Chapter 5 MIDI Regions 55
The Transform Window
The Transform window is a very powerful editor that can be customized to build your
own preset transform operations. It can be used for dramatic MIDI data changes, or for
subtle alterations. As an example of the latter, it could be used to reduce the amount of
filter modulation—with values ranging between 97 and 105—by a fixed percentage.
While this type of change could be performed in other editors, it would need to be
done on each individual modulation event. The Transform window allows you to
quickly achieve the same result on multiple events.
To best illustrate how the Transform window can be used:
1 Please select the “Bass” MIDI Region (between bars 25 and 29) on track 1.
2 Create a cycle from bar 25 to bar 29.
3 Open the Transform window via the Windows menu, or by pressing Command-4.
4 Select the Reverse Pitch preset from the pull-down menu, to the top left of the
Transform window.
5 Press the Play button on the Transport window or use the key command, and listen to
the part a couple of times.
6 While the MIDI Region is cycling, press the Select and Operate button in the Transform
window, and listen to the results.
7 Use the Undo function to return the MIDI Region to its former state.
8 Please experiment with the other presets and buttons, ensuring that you Undo
between each process.
More information about the Transform window can be found in the Logic reference
and Onscreen Help system.
