16 Mbox 2 Academic Getting Started Guide
To change the CPU Usage Limit:
1
Choose Setup > Playback Engine.
2
From the CPU Usage Limit pop-up menu, se-
lect the percentage of CPU processing you want
to allocate to Pro Tools.
3
Click OK.
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 disable RTAS error suppression when you
need to ensure the highest possible audio qual-
ity, such as for a final mix.
There is one RTAS Engine option:
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, but does not
stop the transport.
To enable RTAS error suppression:
1
Choose Setup > Playback Engine.
2
Select Ignore Errors During Playback/Record.
3
Click OK.
DAE Playback Buffer Size
The DAE Playback Buffer Size determines the
amount of memory DAE allocates for disk buff-
ers. The optimum DAE Playback Buffer Size for
most disk operations is Level 2.
◆
DAE Playback Buffer Size settings lower than
Level 2 may improve playback and recording
initiation speed, but may make it difficult to
play or record tracks reliably with sessions con-
taining a large number of tracks or a high den-
sity of edits, or with systems that have slower or
heavily fragmented hard drives.
◆
DAE Playback Buffer Size settings higher than
Level 2 will allow for a higher density of edits in
a session or a higher track count when using
slower hard drives. However, a higher setting
can also cause a time lag to occur when starting
playback or recording, or longer audible time lag
while editing during playback.
Using a larger DAE Playback Buffer Size
leaves less system memory for other tasks.
The default setting of Level 2 is recom-
mended unless you are encountering -9073
(“Disk too slow or fragmented”) errors.
To change the DAE Playback Buffer Size:
1
Choose Setup > Playback Engine.
2
From the DAE Playback Buffer pop-up menu,
select a buffer size.
3
Click OK.
