Phrase Memory
A combination of a track with a rhythm pattern is called a
“phrase memory.”You can store up to 99 dierent phrase
memories.
Rhythm
The rhythm consists of four divisions: INTRO, PTN 1, PTN 2,
and ENDING. Additionally, the PTN 1 and the PTN 2 each have
their own ll-in.
Looper
The looper consists of two divisions: TRK 1 and TRK 2. You can
use this to record and play back the sound of your guitar or
bass.
SYSTEM
This contains overall settings for the entire RC-10R.
&For details, refer to “Parameter Guide (English)”(PDF).
How the RC-10R Is Organized
“Recording” and “Overdubbing”
In this manual, “recording”refers to the rst recording that
you make on an empty track, and “overdubbing”refers
to the second and subsequent recordings that you layer
onto the rst recording.

Recording a TRK 2
Just as you can switch the rhythm between the PTN 1
and the PTN 2, you can also switch between the looper’s
TRK 1 and TRK 2 during recording or playback. This lets
you create a backing track that contains dierent chord
progressions appropriate for the song’s playback parts.
1. During TRK 1 recording, overdubbing, or
playback, hold down the [RHYTHM] switch for
two seconds or longer.
The rhythm switches to playing the PTN 2, and at
the same time the looper switches to recording the
TRK 2.

can also switch the TRK 2 between overdubbing and
playback.
MEMO
