This nifty little tool converts MIDI notes to keyframes for your Blender composition. It reads out the notes from a MIDI file and converts this to a python script that runs inside Blender. There it will place keyframes at exactly the same position where a MIDI note was triggered.
Think about how much of a time saver this will be! Ever tried keyframing visuals under a breakcore or a jungle track? Well, good luck. With this tool it's just a matter of seconds and it uses the same source as how the audio file was generated in the first place. How much more in sync can it get?!
