PITCHSHIFT - DDL
PitchShift-DDL combines a pitch shifter with a digital delay. PitchShift-DDL uses a continual
crossfading technique of pitch shifting. This technique maintains the stereo field exactly. Of the
one unit pitch shifters, this one works best for large pitch shift ratios, in some circumstances.
Another feature of this algorithm is a digital delay that feeds back into the pitch shift. This
feature allows spiraling upward or downward pitch shifts.

01 — Mix
02 — Volume
See the descriptions under the Mix and Volume Parameters earlier in this section. This algorithm
sounds best with a Mix of wet and dry. Try using a modulation controller for the Mix parameter
to fade in or fade out the pitch shifted signal.
03 — PitchShift Vc 1 Semi Range: -12 to +12
Adjusts the pitch of Voice 1 up to an octave above or below the original pitch in semi-tones.
04 — PitchShift Vc 1 Fine Range: -99 to +99
This parameter allows you to fine tune the pitch of Voice 1.
05 — PitchShift Vc 1 Level Range: 00 to 99
This parameter adjusts the volume of Voice 1.
06 — 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. This is actually a balance control which determines how much of the
left and right inputs will be fed to Vc1.
07 — PitchShift Vc 2 Semi Range: -12 to +12
Allows you to adjust the pitch of Voice 2 up to an octave above or below the original pitch in
semi-tones.
