Yamaha QY100 Owner's Manual page 150

The " Gate Time " parameter increases or decreases the gate times
(length) of all notes affected by the swing parameter. The range is from 0%
to 200%. The "Gate Time" parameter sets the ratio between the shorter
and longer gate time values. A setting of "100%" maintains the original
relationship between the notes, lower values produce a narrower gate time
range, and higher values produce a broader gate time range.
After setting the parameters as required press [ENTER] to execute
the Quantize job. The metronome icon will appear on the display while the
data is being processed, then "Completed !" will appear briefly when the
job is done. Press the [EXIT] button to return to the job list, or a mode but-
ton to go directly to the selected mode.
