Chapter 4 Setting Up Your System 83

Hard Drives and Storage Locations

Music production generates a huge number of large files. These include samples for

audio instruments, loop libraries, audio recordings, video files, and more.

Consider buying a separate, large capacity hard drive (or several) for your audio files

and sample libraries.

You should also look at a reliable, high-capacity backup system, and should automate

your backup routine, preferably as a daily occurrence.

Audio and MIDI Interfaces

An audio interface is required—to get sound signals into, and out of, your computer. A

MIDI interface is required for MIDI input and output signals.

When using optional audio and MIDI interfaces, you should install their drivers before

starting Logic Pro. This will allow Logic Pro to find and use these devices at startup.

Audio interfaces should be supported by a Core Audio driver and MIDI interfaces

should be supported by a Core MIDI driver. Check with the manufacturer of your

equipment for details on Mac OS X support.

Audio Interface

When an analog audio signal arrives at the inputs of your audio interface, it must be

converted into digital information before the computer can deal with it. This process is

called analog to digital conversion and is handled by the analog to digital converter of

the audio interface.

There are countless optional audio interfaces available, and at least as many ways that

they can be set up and used with Logic Pro and external audio gear. Given the differing

requirements and working methods of people across the world, there is no one size fits

all audio interface solution. In the simplest scenario, you would use the internal audio

interface of your computer to monitor and record audio.

When choosing an audio interface, ensure that it is certified to run on Macintosh

hardware. If the device requires a driver, check that it is compatible with the Mac OS X

version required by Logic Pro.

Logic Pro supports input from digital audio interfaces up to a maximum sample rate of

192 kHz, and a maximum bit depth of 24 bits.

Full details on setting up your audio interface hardware, including information on

optimizations, drivers, and more can be found in “Configuring Your Audio Hardware” on

page 96, and the topic areas that follow this section.
