General Information
When more than one insert is used on a track,
they are processed in series. Each effect is added
to that of any previous plug-ins or inserts (flow-
ing from top to bottom in the Mix window In-
serts View, and left to right in the Edit window
Inserts View).
Inserts on audio tracks and Auxiliary Inputs and
Instrument tracks are pre-fader. You can cause
clipping if you boost their gain to extremes, es-
pecially on tracks recorded at high amplitude.
Watch on-screen metering for indication of clip-
ping. (Inserts on Master Faders are post-fader.)
Using Inserts for Effects Processing
Inserts can be used in two ways:
On Single Tracks An insert can be applied to an
individual audio, Auxiliary Input, Master Fader,
or Instrument track.
With in-line inserts, you control the amount of
effect by adjusting the balance (or the wet/dry
mix) controls of the plug-in or external device.
As Shared Resources An insert can be used as a
shared resource in a send-and-return arrange-
ment, by bussing signals from several tracks to
an Auxiliary Input, and then applying the insert
to the Auxiliary Input track. You can then con-
trol the send level for each track, and the overall
level of the effect can be controlled from the
Auxiliary Input track. Using sends and other sig-
nal routing features helps maximize your sys-
tem’s processing power.
Insert Formats
Mono Inserts Used on mono tracks. Inserts that
occur on a track after a stereo insert are automat-
ically used in stereo as well.
Stereo Inserts Used on stereo tracks. A stereo
hardware I/O insert sends the signal to an in-
put/output path.
Mono In/Stereo Out Plug-in Inserts Used to re-
turn a stereo effect from a mono source. Certain
plug-ins (such as D-Verb) let you generate stereo
output from a mono channel. A track made into
stereo in this way has panning controls for each
channel of the stereo signal. Any inserts that oc-
cur on a track after a stereo insert are automati-
cally used in stereo as well.
Multi-Mono Plug-in Inserts Used on stereo or
greater-than-stereo multichannel tracks when a
multichannel version of the plug-in is not avail-
able. Controls for all channels are linked by de-
fault so that you can adjust them in tandem.
You can unlink controls for independent adjust-
ment using the Master Link button. See “Link-
ing and Unlinking Controls on Multi-Mono
Plug-ins” on page 681.
Multichannel Plug-in Inserts Used on stereo and
greater-than-stereo multichannel tracks. On
greater-than-stereo multichannel tracks, the
controls for all channels are generally linked to-
gether.
For examples of send and return busses and
other submixing setups, see “Signal Routing
for Monitoring and Submixing” on
page 650.
Relinking may cause automation to be lost.

Multi-Mono Plug-ins” on page 681
