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.
fig.MFX-24
This is a flanger in which the flanger pitch changes in steps. The speed
at which the pitch changes can also be specified in terms of a note-
value of a specified tempo.
fig.MFX-25
Uses a six-phase chorus (six layers of chorused sound) to give richness
and spatial spread to the sound.

24: FLANGER
Parameter Value Description
Filter Type 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
Cutoff Freq 200–8000 Hz Basic frequency of the filter
Pre Delay 0.0–100.0 ms
Adjusts the delay time from when
the direct sound begins until the
flanger sound is heard.
Rate 0.05–10.00 Hz, note Frequency of modulation
Depth 0–127 Depth of modulation
Phase 0–180 deg Spatial spread of the sound
Feedback -98– +98%
Adjusts the proportion of the
flanger sound that is fed back into
the effect. Negative (-) settings will
invert the phase.
Low Gain -15– +15 dB Gain of the low range
High Gain -15– +15 dB Gain of the high range
Balance D100:0W–D0:100W
Volume balance between the direct
sound (D) and the flanger sound (W)
Level 0–127 Output Level
25: STEP FLANGER

heard.
Rate 0.05–10.00 Hz, note Frequency of modulation
Depth 0–127 Depth of modulation
Pre Delay
Deviation
0–20
