Signal gate algorithms
Allocation Units: 1 for Gate; 2 for Super Gate
Gate and Super Gate do stand-alone gate processing and can be configured as a stereo or mono effects. As a stereo
effect, the stereo signal gates itself based on its amplitude. As a mono effect, you can use one mono input signal to
gate a second mono input signal (or one channel can gate itself). Separate output gain and panning for both channels
is provided for improved mono processing flexibility.
Gate
A gate behaves like an on off switch for a signal. One or both input channels is used to control whether the switch
is on (gate is open) or off (gate is closed). The on/off control is called Òside chainÓ processing. You select which of
the two input channels or both is used for side chain processing. When you select both channels, the sum of the left
and right input amplitudes is used. The gate is opened when the side chain amplitude rises above a level that you
specify with the Threshold parameter.
Super Gate will behave differently depending on whether the Retrigger parameter is set to off or on.
If Retrigger is on, the gate will stay open for as long as the side chain signal is above the threshold. When the signal
drops below the threshold, the gate will remain open for the time set with the Gate Time parameter. At the end of
the Gate Time, the gate closes. When the signal rises above threshold, it opens again. What is happening is that the
gate timer is being constantly retriggered while the signal is above threshold. You will typically use the gate with
Retrigger on for percussive sounds. For the simpler Gate, there is no Retrigger parameter, and it is as if Retrigger is
always on.
