are sometimes more difficult to change since there can be inconsistent gaps of time between each
controller event.
Scale: 0% – 20000%
The selected velocity or controller events' values can be changed to a percentage of the original
values determined by the Scale parameter. A setting of 100% has no affect. Values are scaled
lower with a Scale percentage set from 0% to 99%. Low values can be set higher using a Scale
percentage above 100% on up to 20,000%, although the maximum value of 127 can not be
exceeded for any velocity or controller type.
Offset: -128 – 127
Offset can be used alone or in conjunction with Scale to add or subtract a set amount to or from
the original (or scaled) values. Values for velocities can not be less than 1 or greater than 127.
Values for controllers can not be less than 0 or greater than 127.
As an example, to set all Velocities to a value of 55, you would set Scale to 0% (multiplies all
original values by zero) and set Offset to 55 (adds 55 to the product of the Scale parameter).
Mode: Constant / PosRamp / NegRamp
Set Mode to Constant to have values modified in a uniform fashion, as determined by the Scale
and Offset settings, for the entire selected region of time and range of values.
When the Change function is applied with Mode set to Positive Ramp, the selected velocity or
controller values will gradually change over the region of time, defined by the locations set for
the From and To parameters, from the original value to the new value determined by the Scale
and Offset settings. The first events being modified within the region will have little or no
change from their original values. The amount of Scale and Offset applied will increase as the
song approaches the Bar and Beat defined in the To parameter, where the full amount of
described change will occur.
You can set Mode to Negative Ramp to achieve the opposite dynamic effect of Positive Ramp.
Negative Ramp works in the same way, but the amount of Scale and Offset applied will
decrease from the full amount of change described by Scale and Offset to little or no change as
the song approaches the Bar and Beat defined in the To parameter.
