MIDI Transform window
Logic Pro MIDI Transform window overview
The MIDI Transform window is so-named because it transforms MIDI events—based on
conditions, operations, and values you choose—into different types of events, or events
with different values.
The MIDI Transform window is a powerful tool for edits that would otherwise be impossible
(or tedious). For example, imagine an orchestral project that has been sent to you for
editing. The individual violin and viola parts were recorded with a different string library.
Two hundred MIDI regions contain aftertouch information that introduces an unpleasant
pitch modulation, and some sample layer switching artifacts when played with your string
samples. After looking at this aftertouch information, you discover that only a small
range of values is causing the problem. Your options:edit your sampler instruments,
manually remove all aftertouch information (region by region, or globally, thus losing the
performance benefits that the aftertouch information provides), or alter the problematic
values in the MIDI Transform window.
A number of preset transform sets are available for many common editing tasks. These
may be all you’ll ever require, but should the need arise, you can create and save your own
transform sets, and recall them later.
Tip: The Environment contains a similar transformer object that you can use for real-
time transformations of MIDI events. See Transformers in the Logic Pro Environment.
