Chapter 4 Introduction to Effects and Parameters
Chapter

MASTER
The following parameters can be set with MASTER.
• NS (Noise Suppressor)
• Patch Level
• Master BPM
• FV (Foot Volume)
NS (Noise Suppressor)
This effect reduces the noise and hum picked up by guitar
pickups. Since it suppresses the noise in synchronization with
the envelope of the guitar sound (the way in which the guitar
sound decays over time), it has very little effect on the guitar
sound, and does not harm the natural character of the sound.
* Please connect the noise suppressor in the signal path prior to
the reverberation type effect. This setup will prevent an
natural break of the reverberation type effect.
Patch Level
Master BPM
FV (Foot Volume)
This is a volume control effect. Usually, this is controlled to
the EXP pedal.
You may be unable to achieve the proper Foot Volume
effect with certain Effect Chain (p. 20) settings.
(Example)
FB (OSC Mode: p. 40) or SYN (p. 47) connected at a later
point in the chain than FV
Parameter/
Range
Explanation
Effect
Off, On
Switches the noise suppressor effect on/off.
This parameter can be set with the PATCH/VALUE dial.
When NS is On, the [MASTER] indicator lights.
* Even if [MASTER] is pressed, you cannot switch the noise suppressor
on and off.
Threshold
0–100
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 guitar sound is as natural as possible.
* High settings for the threshold parameter may result in there being no
sound when you play with your guitar volume turned down.
Release
0–100
Adjusts the time from when the noise sup-
pressor begins to function until the noise
level reaches “0.”
Detect
Input, NS Input,
FV Out
This controls the noise suppressor based on
the volume level for the point specified in
Detect.
Input
Input volume from input jack.
NS Input
Noise suppressor input volume.
FV Out
Volume after passing through Foot Volume.
Parameter/
Range
Explanation
Patch Level
0–200
Adjusts the volume of the patch.
Parameter/
Range
Explanation
Master BPM
40–250
Adjust the BPM value for each patch.
* BPM (beats per minute) indicates the number of quarter note beats that
occur each minute.
* When you have an external MIDI device connected, the Master BPM
synchronizes to the external MIDI device’s tempo, making it impossible
to set the Master BPM. To enable setting of the Master BPM, set
“MIDI Sync Clock” (p. 80) to Internal.
Parameter/
Range
Explanation
Level
0–100
Adjusts the volume.

Selects how the actual volume changes in re-
sponse to the level controlled with Volume.
