0002 Threshold 7 0 - 127 0 - 127
0003 Release 7 0 - 127 0 - 127
Operation
This module is for noise cancellation when there is no signal.
The input signal is output as-is, but whenever theinput signal level drops below a certain value for
a specific time the gate closes and output is muted.
1. Bypass
Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.
2. Threshold
Noise gate operation threshold level. Output is muted when the input signal is at or below the
level specified here.
3. Release
Time the noise gate is closed when muting is performed.

4.8.6.4 System Noise Gate
Specifications
TypeID FXID_SYNOI = 0012H
I/O 2/2
Available Part System Noise Gate
Operation
The system-wide master noise gate always performs correct operation automatically, so there is
never any need to even be away of its existence.

Operation
This effector lowers the volume when the input signal is at or above a specified level. This func-
tion can be employed to achieve either of the two objectives described below.
Compressor
Volume is raised when the input signal is small and lowered when the input signal is large. This
suppresses wide variations in volume levels, which makes it possible to sustain decay type instru-
ment tones longer.
Limiter
Since the operation start level is set comparatively higher than that of the compressor, when the
input signal as at or below a certain level, it is output as-is. When the input signal is at or above a
certain level, the input the output amplification factor is reduced, which suppresses the output
signal peak.
1. Bypass
Effector function enable/disable. Selecting bypass causes the input signal to be output as-is.
2. Attack
Level of attack for the signal rise. Theoretically,it controls the time it takes from the point the
input signal rises to a preset level until the compressor/limiter effect is applied. A late attack
keeps the signal attack part from being compressed, which makes it possible to maintain the
attack only.
3. Release
Time from the point when the input signal drops below the threshold level until the compres-
sor/limiter function stops
