2 Delay
Delay effects store the input signal—and hold it for a short
time—before sending it to the effect input or output.
Most delays allow you to feed a percentage of the delayed signal back to the input,
creating a repeating echo effect. Each subsequent repeat is a little quieter than the
previous one.
The delay time can often be synchronized to the project tempo by matching the grid
resolution of the project, usually in note values or milliseconds.
You can use delays for:
 Doubling individual sounds, making it sound like a group of instruments playing the
same melody.
 Creating echo effects, placing the sound in a large “space.”
 Enhancing the stereo position of tracks in a mix.
Delay effects are generally used as channel insert or bussed effects. They are rarely
used on an overall mix (in an output channel), unless you’re trying to achieve a special
effect, such as an “other worldly” mix.
This chapter describes the delay effects included with Logic Express:
 Echo (see below).
 Sample Delay (see “Sample Delay” on page 22).
 Stereo Delay (see “Stereo Delay” on page 23).
 Tape Delay (see “Tape Delay” on page 24).
