12 Recording a guitar or vocal performance to create a loop phrase On the RC-20XL, the process of recording an additional performance while a recorded performance plays back is called overdubbing .

14 Recording a phrase from CD/MD to create a loop phrase You can create a loop phrase by recording a performance from a CD or MD connected to the AUX IN jack. For example, you can record phrases from a sampling CD and overdub guitar or vocal onto it, or even record an entire song from an audio CD and use it for practicing.

21 Using the RC-20XL for practicing—Phrase Trainer * If an effect such as reverb has been applied to the sounds localized at the center, it may not be possible to erase the sound completely.

24 Playing back in various ways Using the pedal to switch phrases (Phrase Shift) While a phrase is playing, you can press a pedal switch connected to the PHRASE SHIFT jack to switch to the phrase track of the following number.
25 Playing back in various ways • When you switch to a phrase set to One-Shot Playback, the phrase is played to the end, and then playback stops. • If you use Phrase Shift during One-Shot Playback, the phrase is played to the end, then the unit switches to the next phrase.
26 Playing back in various ways Play back a phrase backward (Reverse Playback) Playing a recorded phrase from the end toward the beginning is called “reverse playback.” The result is similar to playing a tape in reverse. By pressing the REVERSE button, lighting its indicator, you can use reverse playback.
