Looking for a way of randomizing a continuous MIDI signal into the midi input on my Whammy Pedal to generate random pitch shifts.
Well, one way is to get a Molten MIDI box; it's a little box that sends patterns of CC's to your Whammy to make it do interesting pitch-shifty things. You can even program your own patterns. It's pretty neat. Another way would be to draw a CC pattern in your DAW like Ableton and then send that out your MIDI interface to the Whammy.
Also, in Ableton you can use it's midi effects to create a real random effect (I'm not sure if it is a truly never repeating algorithm, but it will do). Using the velocity effect, there is a random setting, if you set it to 100%, you will get midi data from 0 to 127, variating with each hit I've also experimented with stringing different arps in parallel and series to make up certain patterns that take a long time before playing exactly the same. But the cool thing is that you can write these midi notes to a new midi-track, which you can then re-use as new input for the same procedure. And, so with some thinkering you might get a midi-stream for your Whammy that will blow your socks off ;-)
