70 Chapter 10 Mixing and Adding Effects
Turning Effects On and Off
You can turn individual effects on or off (turning an effect off temporarily is called
bypassing the effect). This has several advantages: it lets you hear how each effect
changes the sound of your music, and lets you see which effects have the greatest
impact on your computer’s performance.
When you turn off an effect, the effect’s current settings are retained, so any
adjustments you have made are not lost.
To turn an effect off:
m In the Effects section of the Track Info window, click the checkbox next to the effect.
Click the checkbox again to turn the effect on again.
Choosing Effect Presets
Each effect includes several presets, which let you easily set the effect’s parameters to
achieve a particular sound.
To choose an effect preset:
m Choose the preset you want from the Preset pop-up menu to the right of the effect’s
row.
Editing Effect Presets
Some effects, such as the equalizer and amp simulation effects, include groups of
settings called “presets,” which you choose from the effect’s Preset pop-up menu. You
can adjust effect presets to fine tune the effect, and save your own presets to use with
other instruments or in another song.
To show the Preset window:
m Click the Edit button (with the pencil icon) to the right of the effect’s row.
The effect’s Preset window appears. Each preset setting has a slider, button, or other
control, and each control is named to indicate what it controls.
To adjust an effect preset:
m Drag the sliders in the Preset window to adjust the settings in the preset.
When you adjust an effect preset, it appears as “Manual” in the pop-up menu, so you
know you’ve changed it from the original preset. You can go back and forth between
your Manual settings and other presets to compare them before saving the new preset.
