A "gate" is mentioned in the user manual but there isn't any description of what it is.
Page 14:
"Additional amp and control settings can be found by continuing to scroll through the CONTROLS LAYER of various amp models within the presets. These consist of “deeper” parameters such as (depending on amp) compression sag, bias and gate controls."
Yes, John, I'd take that to mean that a noise gate control is available on those virtual amps that are modeled after actual amps that have that control. That's quite a level of detail in the modeling, isn't it? And when it says "such as" sag, bias and gate, it makes me wonder if there are others not even mentioned! Certainly leaves room for others in future, downloadable models. Hmmm ...
