MIDI Implementation
012a: Infinite Phaser
A phaser that continues raising/lowering the frequency at which the sound is modulated.
0123: Stereo Flanger
This is a stereo flanger. (The LFO has the same phase for left and right.) It produces a
metallic resonance that rises and falls like a jet airplane taking off or landing. A filter is
provided so that you can adjust the timbre of the flanged sound.
0127: 3D Flanger
This applies a 3D effect to the flanger sound. The flanger sound will be positioned 90
degrees left and 90 degrees right.
0128: 2Band Flanger
A flanger that lets you apply an effect independently to the low-frequency and high-
frequency ranges.
No Parameter Value Description
1 Mode 0 - 3 1, 2, 3, 4 Higher values will produce a deeper
phaser effect.
2 Speed #1 0 - 127 -100- +100 Speed at which to raise or lower the
frequency at which the sound is
modulated
(+: upward / -: downward)
3 Resonance #2 0 - 127 0-127 Amount of feedback
4 Mix 0 - 127 0-127 Volume of the phase-shifted sound
5 Pan 0 - 127 L64-63R Panning of the output sound
6 Low Gain 0 - 30 -15- +15 dB Amount of boost/cut for the low-
frequency range
7 High Gain 0 - 30 -15- +15 dB Amount of boost/cut for the high-
frequency range
8 Level 0 - 127 0-127 Output volume
No Parameter Value Description
1 Filter Type 0 - 2 Off, Lpf, Hpf Type of filter
Off: No filter is used
Lpf: Cuts the frequency range above
the Cutoff Freq
Hpf: Cuts the frequency range below
the Cutoff Freq
2 Cutoff Freq 0 - 16 200-8000 Hz Basic frequency of the filter
3 Pre Delay 0 - 125 0.0-100.0 ms Adjusts the delay time from when
the direct sound begins until the
flanger sound is heard.
4 Rate Mode 0 - 1 Hz, note When this is set to “note,” the effect is
synchronized with the tempo.
5 Rate #1 1 - 127 0.05-10.00 Hz Frequency of modulation (Hz)
6 Rate 0 - 21 note Frequency of modulation (note)
7 Depth #2 0 - 127 0-127 Depth of modulation
8 Phase 0 - 90 0-180 deg Spatial spread of the sound
9 Feedback 0 - 98 -98- +98 % Adjusts the proportion of the flanger
sound that is fed back into the effect.
Negative (-) settings will invert the
phase.
10 Low Gain 0 - 30 -15- +15 dB Gain of the low range
11 High Gain 0 - 30 -15- +15 dB Gain of the high range
12 Balance 0 - 100 D100:0W-
D0:100W
Volume balance between the direct
sound (D) and the flanger sound (W)
13 Level 0 - 127 0-127 Output Level
No Parameter Value Description
1 Filter Type 0 - 2 Off, Lpf, Hpf Type of filter
Off: No filter is used
Lpf: Cuts the frequency range above
the Cutoff Freq
Hpf: Cuts the frequency range below
the Cutoff Freq
2 Cutoff Freq 0 - 16 200-8000 Hz Basic frequency of the filter
3 Pre Delay 0 - 125 0.0-100.0 ms Adjusts the delay time from when
the direct sound begins until the
flanger sound is heard.
4 Rate Mode 0 - 1 Hz, note When this is set to “note,” the effect is
synchronized with the tempo.
5 Rate #1 1 - 127 0.05-10.00 Hz Frequency of modulation (Hz)
6 Rate 0 - 21 note Frequency of modulation (note)
7 Depth #2 0 - 127 0-127 Depth of modulation
8 Phase 0 - 90 0-180 deg Spatial spread of the sound
9 Feedback 0 - 98 -98- +98 % Adjusts the proportion of the flanger
sound that is fed back into the effect.
Negative (-) settings will invert the
phase.
10 Output Mode 0 - 1 Speaker,
Phones
Adjusts the method that will be used
to hear the sound that is output to the
OUTPUT jacks. The optimal 3D effect
will be achieved if you select
Speaker when using speakers, or
Phones when using headphones.
11 Low Gain 0 - 30 -15- +15 dB Gain of the low range
12 High Gain 0 - 30 -15- +15 dB Gain of the high range
13 Balance 0 - 100 D100:0W-
D0:100W
Volume balance between the direct
sound (D) and the flanger sound (W)
14 Level 0 - 127 0-127 Output Level
No Parameter Value Description
1 Split Freq 0 - 16 200-8000 Hz Frequency at which the low and high
ranges will be divided
2 Low Pre Delay 0 - 125 0.0-100.0 ms Delay time from when the original
sound is heard to when the low-
range flanger sound is heard
3 Low Rate Mode 0 - 1 Hz, note When this is set to “note,” the effect is
synchronized with the tempo.
4 Low Rate #1 1 - 127 0.05-10.00 Hz Rate at which the low-range flanger
sound is modulated (Hz)
5 Low Rate 0 - 21 note Rate at which the low-range flanger
sound is modulated (note)
6 Low Depth 0 - 127 0-127 Modulation depth for the low-range
flanger sound
7 Low Phase 0 - 90 0-180 deg Spaciousness of the low-range
flanger sound
8 Low Feedback 0 - 98 -98- +98 % Proportion of the low-range flanger
sound that is to be returned to the
input (negative values invert the
phase)
9 High Pre Delay 0 - 125 0.0-100.0 ms Delay time from when the original
sound is heard to when the high-
range flanger sound is heard
