Effect Block
12 2x BOSS Flanger
Flanger (Stereo flanger)
This adds a particular metallic-sounding modulation to the
source sound.
Model Type
This selects the model of flanger simulated.
Value Explanation
Normal (Normal type <BOSS BF-2>)
HiBand (High-Band type <BOSS HF-2>)
Setting HiBand raise the flanging sound one
octave above that at the Normal.
Manual
Value: 0–100
Sets the center frequency for the effect. This changes
the pitch of the flanger's metallic sound.
Depth
Value: 0–100
Sets the depth of the swelling of the flanger sound.
Rate
Value: 0–100
Sets the rate of the swelling of the flanger sound. In
Tempo Sync this is disabled, and you cannot make this
setting.
Resonance
Value: 0–100
Sets the intensity of the flanger's effect. This
corresponds to the "Feedback" setting in 11 Vintage
Flanger 325 (p. 33).
• Setting the Resonance value too high may result in
extreme oscillation. Take care to prevent this sound
from damaging your ears or your playback equipment.

Tempo Sync
Value: OFF, , , , ,
x1 – x4
Set this when synchronizing the Rate setting to the song
tempo. When not synchronizing, set this "OFF." When
you select the note, the Rate setting is disabled, and the
Rate is set the note length corresponding to the song
tempo.
• If the length of the note is set longer (or shorter) than that
of the possible range of the Rate settings by the change of
song tempo, the Rate can not correspond to the note
length. If "?" appears before the note symbol you set, it is
because the upper (or lower) limit of the setting range has
been exceeded, and that the synchronization is not correct.
Furthermore, the precision of the Rate setting and song
tempo differ. If left to develop over long periods, the two
may gradually drift apart.
LFO Phase
Value: 0–180 deg
Sets the degrees of left and right phase shift in the Low
Frequency Oscillator (LFO) that produces the flanging
cycle. You can change the timing of the rise and fall of
the modulation in the left and right channels. At 0 deg. (0
degree), the effects sounds of left and right rise and fall
together. At 180 degrees, they are completely opposite.
Cross Feedback
Value: -100–100
This setting makes the flanging sound of each of right
and left channels return to the input of the opposite
channel. This gives an even stronger flanging effect. The
plus indicates the flanging sound is returned in normal
phase, and the minus that the sound is returned in phase
inverted.
• Setting the Cross Feedback value too high may result
in extreme oscillation. Take care to prevent this sound
from damaging your ears or your playback equipment.
Cross Mix
Value: -100–100
This setting makes the flanging sound from each of the
right and left channels mix it with the flanging sound of
the opposite channel.
Switching to the plus side mixes them in phase, and
switching to the minus side has them mixed in phase
inverted.
• Cross Feedback and Cross Mix are the effect that you
cannot get even with two actual flangers connected in
parallel. These parameters have been added to this
algorithm with consideration given to their use in stereo. By
setting a negative value for the Cross Mix, you can get
stereo flanging effect that features a particular floating
sensation.
