Bank 8: the Pitch Change and Doppler Programs
Page Three
MIDI (MIDI Pitch Event Left)
MIDI Pitch Event provides a fast link between a MIDI
Note Event and interval pitch shifting. By establishing
a patch with NOTE EVENT as source and PITCH
EVENT as destination, the amount of pitch shift can
track incoming notes in semitone intervals. Pressing
the KEY will tell you the curent pitch shift.
REF (Reference MIDI Note Left)
REF sets the MIDI Note Value for no pitch change,
NULL + 0C, when under MIDI control.
MIR (Pitch Mirror Left)
MIR selects the direction of MIDI pitch control. When
MIR is ON, pitch is shifted down for increasing note
values.
GLL (Glide Stereo/Left)
GLL affects both channels in stereo mode, and the left
channel in mono mode. It changes the pitch continuously
over a range of + one octave. This allows a
glissando to be performed, either manually with the
LARC, or via MIDI. The full resolution of the pitch shift
is not available on this control, although vernier (fine
tuning) is available by pressing the button under the
slider twice.
SPL (Splice Length)
SPL sets the amount of time the splice takes to complete.
It is only active at moderate values of pitch shift.
Very short splices produce less of a metallic or combing
sound in the pitch shift, but can sometimes be
audible as a click or a glitch. Longer splices are
sometimes less obvious, but can affect the timbre of
the sound. High values of pitch shift require short
splices, so SPL is deactivated if the pitch shift selected
is quite high. The default value of 16 gives good results
in most applications.
Program Descriptions
1 Pitch Change
This program has pitch values set to 0 and is set for
stereo shift.
2 Pitch Chorus
Pitch Chorus is a dual mono program, which means
that both the left and right channels can be set for
different amounts of pitch shift. The left channel is
preset for -3 cents. The right channel is preset for +6
cents. This produces a medium rolling chorus effect
with a lush characteristic.
3 1% Up 1% Down
This is another dual mono program. The pitches are set
1% up and 1% down, creating a heavily processed
sound. 39.27 ms and 32.69 ms of delay are used on the
pitches, reinforcing the overall effect. This program is
ideal for guitar and vocals.
4 Barber Pole
This is a true stereo program. Both sides are set for 3
cents of downward pitch shift. No additional delay is
used, but -41% feedback is assigned to the left and
+41% is assigned to the right. This helps give the
smooth, slow downward resonance characteristic of
this program. Use the left/stereo Pitch slider for additional
amounts of stereo pitch shifting.
5 Half Steps
This stereo program uses 600 ms of delay and 44%
feedback on both left and right channels, routed back
to a Minor 2nd downward pitch shift. This program is
strictly for effects use — try changing the delay settings
for even more outrageous effects.
6 Stair Case
This is a dual mono variation of Half Steps with shorter
delays and larger intervals.
