I would also be in favor of a "pitchfactor".
At the least it should do the basic whammy things as mentioned above which would let me retire the whammy pedal, and also basic Octave pedal type stuff one octave below and 2 octaves belows and let me adjust the level of each…
On top of that it seems that it should be able to generate atleast 2 harmonies at whatever desired intervals, perhaps even in 1/4 step increments to give you some capabilities to greate absolutely grotesque sounds.
