My Whammy V is rackmounted and will be controlled via an RJM Mastermind GT22 Midi Controller. i'll be using an expression pedal to control the sweep. I also need an expression pedal to control my chop tremolo rate and I'm trying to determine a way to use a single expression pedal for both effects. The Mastermind allows me to program any expression pedal to control 2 different effects (so I don't require a special expression pedal that has 2 outputs neccesarily). The one thing I'm not sure about is how to program it for situations when both the whammy and trem are on at the same time and I only want expression on one of the effects. For example, I often like to have the whammy set to octave down, and use chop trem with expression without the expression pedal changing the whammy position (octave down would be toe down). Any ideas?
