PART 3: The Acadia Audio System
Mono and Stereo Plug-Ins
There are basically three types of
plug-ins:
• mono in/mono out
These plug-ins can only be assigned
to a mono Audio Instrument (or
mono input, output, or bus), and their
output can only be connected to
another “mono in” plug-in.
• mono in/stereo out
These plug-ins can only be assigned
to a mono Audio Instrument (or
mono input, output, or bus), and their
output is generally connected to a
“stereo in” plug-in.
Vision can, however, use this plug-in
type as a mono in/mono out plug-in
by only outputting its left channel.
When viewing mono in/stereo out
plug-ins in the Plug-In Selector popup,
a duplicate of each plug-in
(labeled as “mono”) is displayed in
the left column of the menu.
• stereo in/stereo out
These plug-ins can only be assigned
to a stereo Audio Instrument (or
stereo input, output, or bus), and
their output can only be connected to
another “stereo in” plug-in.
Some VST plug-ins can be used in just one
mode. Still others can be used in two
modes—mono in/stereo out or stereo in/
stereo out.
Some manufactures, on the other hand,
provide two different versions of their
plug-ins for connecting to either mono or
stereo. Usually, these plug-ins are named
accordingly (for instance, “DeNoiserM”
and “DeNoiserS”).
Vision represents plug-in routings graphically
in the Console Window, as shown in
Figure 7.6.

NOTE: A mono Audio Instrument can
have stereo plug-in inputs if the plug-in
above it contains a mono in/stereo out
plug-in. For more information, see “Using
Mono Plug-Ins (pg. 51).”
