Modulation
Chorus (PRESET bank)
This effect creates the impression that a single sound is being played by
multiple sources. It makes the original sound richer by adding three
delays whose volume and pitch are varying cyclically. This effect uses
amplitude modulation (AM) and pitch modulation (PM).
Each aspect of the sound is controlled by the following effect parameters.
Modulation signal: FREQ., AM DEPTH, PM DEPTH, WAVE
Effect sound: MOD.DLY
Tempo synchronization: SYNC, NOTE, TEMPO
Filter/equalizer: LSH G, LSH F, EQ G, EQ F, EQ Q, HSH G, HSH F
Output level: OUT LVL, MIX BAL.

Effect list
The following table shows the default parameter values for the effects belonging to the Chorus type (PRESET bank).
■Basic parameters
Parameter name Range Explanation
FREQ. 0.05—40.00 Hz
Speed of modulation (AM, PM). Increasing this value will make the modulation repeat at a shorter
interval.
AM DEPTH 0—100%
Amplitude modulation (AM) depth. Increasing this value will produce greater volume change.
PM DEPTH 0—100%
Pitch modulation (PM) depth. Increasing this value will produce greater pitch change.
MOD.DLY 0.0—500.0 ms
Delay of the effect sound relative to the original sound.
WAVE Sine, Tri
Waveform of the modulation signal. This will affect the character of the modulation.
You can choose Sine (sine wave) or Tri (triangle wave).
Parameter name Range Explanation
MIX BAL. 0—100%
Balance between the original sound and effect sound. At a setting of 0% only the original sound
will be output; at a setting of 100% only the effect sound will be output.
OUT LVL 0—100%
Output level after the original sound and effect sound have been mixed.
Decrease this value if you want to lower the output. At a setting of 0% there will be no output.
LSH G –12.0—+12.0 dB
Gain of the low shelving filter. This adjusts the volume of the low-frequency region. Positive (+)
settings will boost the low-frequency region, and negative (–) settings will attenuate it.
LSH F 21.2 Hz—8.00 kHz
Frequency of the low shelving filter. The LSH G gain applies to the frequency region below this set-
ting.
EQ G –12.0—+12.0 dB
Gain of the equalizer (peaking type). This adjusts the gain of the frequency region specified by EQ
F. Positive (+) settings will boost the region, and negative (–) settings will attenuate it.
EQ F 100 Hz—8.00 kHz
Frequency of the equalizer (peaking type). The EQ G gain setting will affect the region around this
frequency.
EQ Q 10.0—0.10
Q (sharpness) of the equalizer (peaking type). This indicates the sharpness of the equalizer fre-
quency response curve. Higher values will produce a sharper curve.
HSH G –12.0—+12.0 dB
Gain of the high shelving filter. This adjusts the volume of the high-frequency region. Positive (+)
settings will boost the high-frequency region, and negative (–) settings will attenuate it.
HSH F 50.0 Hz—16.0 kHz
Frequency of the high shelving filter. The HSH G gain applies to the frequency region above this
setting.
SYNC ON, OFF
Switches tempo synchronization on/off. If this is ON, the speed of modulation will synchronize to
the tempo synchronization source specified by “TEMPO SOURCE” (page 23). The NOTE value
will be set to the synchronized tempo value.
NOTE
*a
*a.
This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set
according to this value and the TEMPO value. This value is ignored if SYNC is OFF.
TEMPO 25—300
This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set
according to this value and NOTE. This value is ignored if SYNC is OFF.
