Roland BK-9 - Chorus

‘Performance Edit’ parameters
133
Reverb Edit “5. Room1” ~ “12. Pan Delay” Types
Parameter Setting Explanation
Feedback 0~127 Adjusts the amount of delay feedback.
Chorus
Parameter Setting Explanation
Chorus Switch O, On
Select “O” if you don’t need any chorus
eect.
Chorus Type
1: Chorus1,
2: Chorus2,
3: Chorus3,
4: Flanger,
5: GM2Chorus,
6: Delay
This parameter allows you to select one
of the twelve eects types, one of which
is actually a delay eect.
Chorus Edit
The parameters to assign depend on
the Chorus Type that you selected. See
below.
Chorus Edit “1: Chorus1” ~ “4: Flanger” Types
Parameter Setting Explanation
Level 0~127 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 eect
you select
Filter Type OFF, LPF, HPF
This allows you to specify whether or not
the incoming signal should be ltered
before being processed by the chorus.
This may be helpful to avoid a cluttered
sound image or to preserve the “punch”
of bass signals. Select “OFF” if you
don’t need any ltering. “LPF” cuts the
frequency range above the “Cuto
Freq”. “HPF” cuts the frequency range
below the “Cuto Freq”.
Cuto Freq 200~8000Hz
Basic frequency of the lter. This has no
eect if you select “OFF” as lter 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 synchronized 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.
Rate Hz 0.05~10.00Hz
Species the modulation 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 modulated. Higher
values result in a more pronounced
modulation.
Phase 0~180 deg
Spatial spread of the sound (i.e. the
“stereoness” of the eect).
Chorus Edit “1: Chorus1” ~ “4: Flanger” Types
Parameter Setting Explanation
Feedback 0~127
This parameter sets the level at which
the chorus sound is re-input (fed back)
into the chorus. By using Feedback, a
denser Chorus sound can be created.
Higher values result in a greater
feedback level.
Chorus Edit “5: GM2Chorus” Type
Parameter Setting Explanation
Level 0~127 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 eect
you select
Pre LPF 0~7
Cuts the high frequency range of
the sound coming into the chorus.
Higher values will cut more of the high
frequencies.
Level 0~127 Output level of the chorus signal
Feedback 0~127
Adjusts the amount of the chorus sound
that is fed back into the eect.
Delay 0~127
Adjusts the delay time from the direct
sound until the chorus sound is heard.
Rate 0~127
This parameter sets the speed
(frequency) at which the chorus sound is
modulated.
Higher values result in faster modula-
tion.
Depth 0~127
This parameter sets the depth at which
the chorus sound is modulated.
Higher values result in a more
pronounced modulation.
Reverb Send 0~127
This parameter sets the amount of
chorus sound that is sent to the Reverb
processor.
The value “127” eectively allows you to
connect the chorus and reverb eects in
series (Chorus before Reverb).
If you do not want the chorus signal to
be processed by the
Reverb eect, set this value to “0”.
Chorus Edit “6: Delay” Type
Parameter Setting Explanation
Level 0~127 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 eect
you select
L Delay Sync msec, Note
Use this parameter to specify whether
(“Note”) or not (“msec”) the delay time
should be synchronized to the tempo.
Depending on your choice, the setting
range of the following parameter refers
to a time (msec) or a note value.
