Chapter 33: Multichannel Tracks and Signal Routing (Pro Tools HD Only) 771
Multichannel Plug-ins Are designed for use on
stereo and multichannel tracks that require cor-
related processing, including stereo and multi-
channel limiting, compression, and similar ef-
fects.
Linking and Unlinking Controls on Multi-
Mono Plug-ins
When a multi-mono plug-in is used on a multi-
channel track of more than two channels, the
controls are normally linked. Adjusting the
Gain control on one channel, for example, will
adjust it for all channels.
If necessary, you can unlink plug-in controls on
specific channels of a track and edit them inde-
pendently. You can also selectively link the con-
trols of specific channels.
For example, to apply equal filter cutoffs to the
Ls and Rs (surround) channels in a 5.1 mix, you
could link enable just those channels in an un-
linked, multi-mono EQ plug-in. Adjusting the
controls in the plug-in window for either chan-
nel (Ls or Rs) adjusts the other, linked channel
as well.
Channel Selector
Accesses a specific channel
within a multichannel track for plug-in parame-
ter editing. This menu appears only on multi-
mono plug-ins inserted on tracks with more
than two channels.
Master Link Button When enabled, links the
controls on all channels of a multi-mono plug-
in so that they can be adjusted in tandem.
Link Enable Buttons Let you selectively link the
controls of specific channels of a multi-mono
plug-in. Each square represents a speaker chan-
nel. The Master Link button must be disabled to
use the Link Enable buttons.
