On an acoustic piano, holding down the damper pedal allows other
strings to resonate in sympathy with the notes you play, creating rich
and spacious resonances. This effect simulates these sympathetic
resonances.

77: CHORUS FLANGER
Parameter Value Description
Chorus Pre
Delay
0.0–100.0 ms
Adjusts the delay time from the direct
sound until the chorus sound is heard.
Chorus Rate 0.05–10.00 Hz, note
Modulation frequency of the chorus
effect
Chorus Depth 0–127
Modulation depth of the chorus effect
Chorus Balance D100:0W–D0:100W
Volume balance between the direct
sound (D) and the chorus sound (W)
Flanger Pre
Delay
0.0–100.0 ms
Adjusts the delay time from when
the direct sound begins until the
flanger sound is heard.
Flanger Rate 0.05–10.00 Hz, note
Modulation frequency of the flanger
effect
Flanger Depth 0–127
Modulation depth of the flanger effect
Flanger
Feedback
-98– +98%
Adjusts the proportion of the flanger
sound that is fed back into the ef-
fect. Negative (-) settings will invert
the phase.
Flanger Balance D100:0W–D0:100W
Adjusts the volume balance between
the sound that is sent through the
flanger (W) and the sound that is not
sent through the flanger (D).

SYMPATHETIC RESO
(SYMPATHETIC RESONANCE)
Parameter Range Explanation
Depth 0–127 Depth of the effect
Damper 0–127
Depth to which the damper pedal is
pressed (controls the resonant
sound)
Pre LPF
16–15000 Hz,
BYPASS
Frequency of the filter that cuts the
high-frequency content of the input
sound (BYPASS: no cut)
Pre HPF
BYPASS,
16–15000 Hz
Frequency of the filter that cuts the
low-frequency content of the input
sound (BYPASS: no cut)
Peaking Freq 200–8000 Hz
Frequency of the filter that boosts/
cuts a specific frequency region of
the input sound
Peaking Gain -15– +15 dB
Amount of boost/cut produced by
the filter at the specified frequency
region of the input sound
Peaking Q
0.5, 1.0, 2.0, 4.0,
8.0
Width of the frequency region
boosted/cut by the ‘Peaking Gain’
parameter (larger values make the
region narrower)
HF Damp
16–15000 Hz,
BYPASS
Frequency at which the high-fre-
quency content of the resonant
sound will be cut (BYPASS: no cut)
LF Damp
BYPASS,
16–15000 Hz
Frequency at which the low-frequen-
cy content of the resonant sound will
be cut (BYPASS: no cut)
Lid 6–1
This simulates the actual changes in
sound that occur when the lid of a
grand piano is set at different
heights.
EQ Low Freq 200, 400 Hz Frequency of the low-range EQ
EQ Low Gain -15– +15 dB Amount of low-range boost/cut
EQ Mid Freq 200–8000 Hz Frequency of the midrange EQ
EQ Mid Gain -15– +15 dB Amount of midrange boost/cut
EQ Mid Q
0.5, 1.0, 2.0, 4.0,
8.0
Width of midrange (larger values
make the region narrower)
EQ High Freq
2000, 4000, 8000
Hz
Frequency of the high-range EQ
