Using the TL EveryPhase Side-Chain Input
The Side-Chain Input option in TL EveryPhase lets you direct audio from another track in your Pro Tools session to the Envelope Detector. This is achieved by sending the audio from the desired channel to a bus and setting the side-chain input on TL EveryPhase to the same bus.
The Side-Chain Input feature lets you control the TL EveryPhase modulation and LFO using external audio sources, allowing you to explore creative possibilities not available with most phasers.
For example, a side-chain input can be used to “listen” to a percussion track and create a rhythmic phasing effect on a bass line. This is especially effective in R&B, hip hop and electronic music.
Consider the following two bar bass line and drum loop. The bass line is simply a single bass guitar note which lasts for almost an entire bar.
3 Set the Side-Chain Input on TL EveryPhase to listen to the selected bus.
4 Activate the Side-Chain Input in TL EveryPhase by selecting the key icon in the Envelope section.
5 The Side-Chain audio can modulate the audio directly by selecting Source:Envelope in the Modulation section. Alternatively, the Side-Chain Input can be used to trigger the LFO by selecting the Envelope trigger in the LFO section.
6 After starting the transport, adjust the Threshold in the Envelope section until the drum loop is triggering the Envelope Detector. This is shown by the Source:Envelope or Envelope trigger light blinking brighter, as well as shown by the action of the Modulation Meter.
7 The Attack and Decay in the Envelope section can also be adjusted to suit your needs.
The phased bass line is shown below after being recorded to a separate track. The effect of TL EveryPhase triggered by the drum loop can be seen in the resulting waveform.
