The Pitch Fork will NOT do what you’re asking. The Slammi Plus WILL do what you’re asking in Dual Mode with Cross Fade.

On the Pitch Fork an expression pedal works two ways depending on the “Latch” setting. If latch is enabled, then the expression pedal controls the pitch with heel down being no pitch shift to tow down being full pitch shift. The pitch can go up, down, or both simultaneously up to three octaves, but heel down is always no pitch shift.

If latch is disabled, then the expression pedal controls the speed of the automatic glissando activated by the switch on the pedal. This still would not give you what you want.

The Slammi Plus is like a Pitch Fork with a built-in expression pedal and several extra and important features. It has the same up/down/both ranges as the Pitch Fork, but it has a cross fade function that allows you to fade between two different pitches without glissando. You can select a heel pitch which can be dry (no pitch shift) or anywhere from -1 octave to +1 octave, and a toe pitch which can be anywhere from -3 to +3 octaves. The pitches remain fixed and you cross fade between them by rocking the pedal.

So, to do what you need, you would set it to Cross Fade, Heel = -1 Octave, Toe = +2 Octaves. You would start on the heel, and rock to the toe for the bridge.

As far as I know, the Slammi Plus is the only pitch shifting effects pedal from any manufacturer that can do this.
