SPX2000—Owner’s Manual 59
Modulation
Dynamic Flanger (PRESET bank)
This effect uses the input signal or MIDI messages to vary the delay time of the effect sound, creating modulation in a specific
frequency region.
Each aspect of the sound is controlled by the following effect parameters.
Modulation signal: SOURCE
Effect sound: SENSE, OFFSET, FB.GAIN
Filter/equalizer: LSH G, LSH F, EQ G, EQ F, EQ Q, HSH G, HSH F
Output level: OUT LVL, MIX BAL.

Parameter name Range Explanation
SOURCE INPUT, MIDI
Source of the modulating signal. If you select INPUT, the effect sound will change according to the input
signal. If you select MIDI, the modulated sound will change according to the received MIDI messages
(velocity). If you want the effect to vary according to your keyboard performance, select MIDI.
SENSE 0—100
The sensitivity to SOURCE. Higher settings of this value will cause the delay time to follow the
SOURCE more faithfully. With lower settings, the delay time will follow more loosely.
OFFSET 0—100
Offset value of the delay time. This affects the delay time when a control signal is not being received.
FB.GAIN –99%—+99%
Amount of feedback for the modulated sound. Raising this value will increase the amount of feed-
back, emphasizing the modulation. Negative (–) settings will invert the phase of the feedback.
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.
DIR. UP, DOWN
Direction in which the delay time will move in response to the SOURCE signal.
DECAY
*a
*a. The range of this parameter depends on the sampling frequency at which the SPX2000 is operating.
44.1 kHz: 6 ms—46.0 s
48 kHz: 5 ms—42.3 s
88.2 kHz: 3 ms—23.0 s
96 kHz: 3 ms—21.1 s
Decay time of the flanger. This indicates the time from when the SOURCE signal is received and the delay
time changes until it returns to its original position. Higher settings of this parameter will make the delay
time return more slowly.
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.
