PITCHSHIFT - DOL
00
-
PitchShift-DDL
combines a pitch shifter with a digital delay. PitchShift-DDL
uses
a
continual crossfading
tedmique
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
which
feeds
back
into
the
pitch
shift. This feature allows spiraling
upward
or
downward
pitch shifts.

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 this
parameter
to
fade
in
or
fade
out
the
pitch shifted signal.
03 - PitchShift Vc 1 Semi Range: -12 to +12
This
parameter
allows
you
to adjust 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
This
parameter
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.
07 - PitchShift Vc 2 Semi
Range: -12 to +12
This
parameter
allows
you
to adjust the pitch of Voice 2
up
to
an
octave above
or
below
the
original
pitch
in
semi-tones.
