Setting Up Core Audio Devices<br />

<strong>Logic</strong> <strong>Pro</strong> automatically recognizes any installed Core Audio hardware, and uses the<br />

default settings as defined in the Audio MIDI Setup utility (Applications/Utilities/Audio<br />

MIDI Setup). It can, however, be advantageous to optimize the settings for your individual<br />

hardware setup, particularly if you use several audio interfaces or a multiple input/output<br />

device. If possible, you should avoid using different audio devices for input and output.<br />

For details about setting up your Core Audio device preferences (in the <strong>Logic</strong> <strong>Pro</strong> ><br />

Preferences > Audio > Core Audio pane), see Core Audio Device Preferences.<br />

DAE and TDM<br />

All information on using the DAE (Digidesign Audio Engine) and TDM hardware with<br />

<strong>Logic</strong> <strong>Pro</strong> can be found in the <strong>Logic</strong> <strong>Pro</strong> TDM Guide.<br />

Using Distributed Audio <strong>Pro</strong>cessing<br />

Distributed audio processing allows you to expand the processing capacity of your<br />

<strong>Logic</strong> <strong>Pro</strong> system. It does this by offloading calculations for software instruments or effects<br />

to additional Mac Node computers, connected via Gigabit Ethernet. This is perfect when<br />

using numerous instances of processor-intensive software synthesizers or effects, such<br />

as Sculpture or Space Designer.<br />

Additional Mac computers do not require further copies of <strong>Logic</strong> <strong>Pro</strong>, nor any MIDI or<br />

audio hardware.<br />

You can find the <strong>Logic</strong> <strong>Pro</strong> Node Installer on the <strong>Logic</strong> <strong>Pro</strong> Installation DVD. Install it, and<br />

set the system volume of your Node machine as the destination. The <strong>Logic</strong> <strong>Pro</strong> Node<br />

application has no parameters or GUI elements. It simply needs to be open on the Node<br />

machine before you start <strong>Logic</strong> <strong>Pro</strong>.<br />

Tip: If you plan to use a Mac solely as a Node machine, you may want to place the<br />

<strong>Logic</strong> <strong>Pro</strong> Node application in the Startup Items folder. You may also consider using<br />

<strong>Apple</strong> Remote Desktop to control additional Mac computers from your primary system.<br />

In this scenario, your Node machines don’t need their own monitors or keyboards.<br />

Considerations for Distributed Audio <strong>Pro</strong>cessing<br />

Distributed audio processing actually uses the built-in networking capabilities of Mac OS X.<br />

You will need to set up an Ethernet network connection between all computers, via the<br />

Network pane of the System Preferences. See Mac <strong>Help</strong> for details on setting up a network.<br />
