Chapter 60: TL EveryPhase 301
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 rhyth-
mic phasing effect on a bass line. This is espe-
cially 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.
The bass line can be phased by the drum loop as
follows:
1 Instantiate TL EveryPhase on the bass line
track.
2 Send the drum loop track to a bus.
3 Set the Side-Chain Input on TL EveryPhase to
listen to the selected bus.
4 Activate the Side-Chain Input in TL Every-
Phase 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 se-
lecting the Envelope trigger in the LFO section.
6 After starting the transport, adjust the Thresh-
old in the Envelope section until the drum loop
is triggering the Envelope Detector. This is
shown by the Source:Envelope or Envelope trig-
ger 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 Ev-
eryPhase triggered by the drum loop can be seen
in the resulting waveform.

On versions of Pro Tools prior to 7.0, RTAS
plug-ins do not provide side-chain process-
ing when used on TDM systems. Use the
TDM version of TL EveryPhase if you re-
quire side-chain processing on a TDM sys-
tem.
For more information on using the Side-
Chain Input, see the Pro Tools Reference
Guide.
