Parameters for the “5. GM2Chorus” type:
Output Select Main, Rev,
Main+Rev
Allows you to specify
where the processor’s
output signal should
go: to the OUTPUT
(“Main”), the Reverb
processor (“Rev”) or
both (“Main+Rev”). The
latter two options
mean that the chorus
signal is also pro-
cessed by the reverb
effect you select.
Filter Type OFF, LPF, HPF This allows you to
specify whether or not
the incoming signal
should be filtered
before being pro-
cessed by the chorus.
This may be helpful to
avoid a cluttered
sound image or to pre-
serve the “punch” of
bass signals. Select
“OFF” if you don’t need
any filtering. “LPF” cuts
the frequency range
above the “Cutoff
Freq”. “HPF” cuts the
frequency range below
the “Cutoff Freq”.
Cutoff Freq 200~8000Hz Basic frequency of the
filter. This has no
effect if you select
“OFF” as filter type.
Pre Delay 0.0~100.0 ms Adjusts the delay time
from the direct sound
until the chorus sound
is heard.
Rate Sync Hz, Note Use this parameter to
specify whether
(“Note”) or not (“Hz”)
the modulation rate
should be synchro-
nized to the Arranger
or Recorder tempo.
Depending on your
choice, the setting
range of the following
parameter refers to a
speed (Hz) or a note
value.
Parameter Setting Explanation
Rate Hz 0.05~10.00Hz Specifies the modula-
tion speed. This can be
either a frequency (Hz)
or a note value,
depending on how you
set the “Rate Sync”
parameter above. “T”
means “triplet” and a
“.” refers to a dotted
note. “2/1” means that
each cycle takes two
measures/bars. The
advantage of working
with a note value is
that the chorus will
undulate in sync with
the current Arranger or
Recorder tempo.
Rate Note 1/64T, 1/64, 1/
32T, 1/32, 1/
16T, 1/32., 1/
16, 1/8T, 1/16.,
1/8, 1/4T, 1/8.,
1/4, 1/2 T, 1/4.,
1/2, 1/1 T, 1/2.,
1/1, 2/1 T, 1/1.,
2/1
Depth 0~127 This parameter sets the
depth at which the
chorus sound is modu-
lated. Higher values
result in a more pro-
nounced modulation.
Phase 0~180 deg Spatial spread of the
sound (i.e. the “stereo-
ness” of the effect).
Feedback 0~127 This parameter sets the
level at which the cho-
rus sound is re-input
(fed back) into the
chorus. By using Feed-
back, a denser Chorus
sound can be created.
Higher values result in
a greater feedback
level.
Parameter Setting Explanation
Level 0~127 Main Output level of
the chorus signal.
Output Select Main, Rev,
Main+Rev
Allows you to specify
where the processor’s
output signal should
go: to the OUTPUT
(“Main”), the Reverb
processor (“Rev”) or
both (“Main+Rev”). The
latter two options
mean that the chorus
signal is also processed
by the reverb effect
you select.
