There is one RTAS Engine option:
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.
To enable RTAS error suppression:
Choose Setup > Playback Engine.
1
Select Ignore Errors During Playback/Record.

Click OK.

DAE Playback Buffer Size
The DAE Playback Buffer Size determines the amount of
memory DAE allocates for disk buffers. The buffer size is
shown in milliseconds, which indicates the amount of
audio buffered when the system reads from disk.
24 Mbox 2 Micro Getting Started Guide
The optimum DAE Playback Buffer Size for most disk
operations is 1500 msec (Level 2).
DAE Playback Buffer Size settings lower than
1500 msec (Level 2) may improve playback and record-
ing initiation speed. However, a lower setting may make
it difficult to play or record tracks reliably with sessions
containing a large number of tracks or a high density of
edits, or with systems that have slower or heavily frag-
mented hard drives.
DAE Playback Buffer Size settings higher than
1500 msec (Level 2) allow higher track count, higher
density of edits in a session, or the use of slower hard
drives. However, a higher setting may increase the time
lag when starting playback or recording, or cause a
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 1500 msec (Level 2) is recommended
unless you are encountering -9073 ("Disk too
slow or fragmented") errors.
To change the DAE Playback Buffer Size:
Choose Setup > Playback Engine.
1
From the DAE Playback Buffer pop-up menu, select a
2
buffer size. Memory requirements for each setting are
shown at the bottom of the Playback Engine dialog.
Click OK.

If Pro Tools needs more system memory for the DAE
Playback Buffer, it will prompt you to restart your com-
puter.
