62: 2VOI PITCH SHIFTER (2VOICE PITCH SHIFTER)
Parameter Value Description
Pitch 1:
Coarse
-24-+12 semi
Adjusts the pitch of Pitch Shift 1
in semitone steps.
Pitch 1:Fine -100-+100 cent
Adjusts the pitch of Pitch Shift
Pitch 1 in 2-cent steps.
Pitch 1:Delay 0–1300 ms, note
Adjusts the delay time from the
direct sound until the Pitch Shift 1
sound is heard.
Pitch 1:Feedback -98– +98%
Adjusts the proportion of the
pitch shifted sound that is fed
back into the effect. Negative (-)
settings will invert the phase.

Proportion of the pitch-shifted sound
that is to be returned to the input
(negative values invert the phase)

64: REVERB
Parameter Value Description
Type
ROOM1, ROOM2,
STAGE1, STAGE2,
HALL1, HALL2
Type of reverb
ROOM1: dense reverb with
short decay
ROOM2: sparse reverb with
short decay
STAGE1: reverb with greater
late reverberation
STAGE2: reverb with strong
early reflections
HALL1: reverb with clear rever-
berance
HALL2: reverb with rich rever-
berance
Pre Delay 0.0–100.0 ms
Adjusts the delay time from the di-
rect sound until the reverb sound
is heard.
Time 0–127 Time length of reverberation
HF Damp
200–8000 Hz,
BYPASS
Adjusts the frequency above which
the reverberant sound will be cut.
As the frequency is set lower,
more of the high frequencies
will be cut, resulting in a softer
and more muted reverberance.
If you do not want to cut the
high frequencies, set this pa-
rameter to BYPASS.
Low Gain -15– +15 dB Gain of the low range
High Gain -15– +15 dB Gain of the high range
Balance D100:0W–D0:100W
