About The Tempo And Time Signature; Setting The Tempo - Boss RC-20 Owner's Manual

About the tempo and time signature

The RC-20 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.
About automatic tempo settings
In the following cases, the tempo of the phrase will be set automatically after
it is recorded.
• When you record a performance from a device connected to the AUX IN jack
without setting the tempo
• When you record a performance from an instrument or microphone
connected to the INST or MIC jacks without setting the tempo
* The automatic tempo setting is calculated with a time signature of 4/4. If you are recording a
phrase whose time signature is different, you must re-set the correct tempo after recording.

Setting the tempo

If you are recording a performance from an instrument or microphone connected
to the INST or MIC jacks, set the tempo before recording.
You can change the tempo for playing back the stored phrase.
* If you change the playback tempo, then store the phrase, the modified tempo will be stored.
If you do not save it, the tempo change will be lost.
1. Turn the PHRASE SELECT knob to select the phrase track you wish to use.
If you are recording a new phrase, select the track you wish to record.
2. Press the TAP TEMPO button several times at the desired tempo.
The tempo will be set according to the intervals at which you press the button.
* The tempo can also be set by pressing the right pedal instead of the TAP TEMPO button.
However, the right pedal cannot be used while a phrase is playing.
* There are limits on how far the tempo can be changed.
* If you wish to record a new phrase at the same tempo as the previously-selected phrase,
press the TAP TEMPO button / right pedal once.
* By starting recording without setting the tempo, you can create a loop phrase without
using the Loop Quantize function.
NOTE
24
It is not possible to set or change the tempo while a phrase is stored
in temporary memory. If you are unable to set or change the tempo,
delete (clear) the phrase stored in temporary memory, and try the
operation again (p. 22).
