20 Editing MIDI Events in the
Transform Window
The Transform window allows you to define a set of
conditions and operations that are used to select, and alter,
specific MIDI events.
The Transform window is so-named because it transforms MIDI events—based on
conditions, operations, and values chosen by you—into different types of events, or
events with different values.
The Transform window is immensely powerful, and is the ideal tool for edits that would
otherwise be impossible (or at least, incredibly tedious). As an example, imagine an
orchestral project that has been sent to you to work your magic on. The individual
violin and viola parts were recorded with a different string library, and feature
aftertouch information (in 200 MIDI regions!) that introduces a weird pitch modulation,
and some sample layer switching artefacts when played with your string samples. After
looking at this aftertouch information, you discover that only a small range of values
are causing the problem. You have a few options; edit your sampler instruments,
manually strip out 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 Transform window. Option three sounds like the way to go!
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 freely 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. For details, see the information on the
“Transformer Object” on page 918.
