Change
The Change function is used to modify attack velocities, release velocities, or the values of any
existing controller data on the current track. A static change of values can be made as well as
having the change take place over a region of time.
Change can not modify or add data that doesn't exist on the current track. If you hear Note
events played back on a track, then you know there is an attack and release velocity value for
each one, and the effect of the Change function can usually be easily detected. Controller values
are sometimes more difficult to change since there can be inconsistent gaps of time between each
controller event.
Scale: 0% to 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 to 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 PosRamp, 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 NegRamp to achieve the opposite dynamic effect of PosRamp. NegRamp
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, beat, and tick defined in the To parameter.
