Figure 7.1. Pitch Change Parameters.
The Pitch Change Programs
The Pitch Change program located in Bank 8 is a
stereo or two-channel mono pitch shifter with several
useful effects, including predelay, feedback, and glide.
These are independently adjustable for each channel.
About the Pitch Change Parameters
Page One
MOD (Stereo/Mono Mode)
MOD selects stereo or mono mode. Move the slider all
the way up to select mono, and down to select stereo.
In stereo the two channels are linked, pitch shifting by
the same amount and splicing at the same time.
SNC (Play Sync)
Normally the channels are in sync, but if PCH, FIN, or
GL are moved frequently they can get out of sync. They
can be resynchronized by pressing SNC. A small click
may be heard when the button is pressed.
PCH (Pitch Interval Stereo/Left)
PCH adjusts the pitch interval of both channels in
stereo mode, and the left channel in mono mode. The
exact tuning can be altered by the fine pitch control, and
the exact pitch shift in intervals and cents is displayed.
The fine control must be set to the exact middle of its
range if perfect pitch intervals are to be obtained.

PCH (Pitch Interval R)
This control performs the same functions as the other
PCH control, except that it is only active in Mono mode,
in which it adjusts the right channel.
FIN (Fine Pitch R)
This control performs the same functions as the other
FIN control, except that it is only active in Mono mode,
in which it adjusts the right channel.

PDL (Predelay L)
PDL adjusts the length of a delay line in series with the
left input. The range is zero to over 800 ms, with a fine
scale available when the button is pushed. Pre-delay
also affects the delay of any feedback which is applied.
In stereo mode the two predelays must be set to the
same value, or the signals will not be in phase.
PDR (Predelay R)
PDR is the same as the PDL, except that it acts upon
the right channel.
FBL and FBR (Feedback Left and Right)
FBL and FBR control the amount of feedback from the
output of the pitch shift to the input of the predelay line.
The control is at zero feedback when centered, and is
adjustable from 0 to +99%. Some very useful effects
can be obtained by combining pitch shift, delay, and
feedback.
