Offset
Adds a fixed value to the Rate-adjusted velocity values. A setting of 0 produces no change. Range below 0 reduce the
velocities, and Range above 0 increase the velocities. When the Set All parameter is set to something other than "Off," this
parameter cannot be changed.
Range: -127 – +127
Execute
Executes the Job to the MIDI sequence data.
Gate Time
This Job alters the gate times of a specified range of notes.
NOTE Gate time changes are calculated as follows:
Adjusted Gate Time = (Original Gate Time x Rate) + Offset
If the result is 0 or less, the value is rounded off to 1.

Operation
Set All
Sets the gate times of all target notes to the same fixed value. When set to "Off," the Set All parameter has no effect. When set to
a value other than "Off," the Rate and Offset parameters are unavailable.
Range: Off (0), 001 – 9999
Rate
Determines the percentage by which the gate time of the target notes will be changed. Range below 100% shorten the notes,
and Range above 100% lengthen the notes proportionately. When the Set All parameter is set to something other than "Off," this
parameter cannot be changed.
Range:
0% – 200%
Offset
Adds a fixed value to the Rate-adjusted gate time values. A setting of 0 produces no change. Range below 0 shorten the gate
time, and Range above 0 lengthen the gate time. When the Set All parameter is set to something other than "Off," this parameter
cannot be changed.
Range: -9999 – +9999
Execute
Executes the Job to the MIDI sequence data.
