Configuring Pro Tools System
Settings
Pro Tools lets you adjust the performance of
your system by changing system settings that
affect its capacity for processing, playback, and
recording. These system settings are available in
the Playback Engine (Setup > Playback
Engine).
In most cases, the default settings for your sys-
tem provide optimum performance, but you
may want to adjust them to accommodate large
or processing-intensive Pro Tools sessions.
