Stereo Pitch Shift Mode, Pitch and Effects Page
MODE selects stereo or mono mode. In stereo the two channels are linked, pitch
shifting by the same amount and splicing at the same time.
GLDL affects both channels in stereo mode, and the left channel in mono mode.
GLDR affects the right channel in mono mode. These controls change the pitch
continuously over a range of -2octaves to +1 octave. This allows a glissando to
be performed, either manually or via MIDI.
PCHL 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.
In the long display, the Fine Pitch is shown by the number of cents added to, or
subtracted from, the semitone intervals. Remember that Pitch Interval will
produce exact intervals only if Fine Pitch is centered. The rightmost character in
the long display is an asterisk (*) if Fine Pitch is centered, and a '+' or '-' otherwise.
When the VALUE key turns on the short value display, Fine Pitch is not shown
in cents, but as a number ranging from -32 to +32 in order to give a clear
indication of how much Pitch Interval has been changed. When '**' is shown, Fine
Pitch is centered and inactive. As a rule, 1 count of Fine Pitch is worth 2 cents
near 200%, 3 cents near 100%, 6 cents near 50%, and 12 cents near 25%.
PCHR performs the same functions as the PCHL control, except that it is only
active in Mono mode, in which it adjusts the right channel.
FINL acts on both channels together in stereo mode, and the left channel in mono
mode. It adjusts pitch continuously over a range of a few hundred cents, and is
additive to the PCHL control. If PCHL is set to the middle of its range the FINL
control can be used to set very small values of pitch shift, producing a chorusing
effect.
FINR performs the same functions as the FINL control, except that it is only
active in Mono mode, in which it adjusts the right channel.
