Signal envelope for Gate and Super Gate when Retrigger is ÒOnÓ
If Retrigger is off (Super Gate only), then the gate will open when the side chain signal rises above threshold as
before. The gate will then close as soon as the gate time has elapsed, whether or not the signal is still above
threshold. The gate will not open again until the envelope of the side chain signal falls below the threshold and rises
above threshold again. Since an envelope follower is used, you can control how fast the envelope follows the signal
with the Env Time parameter. Retrigger set to off is useful for gating sustained sounds or where you need precise
control of how long the gate should remain open.
Super Gate signal envelope when Retrigger is ÒOffÓ
If Ducking is turned on, then the behavior of the gate is reversed. The gate is open while the side chain signal is
below threshold, and it closes when the signal rises above threshold.
If the gate opened and closed instantaneously, you would hear a large digital click, like a big knife switch was being
thrown. Obviously thatÕs not a good idea, so Atk Time (attack) and Rel Time (release) parameters are use to set the
times for the gate to open and close. More precisely, depending on whether Ducking is off or on, Atk Time sets how
fast the gate opens or closes when the side chain signal rises above the threshold. The Rel Time sets how fast the
