Apple Logic Pro 9 - Manual (Page 45)

All information about the DAE and Direct TDM panes can be found in the Logic Pro TDM
Guide.
Setting Up Core Audio Devices
Logic Pro automatically recognizes any installed Core Audio hardware, and uses the
default settings as defined in the Audio MIDI Setup utility (Applications/Utilities/Audio
MIDI Setup). It can, however, be advantageous to optimize the settings for your individual
hardware setup, particularly if you use several audio interfaces or a multiple input/output
device. If possible, you should avoid using different audio devices for input and output.
For details about setting up your Core Audio device preferences (in the Logic Pro >
Preferences > Audio > Core Audio pane), see
Core Audio Device Preferences .
DAE and TDM
All information on using the DAE (Digidesign Audio Engine) and TDM hardware with
Logic Pro can be found in the Logic Pro TDM Guide.
Using Distributed Audio Processing
Distributed audio processing allows you to expand the processing capacity of your
Logic Pro system. It does this by offloading calculations for software instruments or effects
to additional Mac Node computers, connected via Gigabit Ethernet. This is perfect when
using numerous instances of processor-intensive software synthesizers or effects, such
as Sculpture or Space Designer.
Additional Mac computers do not require further copies of Logic Pro, nor any MIDI or
audio hardware.
You can find the Logic Pro Node Installer on the Logic Pro Installation DVD. Install it, and
set the system volume of your Node machine as the destination. The Logic Pro Node
application has no parameters or GUI elements. It simply needs to be open on the Node
machine before you start Logic Pro.
Tip: If you plan to use a Mac solely as a Node machine, you may want to place the
Logic Pro Node application in the Startup Items folder. You may also consider using
Apple Remote Desktop to control additional Mac computers from your primary system.
In this scenario, your Node machines don’t need their own monitors or keyboards.
Considerations for Distributed Audio Processing
Distributed audio processing actually uses the built-in networking capabilities of Mac OS X.
You will need to set up an Ethernet network connection between all computers, via the
Network pane of the System Preferences. See Mac Help for details on setting up a network.
