Noise Suppressor; Octave; Phaser; Pitch Shifter - Boss BR-864 Owner's Manual

Modify Fil
This is a filter featuring a wide range of possible settings (modifiable
filter). Select different types to get a variety of different filter effects.
OFF:
The modify filter will not be used.
LPF:
The effect will function as a low pass filter.
BPF:
The effect will function as a band pass filter.
HPF:
The effect will function as a high pass filter.
Cutoff F
Adjust the cutoff frequency.
Resonance
Adjust the resonance.
Gain
Adjust the volume level of the sound that has passed through the
modify filter.

Noise Suppressor

This effect reduces the noise and hum. Since it suppresses the noise
in synchronization with the envelope of the sound (the way in which
the sound decays over time), it has very little effect on the sound,
and does not harm the natural character of the sound.
On/Off
This parameter turns the noise suppressor effect on/off.
Threshold
Adjust this parameter as appropriate for the volume of the noise. If
the noise level is high, a higher setting is appropriate. If the noise
level is low, a lower setting is appropriate. Adjust this value until the
decay of the sound is as natural as possible.
* High settings for the Threshold parameter may result in there being no
sound when you play with your instruments volume turned down.
Release
Adjusts the time from when the noise suppressor begins to function
until volume reaches "0."

Octave

This adds a note one octave lower, creating a richer sound.
On/Off
This parameter turns the octave effect on/off.
Oct Level
This adjusts the volume of the sound one octave below.
Dir Level
Adjusts the volume of the direct sound.
Insert Effect Parameter Functions

Phaser

By adding varied-phase portions to the direct sound, the phaser
effect gives a whooshing, swirling character to the sound.
* This effect can be used when the MODULATION "Type" parameter
is set to "PHASER."
On/Off
This parameter turns the phaser effect on/off.
Rate
This sets the rate of the Phaser effect.
Depth
0–100
Determines the depth of the Phaser effect.
Manual
0–100
Adjusts the center frequency of the phaser effect.
Resonance
0–24 dB
Determines the amount of resonance (feedback). Increasing the value
will emphasize the effect, creating a more unusual sound.

Pitch Shifter

This effect changes the pitch of the original sound (up or down)
within a range of two octaves.
* This effect can be used when the MODULATION "Type" parameter
is set to "PITCH SFT."
On/Off
OFF, ON
This parameter turns the pitch shifter effect on/off.
Type
0–100
Selects either manual pitch shifter "MANUAL" or pedal pitch shifter
"PEDAL."
MANUAL:
This is a simple pitch shifter.
PEDAL:
The effect will function as a pedal pitch shifter. The effect of the wah
pedal can be obtained by operating the Expression pedal. For a
0–100
detailed explanation, see "When using an expression pedal" (p. 136).
Pitch
Adjusts the amount of pitch shift (the amount of pitch change) in
semitone steps. By selecting "DETUNE," you can add a slightly
pitch-shifted sound to the input sound, producing a detune effect.
* This effect can be used when the "P.Shift Type" parameter is set to
"MANUAL."
OFF, ON
D:E
This adjusts the volume balance of the direct and effect sounds.
0–100
Separation
Adjusts the diffusion. The panning of the direct sound and effect
0–100
sound can be spread to left and right. This will be effective when
stereo output is used.
