Oh yeah... Not sure if its been mentioned but..
The Roger Linn Addrenalinn has got programmable pitch shifting sequencing abilites, and will sync with midi clock. And its a pedal. So that will do the whole Whammy / sequencer thing without the computers.
Its also got all sorts of step flanges, step filters, and various other forms of step.
I bet it can nail the effect. Maybe one day I will play around with mine.
