Figure 10-115 Signal envelope for Gate and Super Gate when Retrigger is “On”
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.
