96 Chapter 9 Tutorial 7: Mixing and Adding Effects
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.
Reverb: Reverb simulates the natural reflections of a sound in a surrounding space. It
can add definition and presence to voices and instruments, add ambience to a sound,
or simulate different rooms and other acoustic environments.
Stompboxes: Electric Guitar tracks include special stompbox effects that re-create the
sound of famous guitar effects pedals. Stompbox effects include echo, chorus,
overdrive, flanger, and other effects.
Effects can either be track effects, send effects, or master effects. Track effects modify
the sound on an individual (Real Instrument, Software Instrument, or Electric Guitar)
track. Send effects send part of the sound from a track to the effect on the master track.
Each Real Instrument, Software Instrument, and Electric Guitar track includes Echo and
Reverb send effects; you can control how much of the sound is sent from each track in
that track’s Track Info pane. Master effects modify the overall sound of the project,
affecting all tracks.
Adding Effects to a Track
Each Real Instrument and Software Instrument track has a set of effects, which include
compressor and Visual EQ effects, as well as echo and reverb send effects. Real
Instrument tracks also include a gate (noise gate) effect. You can adjust a track's effects,
and add effects, in the Track Info pane.
The master track includes its own effects. You can adjust the master effects and add
one more effect to the master track in the Track Info pane.
To add an effect:
1 Click the Track Info button, or choose Track > Show Track Info to show the Track Info
pane.
The Track Info pane opens to the right of the timeline.
2 Click Edit to show the track effects.
