Boss VF-1 - Flanger; GRAPHIC EQ (Graphic Equalizer)

98
The function of each parameter
VIB DEPTH (vibrato depth)
This adjusts the depth of the vibrato when the feedbacker is
on.
<When “BOOST” is selected>
F.B DEPTH (feedback depth)
Adjust the amount of boost for the feedback frequency.
FEEDBACK TONE
Adjust the frequency range at which you wish to create
feedback.
FLANGER
The flanger effect gives a twisting, jet-airplane-like character
to the sound.
EFFECT
This parameter turns the flanger effect on/off.
RATE
Determines the rate of the flanging effect.
* If this is set to BPM, the MASTER BPM (p.105) setting for
each patch will determine the rate, so that the effect sound will
match the song tempo. However, if the BPM value is high, the
effect will synchronize to 1/2 or 1/4 of the BPM.
DEPTH
Determines the depth of the flanging effect.
MANUAL
Adjusts the center frequency at which to apply the effect.
RESONANCE
Determines the amount of resonance (feedback). Increasing
the value will emphasize the effect, creating a more unusual
sound.
SEPARATE (separation)
Adjusts the diffusion. The diffusion increases as the value
increases.
LEVEL
This adjusts the volume of the flanger.
GATE
This can be effectively used to cyclically cut the output from
the flanger. Increasing the value will shorten the interval. If
this is “Off,” gate will have no effect.
DIRECT SWITCH
Switch the direct sound on/off (output/no output).
GRAPHIC EQ
(graphic equalizer)
This simulates a 10-band graphic equalizer.
EFFECT
This parameter turns the graphic EQ effect on/off.
INPUT GAIN
Adjust the overall volume level of the sound before it passes
through the equalizer.
LEVEL
Adjust the volume level of the sound which as passed
through the equalizer.
31.2–16KHz (Gain)
Adjust the gain (amount of boost/cut) of the equalizer for
each frequency.
FEEDBACKER ON/OFF
To switch the feedbacker on/off using the Footswitch
(FS-5U, DP-2 (Roland), etc.), set “Control Assign” (p. 33)
as follows.
< ASSIGN1: ON >
TARGET: SFX: ON/OFF
TARGET MIN: OFF
TARGET MAX: ON
SOURCE TYPE: CONTROL1
SOURCE MODE: NORMAL
SOURCE MIN: 0
SOURCE MAX: 127
