About the tempo and time signature
The RC-20XL allows you to set the tempo and time signature separately for each
phrase. These settings also determine how the guide tone will play, and how loop
quantization will occur. This means that if the tempo and time signature are correctly
set before recording, it will be easy to create a correct loop phrase.
* The default time signature is 4/4. If you are recording a phrase with a 4/4 time signature, it
is not necessary to set the time signature.
What is Loop Quantize?
The timing at which you stop recording the phrase is very important in order to create
an accurately looped phrase. When using devices other than the RC-20XL, it was
necessary to become skilled at operating the pedal, through much practice.
The RC-20XL, however, has Loop Quantize function that automatically corrects the
length of the phrase by referring to the information in the Tempo settings so that an
accurately looped phrase can be created even if recording is stopped at a slightly
inaccurate timing.

* Loop Quantize is valid only when you have set the tempo before recording (the LOOP
QUANTIZE indicator will be lit). If you have not set the tempo before recording, or during
overdubbing, the Loop Quantize function is not active (LOOP QUANTIZE indicator
extinguished).

About automatic tempo settings
When a phrase is recorded without a specific tempo setting, the tempo is then set
automatically after the recording is finished.
* The automatic tempo setting calculates the tempo premised on recording with a time
signature (beat) of 4/4 and four beats per measure.
If you are recording phrases with other beats, set the beat using the procedure on p. 34
before recording.
