PITCH SHIFT 2U
Pitch Shifters allow you to change the pitch of a signal to any pitch desired within a range of one
octave in either direction. Pitch Shift 2U is a splicer-type incorporating zero crossing detection.
Pitch Shift 2U has incorporated one ESP chip for zero crossing (pitch) detection for splice
synchronization, having an optimal detection range of 55 to 555Hz. Splicer type pitch shifters are
popular because for low pitch shift ratios, splicing is infrequent. These pitch shifters can create
very interesting stereo fields — by panning each of two pitch shifted voices selectively, and because
of the inherent time delay modulation of the algorithm. Pitch Shift 2U takes the left channel input
as Voice 1, and the right channel input as voice 2.

01 — Mix

See the descriptions under the Mix and Volume Parameters, in the beginning of this section.
These algorithms sound best with a Mix of wet and dry. Try using a modulation controller for
the Mix parameter to bring in or fade out the pitch shifted signal.
03 — PitchShifter Vc 1 Semi Range: -12 to +12
Allows you to adjust the pitch of Voice 1 up to an octave above or below the original pitch in
semi-tones (half steps).
04 — PitchShifter Vc 1 Fine Range: -99 to +99
This parameter allows you to fine tune the pitch of Voice 1.
05 — PitchShifter Vc 1 Level Range: 00 to 99
Adjusts the volume of Voice 1. A setting of 00 would eliminate any audible pitch shift.
