RTAS Error Suppression

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 the final mix or audio layback.

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 Ad-

ditional I/O Latency.

4 Click OK.

RTAS Error Suppression Options

Ignore Errors During Playback/Record When en-

abled, Pro Tools continues to play and record

even if the RTAS processing requirements ex-

ceed the selected CPU Usage Limit. This can re-

sult in pops and clicks in the audio during play-

back and recording, but does not stop the

transport.

Minimize Additional I/O Latency When enabled,

any additional latency due to suppressing RTAS

errors during playback and record is minimized

to 128 samples. Suppressing RTAS errors re-

quires at least 128 samples of additional buffer-

ing on some systems. If the Minimize Addi-

tional I/O Latency option is disabled, the buffer

is half the H/W Buffer Size, or at least 128 sam-

ples (which ever is greater). If you are on an

older, slower computer, you may not want to

enable this option since doing so can adversely

affect performance.

Enabling Ignore Errors During Play-

back/Record only suppresses error reporting.

RTAS errors can result in pops and clicks in

the audio during playback and recording. To

avoid this, try increasing the CPU Usage

Limit and the HW Buffer Size, and reduce

the number of RTAS plug-ins in use in the

session.
