I've never understood what "Gate" does. The "decay" and "gate" knob on any FX, I don't know what they do...? :/
They are explained in git-book.
In essence there are two equally strong reasons for using these:
*Reduction of CPU time for processing an effect.
*Avoidance of artefacts in effect processing.
I doubt it is common to actually use decay as it is supposed to be used.
Every effect that is being used, should be 'accessed' for its span, and then the decay-dial ought to have the same span in ms! That way the CPU wont be
used after the effect has ceased to be invoked.
The result is saved resources.
Today we have so immense CPU power, that we do not need to use it conservatively, but we ought to!
Gate is also an attempt to reduce CPU-usage, but more in the context of how much output of sound we would allow to occupy CPU-processing : |
A more practical POW would be that Gate settings can reduce clips in the effect attack or release
In gitBook audible output is refereed to as 'noise'

A practical example:
Add Plate-reverb to a default 3Oc
Cranck all controls to max
Now set the Gate to 0.07
The Decay to 0
play note
as you release the note there is a snuf in output, and you get an artefact clip
set decay to 2600
press note
Now you get the full effect over max time, but CPU is only used for 2600 ms
Try 2500
That is the sweetspot limit! 2550 would properly be best setting, bit that grained control is not available
