Configuring Pro Tools
Pro Tools System Settings
Pro Tools allows you to adjust the performance
of your system by changing system settings that
affect its capacity for processing, playback, and
recording.
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.
Voice Count
The Number of Voices setting lets you control
the number of voices available on your system.
The default number on a Pro Tools|24 MIX sys-
tem is 32 voices (at sample rates of 44.1 kHz or
48 kHz).
Depending on the current sample rate and the
number of MIX Core and Farm cards in your sys-
tem, you will have different choices available for
this setting. For voice limits on different MIX
systems, refer to the Pro Tools Reference Guide.
To change the Voice Count:
1 Choose Setups > Playback Engine.
2 Select the number of voices and DSPs to allo-
cate for voicing by choosing a value from the
Number of Voices pop-up menu.
• Select higher voice numbers when your
Digidesign cards are the only PCI cards in
your computer, or when using an expan-
sion chassis to run higher track counts
(such as 64 tracks at 48 kHz).
• Select lower voice numbers if you are using
high-bandwidth PCI cards (such as video
capture cards) along with your Digidesign
cards.
3 Click OK.
Changing the number of voices affects
DSP usage, the total number of voiceable
tracks, and overall system performance.
