Modulation Plug-Ins : TL EveryPhase : TL EveryPhase Controls : Envelope Section

Envelope Section
 
When you select Envelope as the Modulation source, Modulation (as shown in the Modulation Meter) is controlled by the audio signal and the Envelope Detector section controls.
*
When the Envelope Detector is not in use, the controls in this section have no effect on the sound.
Side-Chain Input
 
When the Side-Chain Input selector (the key icon) is enabled, the audio for the Envelope Detector is taken from the side-chain input rather than the current track. Select the Side-Chain Input using the Pro Tools key icon at the top of the plug-in window.
Threshold
The Threshold slider sets the amplitude level required for the Envelope Detector. The LFO Envelope Detector light blinks brighter when audio is detected above the threshold.
Attack
The Attack slider sets the attack rate of the Envelope Detector.
Release
The Release slider sets the release rate of the Envelope Detector.
