Parameter Tempo Sync Features
The following control knobs have enhanced features for Tempo Sync allowing for perfect beat sync even
when the tempo source changes.
Loop Play-Start Point: When using Tempo Sync, the minimum length of audio that can be played out
is 1 beat so, the Play-Start Point will display in beats allowing you start playback from 0 beats up to
Loop Length minus 1 beat.
For example, if you recorded an 8 beat loop, this will range from 0 to 7 beats. Changing the Play-
Start Point during Playback will apply the next time the Loop comes around and will maintain
perfect beat sync with the Tempo Source.
Loop Play-Length: When using Tempo Sync, the minimum length of audio that can be played out is 1
beat so, the Play-Length will display in beats allowing playback lengths of 1 beat up to the Loop
Length. For example, if you recorded an 8 beat loop, the Play-Length will range from 1 to 8 beats.
Changing the Play-Length during Playback will apply the next time the Loop comes around and will
maintain perfect beat sync with your Tempo Source. Of course, new Play-Lengths that don’t evenly
divide the total Loop Length will cause the loop to “walk” the downbeat, thus creating interesting
poly-rhythms against an existing pattern.
Speed / Varispeed: When using Tempo Sync, the Looper always loops about the current Play-Length
number of beats in the originally recorded time base, regardless of changes to the Speed. Thus, for
slower speeds the loop length will be truncated, and for faster speeds the loop will play through
more than once. For example, if you record an 8 beat loop at 1x, then play out 8 beats at a Speed of
50 (.5x), the Looper will loop beats 1-4. Alternatively, if you choose to play at a speed 150 (1.5x),
the loop will complete one full cycle of 8 beats, then a half cycle of 4 beats, and continue to loop this
1.5x pattern against the original time base. Please note that this Speed-based sync feature is
temporarily disabled while Dubbing, allowing you to dub through an entire loop, and once you exit
Dub mode moving back to Play, this sync feature will resume. This ensures that the Looper always
maintains perfect timing with external audio, drum machines, etc. while providing the option to
layer expressive pitched and poly-rhythmic patterns or even minutely controlled drifts that always
come back on the downbeat.
