Loop Sync only works with phrases that are set for looped playback.
If you’re using Loop Sync to create a multi-phrase loop performance from
a blank slate—that is, you start with three empty phrases—the first phrase
you record will determine the loop playback length. However, if you’ve
recorded or imported audio into a patch’s phrases before turning on Loop
Sync, the loop playback length will be determined by the overall length of
the longest recorded/imported phrase.
After the longest phrase has been defined, Loop Quantize behaves a little
differently than discussed previously. With Loop Sync off, we used Loop
Quantize to create phrases that match the measure length of a reference
phrase. When Loop Sync is on, however, the longest phrase’s overall length
becomes the reference for Loop Quantize.
When Loop Sync is on—and the guide is off—Loop Quantize is enabled
during phrase recording when:
another phrase contains audio (it doesn’t have to be playing).
that phrase is set for looped playback (its One Shot parameter is set to
LOOP).
When these conditions are met, Loop Quantize ensures that new phrase
recordings don’t exceed the length of the longest phrase.
In practice, once you’ve determined the overall loop playback length
by recording or importing a phrase, you don’t need to think about Loop
Quantize when using Loop Sync. It does all the phrase adjusting under
the hood, automatically closing a newly recorded phrase—and switching
to overdubbing—when its length matches the longest phrase.

Loop Quantize with External Sync
When the RC-50’s set to receive a MIDI clock signal at its MIDI IN jack, its
phrases and guide can be synchronized to MIDI clock messages sent from
an external MIDI device, such as a drum machine, MIDI sequencer, or even
another RC-50.
When synced externally, the RC-50’s patch tempo follows the incoming MIDI
clock tempo, and phrase actions (recording and playback) can be controlled
via incoming MIDI start and stop messages.
When the RC-50 is receiving MIDI clock messages, Loop Quantize is always
enabled. The patch tempo—determined by the MIDI clock signal—provides
the measure length reference for Loop Quantize.
In actual use, you’ll find that using Loop Quantize with external sync
behaves essentially the same as using Loop Quantize with the guide.
The only difference is that the starting of recording/playback is
initiated from the external device instead of the RC-50 itself.
To learn about syncing the RC-50 to an external MIDI device, see
Chapter 8 in the RC-50 Owner’s Manual.
