3 To hear the audio source you have selected to
control side-chain input, click Key Listen.
4 To filter the Key Input so that only specific fre-
quencies trigger the plug-in, use the Key HPF
and Key LPF controls (if available) to select the
desired frequency range.
5 Begin playback. The plug-in uses the input or
bus that you chose as a Key Input to trigger its
effect.
6 Adjust the plug-in’s Threshold control (if
available) to fine-tune Key Input triggering.
7 Adjust other controls to achieve the desired ef-
fect.
Tempo Sync
Pro Tools 6.2 and higher provides Tempo Sync to
enhance MIDI Beat Clock support and overall
tempo capabilities of plug-ins that utilize MIDI
Beat Clock.
Tempo Sync provides a direct connection be-
tween session tempo and plug-in parameters
that support MIDI Beat Clock. This direct con-
nection lets plug-in parameters such as delay,
auto-pan, and other time-domain effects auto-
matically synchronize to and follow changes in
session tempo.
Tempo Sync simplifies MIDI Beat Clock config-
uration by making session tempo available to
relevant plug-in parameters directly from
within the plug-in window. For plug-ins that do
not support Tempo Sync, the original MIDI Beat
Clock window (MIDI > MIDI Beat Clock) re-
mains available in Pro Tools.
Compatibility and Settings
When opening older sessions that included
plug-ins that subscribe to MIDI Beat Clock
(Pro Tools 6.1.x and lower), Tempo Sync will be
automatically enabled. Any plug-ins that used
automation for tempo change should have that
automation suspended or deleted to avoid con-
flict with Tempo Sync.
Tempo Sync is not available in plug-ins
with which it would limit functionality. For
example, for the Virus Indigo and
IndigoV40 plug-in, use the Pro Tools MIDI
Beat Clock window (MIDI > MIDI Beat
Clock). See the Pro Tools Reference Guide
for more information.
