SPX2000—Owner’s Manual
Dynamic Phaser (PRESET bank)
This effect uses the input signal or MIDI messages to vary the phase-shifted frequency, creating modulation in a specific fre-
quency region.
Each aspect of the sound is controlled by the following effect parameters.
Modulation signal:
SOURCE
Phase shift:
SENSE, OFFSET, FB.GAIN, STAGE, DIR., DECAY
Filter/equalizer:
LSH G, LSH F, HSH G, HSH F
Output level:
OUT LVL, MIX BAL.

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 mes-
sages (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 phase shift frequency to follow
the SOURCE more faithfully. With lower settings, the phase shift frequency will follow more loosely.
OFFSET
0—100
Offset value of the phase shift frequency. This affects the basic frequency when a control signal is
not being received.
FB.GAIN
–99%—+99%
Amount of feedback for the effect sound. Raising this value will increase the amount of feedback,
emphasizing the modulation. Negative (–) settings will invert the phase of the feedback.
STAGE
2, 4, 6, 8, 10, 12, 14, 16
Number of stages in the phase shift circuitry. Raising this value will produce a more complex sense
of modulation.

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 phase-shifted frequency 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 phaser. This indicates the time from when the SOURCE signal is received and the
phaser moves until it returns to its original position. Higher settings of this parameter will make
the phase shift frequency 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.
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.
