Connecting Your Audio Interface
Logic Pro supports plug and play for audio interfaces, making it possible to connect
and switch on a new audio interface while Logic Pro is running. An alert appears when
you connect a new device, and will prompt you to select and confirm the audio
interface and driver that you would like to use.
All digital audio interfaces can be susceptible to latency—a noticeable delay between
the time the audio signal is produced, and when you hear it. You should always attach
your audio interface directly to the computer, rather than through a hub, or daisy-
chaining it through another device. Doing so can cause an unacceptable amount of
latency, particularly with slower USB 1.1 devices.
MIDI Cabling
MIDI is an abbreviation for Musical Instrument Digital Interface—a universal 5-pin
connection standard and computer language—that allows communication between
MIDI devices.
Connecting Your MIDI Keyboard and Modules
If using a simple MIDI master keyboard, without internal tone generation facilities, you
only need to connect the MIDI Out port of the keyboard to a MIDI In port on your MIDI
interface—using a MIDI cable.
