Whether or not any track is sync'd to measure, every time you start the sequencer, it will start
keeping track of the measure count. If the length of measure is set to 16 steps (UTILITY Opt., Option
#1), the sequencer will start counting from 1 to 16, and after reaching the end of the 16th step, it will
be reset, i.e. started from 1 again. It's like you yourself might be counting quarter notes: one two
three four, one two three four, etc. in a steady rhythm, with the difference that measure is counting
16th notes. This recurring count continues until the sequencer is stopped.
Sync'ing a track to measure means that the track's restarting will be bound to the restarting of the
measure count: when the measure has counted its last step, it will be reset to the beginning, and any
track that is sync'd to measure, will be reset as well, i.e. started from the beginning.
5.4.1. Sync to Measure in phrase mode
By default the tracks are not sync'd to measure, so the setting has to be enabled separately for each
track on the DIVIDER page (GPK5–7 for 'yes' or 'no'). If no track is sync'd to measure, they all will run
independently of each other, and are relative only to the tempo setting.
Fiddling with the divider/timebase settings on the DIVIDER page can bring the independent tracks
completely out of sync with each other. Sometimes that's just what you want, but if you have a
number of tracks that are out of sync and you want them sync'd, this can be done with setting 'Sync
to Measure' to 'yes' on the DIVIDER page. If measure length is 16 steps, every track that is sync'd to
measure will be reset and started from the beginning at the time when the measure count resets
back to the beginning, no matter how long the tracks are and where their relative cursor position is.
Tracks that are shorter than measure length will repeat on their own until the measure count is reset,
and the shorter-than-measure tracks will reset at that point, just like any other track that is sync'd to
measure.
Measure lenght is 16 steps, a track's length is 6 steps, and the track is sync'd to measure.
This track will repeat twice on its own, quite independent of the measure, because two times
6 is 12 steps, i.e. shorter than 16 steps, which is the length of the measure. However, during
the third iteration of the track, the measure is reset before the track can reach its end; the
track is reset together with the measure count. Thus, this shorter-than-measure track will play
two times and four steps before it is reset (6 + 6 + 4 = 16). A track that is longer than
measure will be cut short, if it is sync'd to measure.
Naturally sync'ing to measure doesn't guarantee that the sync'd tracks will be in sync all the time,
only that they will be simultaneously started from the beginning every time measure count starts
from the beginning. In other words, each track is sync'd to the measure, not to each other. Each
sync'd track will hear the reset command at the same time, but after the reset they will go they own
separate ways again, according to their individual length and divider settings, until measure reset
forces them to start from the beginning again. This allows you to effect repeating patterns of
asynchronous play.
In the example below, measure is set to 6, and tracks 1–4 are sync'd to measure. Tracks 1
and 2 will be cut short because they're longer than measure, and tracks 3 and 4 will repeat
part of their content before measure count restart resets them.
