FAST PITCH SHIFT
FastPitchShift has a transport delay of only 10 msec and a maximum detune ratio of one
semitone. Try shifting the voices slightly in both positive and negative values (parameters 03 and
06) to create a fat sound. This algorithm can be used for pitch correction (for instance, try
hooking up a mod wheel for MIDI).
01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters, in the beginning of this section. This
algorithm sounds 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 Fine Range: -99 to +99
This parameter allows you to fine tune the pitch of Voice 1.
04 — PitchShifter Vc 1 Level Range: 00 to 99
Adjusts the volume of Voice 1. A setting of 00 would eliminate any audible pitch shift.
05 — PitchShifter Vc 1 Pan Range: -99 to +99
Allows you to assign the location of Voice 1 in the stereo field. A value of -99 would be far left,
and +99 would be far right.
06 — PitchShifter Vc 2 Fine Range: -99 to +99
This parameter allows you to fine tune the pitch of Voice 2.
07 — PitchShifter Vc 2 Level Range: 00 to 99
Adjusts the volume of Voice 2. A setting of 00 would eliminate any audible pitch shift.
08 — PitchShifter Vc 2 Pan Range: -99 to +99
This parameter allows you to assign the location of Voice 2 in the stereo field. A value of -99
would be far left, and +99 would be far right.
09 — PitchShifter LFO Rate Range: 00 to 99
Controls the rate of pitch modulation which creates a chorusing effect. To achieve chorusing, this
rate must be very low.
10 — PitchShifter LFO Width Range: 00 to 99
Controls the excursion (amount) of pitch modulation. Since the rate is usually very low, then the
width is usually very large.
