you have a seven hole midi cable. My question is will other Midi control device work with this unit, and if so will they work with the phantom power? Thanks.
