Loop Quantize; To Use Loop Quantize - Boss RC-50 Owner's Manual

Loop Quantize

The function that enables you to adjust the length of the phrase you
are going to record automatically is called "Loop Quantize."
The timing at which you stop recording a phrase is very important in
order to create a looped phrase of the correct length. In the past, the
ability to stop recording at the right moment required much practice
using the pedals to get it right.
When Loop Quantize is in effect (when the LOOP QUANTIZE
indicator is lit), then even if there are any minor discrepancies in the
timing of the end of a recording, the phrase length is automatically
corrected based on the patch tempo and guide beat, enabling you to
create phrases that loop properly and have the correct measure
length.

In addition, when using Multi mode with Loop Sync on, if Loop
Quantize is in effect (if the LOOP QUANTIZE indicator is lit),
recording automatically stops when the phrase reaches the same
length as the previously recorded phrase, allowing you to record
three phrases, all of exactly the same length.
Example of Recording Using Loop Quantize
Using Single mode, the three phrases Melody A, Melody B, and the
bridge are recorded at the tempo set beforehand.
In this situation, if Loop Quantize is in effect, it enables you to record
with measure lengths completely correct, even if each recorded
phrase contains a different number of measures, so after recording,
phrases play back smoothly in time with the tempo when you play
back loop phrases or switch phrases during playback.

To Use Loop Quantize

Single Mode
Switching the guide on or off determines whether or not Loop
Quantize can be used.
When the guide is on (when GUIDE LEVEL is set
to anything other than OFF):
You can use Loop Quantize.
The phrase length is automatically corrected in accordance with the
patch tempo.
At this time, the LOOP QUANTIZE indicator lights.
When the guide is off:
You cannot use Loop Quantize.
The phrase length is determined according to the timing at which
you end the recording (with playback or by stopping).
At this time, the LOOP QUANTIZE indicator is off.
When Synchronized Performance (p. 77) is used to synchronize
the RC-50 to an external MIDI device's tempo, Loop Quantize is
enabled for use, just as when the guide is switched on.
At this time, the LOOP QUANTIZE indicator lights.
You cannot set the tempo for phrases that are looped over an
interval shorter than the minimum recording time
(approximately 1.5 seconds).
Multi Mode
When Loop Sync is set to OFF:
As in Single Mode, whether or not Loop Quantize is enable for use
changes according to whether the guide is on or off.
If, however, in addition to the phrase you are about to record, a
recorded phrase meeting both of the conditions below is being
played back, the phrase length is automatically adjusted in
accordance with the patch tempo.
• Tempo Sync is ON
• One Shot (p. 52) is set to LOOP
At this time, the LOOP QUANTIZE indicator lights.
When Loop Sync is set to ON:
As in Single Mode, whether or not Loop Quantize is enabled for use
changes depending on whether the guide is on or off.
If, however, in addition to the phrase you are about to record, there
is a recorded phrase with One Shot (p. 52) set to LOOP, the phrase is
recorded with the length automatically set to the same duration as
the loop time when Loop Sync (p. 28) is on.
At this time, the LOOP QUANTIZE indicator lights.
