Adding a Real Instrument Track

To record a Real Instrument (such as a guitar or vocal), you can add a new Real Instrument track

or record on an existing Real Instrument track. To connect an electric guitar or a professional

microphone, you’ll need additional hardware. Apple sells the $19 Monster Instrument Adaptor,

which converts a guitar’s 1/4 inch jack plug to a standard 1/8 inch minijack plug that you

connect to your Mac’s analog audio-in port; however, you can pick up a similar adaptor at your

local Radio Shack for less than $5. Although this is all you need to get your guitar sound into a

Mac, for optimal sound levels and quality, you may want to invest in a preamplifier such as M-

Audio’s $180 MoblePre USB.

To add a Real Instrument track:

1. Click the Add Track button, or choose Track > New Track.

2. In the New Track dialog, click the Real Instrument tab.

3. Select an instrument category from the Category list, then select an instrument from the

Instrument list.

4. Select the input format by clicking either the Mono or Stereo format button, then choose

the input channel from the Input pop-up menu. If the instrument you are recording has a

single input, choose the Mono format. If the instrument has left and right inputs, choose

the Stereo format.

Getting Ready to Record

Once you have connected your instrument and added a track to record in, there are a few things

to check before you start recording:

1. Make sure the microphone or instrument is connected properly and is working.

2. Make sure the correct audio drivers are selected in the Audio/MIDI Interfaces pane of

GarageBand Preferences.

3. Open the Track Info window to make sure the instrument has the instrument and effects

settings you want, and is using the correct input channel (or pair of channels).

4. Sing or play a few notes and watch the track's level meters in the track mixer to make sure

the track is receiving input, and isn't clipping. If the red dots at the right of the level meters

(called clipping indicators) light up, try dragging the volume slider to the left a little to
