RTAS Engine Options
Pro Tools provides two RTAS Engine options in
the Playback Engine dialog for suppressing RTAS
error reporting during playback and recording.
This is especially useful when working with in-
strument plug-ins.
You should only enable RTAS error suppression
if you are experiencing frequent RTAS errors
that are interrupting your creative workflow.
When RTAS error suppression is enabled, you
can experience a degradation of audio quality.
However, this may be acceptable in order to
avoid interrupting playback and recording
when working with instrument plug-ins. Be sure
to disable RTAS error suppression when you
need to ensure the highest possible audio qual-
ity, such as for a final mix.
Enabling RTAS Error Suppression
To enable RTAS error suppression:
1
Choose Setup > Playback Engine.
2

If available, you can also select Minimize Ad-
ditional I/O Latency.
