Building a Trainer for drummers

Hi all!! I'm building a electronic drum based on Arduino. All about piezo and others are ready and working great.

But now what i want to do is build a trainer based on this drum. For now each patch have a little led that shows when i hit each patch.

So now using some drum program that generates a drum track, load into a VB application or similar and switch each patch's led at the correct squence and time. 8)

Some program who save the track file in a XML/INI with the squence and time to load and decode it with my VB application?

Best Regards Frank

I would use a MIDI to LED circuit, something like:- MIDI Glockenspiel then you need only play the MIDI file and have the drum pads light up in the same sequence as they should be played.
