MIDI AE 1.1 A small application software that makes a bridge between MIDI controllers and scriptable applications for MaxOS X.
Some of the popular softwares running on MacOS X, such as Safari, Mail, iCal, iPhoto, iTunes, QuickTime Player, Finder, and so on, are scriptable, that is, controlable by AppleScript program that independently runs on MacOS X. This program, MIDI AE, enables you to control a scriptable application with keys, knobs and sliders of your MIDI controller by converting MIDI messages to a short AppleScript program and executing it.
Hint: Here is another freeware named MidiPipe for more general purpose of MIDI I/O including a trigger of AppleScript from incomming MIDI message, but the feature has some different points.
