Percent Alteration Continuous Data
How to get there
Click the MIDI Tool 
. Select a region of measures. (If you’re editing only
a single staff, double-click the highlighted area to enter the MIDI Tool
window.) Specify the MIDI
data type you want to edit by choosing Continuous Data from the MIDI Tool
Menu. If you’re in the MIDI Tool window,
select the region you want to affect by dragging through the "graph"
display area or by selecting the handles of individual notes whose MIDI
data you want to edit. Choose Percent Alter from the MIDI Tool Menu.
What it does
This dialog box’s function is to change the continuous data value of every note in the selected region by a percentage of its current value. Because it changes the data of every selected note by a percentage, the Percent Alter command preserves the relative proportions of the existing values.
When you select Continuous Data from the MIDI Tool Menu, a dialog box appears in which you can specify the MIDI controller or wheel data you want to edit—pedaling, patch changes, pitch wheel, and so on. In this case, the number in the Percent Alteration text box specifies a percentage by which you want that controller’s values multiplied for all the selected music. The Percent Alter command isn’t relevant if you’ve specified a non-continuous controller such as the sustain pedal or a patch change; it may be useful, however, if you want to increase the degree of pitch bend or monophonic aftertouch by a uniform amount for every note in the selected region.
