Updating Digi 002 Firmware

The Digi 002 has three types of firmware: Boot 
Firmware, System Firmware, and Fader Firm-
ware. The second and third types, System and 
Fader firmware, can be updated automatically 

When you launch Pro Tools software, it auto-
matically checks the version of the unit’s firm-
ware, and prompts you to update it if newer ver-
sions are available. 

If you choose to update your unit’s firmware, be 
sure to allow the update to complete before dis-
connecting or turning off your system.

When the download and reprogramming pro-
cess is complete, you may get a message that 
Pro Tools cannot communicate with Digi 002. 
In this case, wait up to 30 seconds; if the mes-
sage does not go away, disconnect and then re-
connect Digi 002 and click OK.

Configuring Pro Tools

Configuring the Playback Engine

The Playback Engine lets you customize various 
System Usage parameters (such as Hardware 
Buffer Size and CPU Usage) and set the size of 
the DAE Playback Buffer. 

In most cases, the default settings for your sys-
tem provide optimum performance, but you 
may want to adjust them to accommodate large 
or processing-intensive Pro Tools sessions. 

To configure Playback Engine settings:

1  

Choose Setups > Playback Engine.

2  

From the H/W Buffer Size pop-up, select the 

audio buffer size, in samples, for host processing 
tasks such as Real-Time AudioSuite (RTAS) plug-
in processing. The default setting is 512 sam-
ples. Select a higher setting if you need more 
buffer time for processing audio and applying 
real-time effects. (H/W Buffer size has an effect 
on monitoring of audio in Pro Tools; see “Mon-
itoring Latency and Recording” on page 68 for 
details.)

3  

From the CPU Usage Limit pop-up, select the 

maximum percentage of CPU resources to allo-
cate to host processing tasks. The default setting 
is 65%. Select a higher setting if you need more 
host processing power for RTAS applications.

4  

Set the DAE Playback Buffer Size. (See “DAE 

Playback Buffer Size” on page 20.) Memory re-
quirements for each setting are shown at the 
bottom of the Playback Engine dialog box.

5  

When finished, click OK.

DAE Playback Buffer Size

The DAE Playback Buffer Size determines the 
amount of memory allocated within DAE to 
manage disk buffers, which affects system per-
formance.
