Logic Pro X keyboard command of the day. #LogicProX @StudioIntern1

  Apply Transform User Preset 20 to selected Events

Transform User Presets are basically macro operations that can be performed on MIDI events. Repetitive and difficult editing operations can be applied with a simple command.

With 30 possible user presets, referenced by number, it is likely that a list of transforms would be required to make any practical use of the “apply by number” commands.

Currently there are 18 presets defined, with some useful (and not so useful) demonstrations. All good starting points.

MIDI Transform window overview — Logic Pro X

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.
