Exploring Tracks and Regions
As you can see, playing a song in the Timeline is easy. Let's take a moment to examine what makes up the song in the Timeline.The song 1-1 Eyewitness contains eight tracks.


Real Instruments
Purple regions are the Real Instrument parts. They are exactly what the name suggestsparts recorded from real instruments.Real Instrument parts can be recorded into GarageBand through a microphone, guitar, or keyboard that is plugged into the microphone jack on your computer. You can also record Real Instrument parts through other input devices that you connect to your computer. You will learn more about recording Real Instruments later in this book.For the 1-1 Eyewitness song, I recorded three Real Instrument parts using a synthesizer as the instrument (Female Basic, String Ensemble, and Wind Chime).

Software Instruments
Software Instruments are recorded performances that are more flexible than Real Instruments because they use professional MIDI samples. Software Instruments utilize some of the same powerful music editing tools found in Apple's professional recording software, Logic.NoteMIDI stands for Musical Instrument Digital Interface. It's an industry standard that allows all devices, such as synthesizers and computers, to communicate with each other.Software Instrument regions are green and are recorded using a USB music keyboard, a MIDI synthesizertype keyboard, the GarageBand onscreen keyboard, or Musical Typing using the GarageBand software and your computer's keyboard as the MIDI instrument. Once the notes for the Software Instrument region are recorded, you can change the sound of the instrument that plays the notes, fix the timing, notation, and velocity, or change the pitch of the region to a different key.For this song, I recorded two Software Instruments located in the top two tracks in the Timeline.

Apple Loops
GarageBand also comes with over 1000 prerecorded Apple Loops. These loops are regions that contain either digital recordings of real instruments or editable MIDI notes. Just like Real Instrument or Software Instrument parts you record yourself, Real Instrument Apple Loops are colored blue, and Software Instrument Apple Loops are green. Prerecorded loops can be used to accompany the other instrument tracks and are incredibly useful for adding tracks with instruments you can't play and record yourself. These loops are like your backup band.For the Eyewitness 1-1 song, I used prerecorded Apple Loops for the percussion section. The Bongo and Shaker regions are blue, which means they are a digital recording with notes that can't be edited.[View full size image]
