Midi importer is a script that allow to synchronize blender events with musical events contained in a midi file.

WHAT DOES THIS SCRIPT DO ?

When launched, this script open a file selector through which you can choose the midi file you want to synchronise your animation with.Then,

It load a midi file,
create an ipo for each different sound used in the drums part (channel 10),
fill in these IPO with NOTE ON and NOTE OFF midi event encountered on drums tracks until the last frame of your animation

Events are created into IPO named "IPONoteXX" where XX is the note number.
Synchronisation operates with respect to the frame/sec parameter of your animation but tempo changes are not yet taken into account.

HOW TO INSTALL THIS SCRIPT ?

Copy midi_import.py file into the ".blender/scripts" directory of your Blender installation.
In a Script window, go to the "Script" menu entry and perform an "Update Script"
