Getting information from Tracker music

Hi guys. I'm working on my final degree project, which is an AR live virtual music visualizer but i'm stuck in the part of getting data from the music files.

The idea is the following:

1. Load a tracker song (the supported formats) or a .mid file (I mannaged to play .mid songs although they're not supported in Unity, thanks to n-yoda)

2. Get data from the tracker and midi files, such as played notes, type of instruments played... just like this midi to text parser.

3. Send the information to the virtual artists, so they can play the song with high precission because they have the music information such as when to play the notes.

4. Use Vuforia or the new android ARCore (actually the idea for my project came from there) to put the artists wherever you want and start the show.

Quite easy, right? Well, actually i'm in the early second point, and that's why i'm here. I can't find a way to get the information from the module files, so far i could just make the typical audio visualizer (like this one) with cubes using the .GetSpectrumData() function, which is not what i want. Can you guys help me? Any comment or hint is highly appreciated.
