RTAS Engine (RTAS Error Suppression)
The RTAS Engine option determines RTAS error reporting during playback and recording. This
is especially useful when working with instrument 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 dis-
able RTAS error suppression when you need to ensure the highest possible audio quality, such
as for a final mix.
To enable RTAS error suppression:
1 Choose Setup > Playback Engine.
2 Select Ignore Errors During Playback/Record.
3 If available, you can also select Minimize Additional I/O Latency.
4 Click OK.
RTAS Error Suppression Options
There are two RTAS Engine options:
Ignore Errors During Playback/Record When enabled, Pro Tools continues to play and record
even if the RTAS processing requirements exceed the selected CPU Usage Limit. This can result
in pops and clicks in the audio, but does not stop the transport.
Minimize Additional I/O Latency (Mac Only) When enabled, any additional latency due to sup-
pressing RTAS errors during playback and record is minimized to 128 samples. Suppressing
RTAS errors requires at least 128 samples of additional buffering on some systems. If this op-
tion is disabled, the buffer is half the H/W Buffer Size, or at least 128 samples (whichever is
greater). If you are on an older, slower computer, you may want to disable this option to avoid
adverse performance.
This option is only available if the Ignore Errors During Playback/Record option is enabled.
