In the pitchflex mode, the pitch is the default expression control. Is there a way Eventide could allow us to unassign the pitchflex and allow OTHER parameters to be controlled? For instance: I like the filter control in the pitchflex mode. With some fuzz in front of the pitch factor, the filter sweep can be some what "synth" like. I'd very much like to be able to have a preset where just the filter is controlled with the expression pedal and the pitch shift disabled.
