Looping and Loop Processing
Looping and Loop Processing
Looping is a technique that can extend a sound’s length indefinitely. It is based on the
fact that many sounds start off with a complex attack transient, then settle down to a
comparatively steady sound.
Although an Emulator X sample can have multiple loops, most sampled instrument
presets only use a single loop. Multiple loops are generally used for special effects or
for the TwistaLoop function as described on page 187.
Attack
Sustain
For an aural example of how looping works, listen carefully to a plucked guitar string.
The first part of the sound consists of a complex mixture of pick noise and several
harmonics; then the string quickly decays down to a steady repetitive tone. Since the
latter part of the waveform is repetitive, you can mark off a loop of the repetitive
section, and play that looped section for as long as the key is held down. After playing
to the end of the loop, the sound jumps back to the beginning of the loop and plays
through the loop again. This process repeats until you release a key. If the “Loop-in-
Release” function is On, the sound continues to loop until the volume dies away.
