76 Chapter 10 Mixing and Adding Effects
To transpose part of a project to a different key:
1 Choose Track > Show Master Track.
The master track appears at the bottom of the timeline.
2 From the pop-up menu in the master track’s header, choose Master Pitch.
The master pitch curve appears in the master track.
3 Click the box to the left of the words “Master Pitch” to turn on the master pitch curve.
4 Click the master pitch curve at the point you want to change the pitch of the project.
5 Drag the control point up or down to the new key. Unlike with volume and pan curves,
the control points on the master pitch curve move in discrete steps of a semitone.
Note: When you transpose a project to a new key, Real and Software Instruments (both
those you’ve recorded and loops) are transposed. Any audio files added from the Finder
are not transposed.
Using Effects
Effects let you shape and enhance the sound of your music in a variety of ways. Anyone
who’s listened to popular music on the radio, or listened to the soundtrack of a movie,
has heard the different effects used in contemporary music. GarageBand includes a
complete set of studio-quality effects that you can use on individual tracks or the
overall project to shape the sound of your music.
Types of Effects
GarageBand includes the following types of effects:
Equalization (EQ): EQ is a powerful and versatile effect that lets you change the level
of selected frequencies. You can use EQ to make both subtle and dramatic changes to
your projects. EQ is likely the most commonly used effect in popular music.
Dynamics: Dynamics effects, which include compressors and noise gates, let you
control the volume of your music over time.
Reverb and Echo: Reverb and echo are both time-based effects. Time-based effects
store a copy of the sound and play it back at a later point in time, creating a sense of
space.
Modulation: Modulation effects, which include chorus, flangers, and phasers, build on
the time-based effects by shifting or modulating when the copied signal plays back.
They can also involve detuning the copied signal relative to the original.
Distortion: Distortion effects, which include amp simulation and overdrive (and, of
course, distortion!), change the tone of the original sound to recreate analog or digital
distortion.
