NOISE GATE eliminates noise below a certain threshold.
It is most useful when not playing, completely eliminating
noise, hum, and crackles. It does not affect the overall color
of the tone.
Parameter 1 sets the signal strength (threshold) required to
enable or disable the noise gate range from 0 (opens easily)
to 100 (opens with a stronger input signal).

COMPRESSOR produces sustain or simple “smoothing” by com-
pressing the signal so that the high levels are suppressed while
raising low level signals.
The use of compression can enhance tone and articulation.
Parameter 1 is used to set the compressor threshold level. When
the input signal exceeds this level, compression will be applied.
Parameter 2 determines the volume level.
