musicXML

I wanted do work on some project involving MusicXML.It is a very interesting topic to look into. i found tons of stuff there. I practically listen to music 24 hours a day. Huge fan of music of all sorts. Ranges from Richard Wagner to Dimmu Borgir.

but for musicXML the ideal music would be the instrumental music .MIDI would be best repersented by XML.
I looked upon a few musicXML technologies and a few softwares. There are 2 minor Problems here.
1) The Software does everything for you.It converts MIDI to XML and XML to MIDI automatically. So there is very little for you to do.
2) Most of the Demo Software wont Allow you to convert MIDI to XML .and they Cost 600$ for the full version.

They have a humongous Advantage. The software is very easy to use.And altering the MIDI is easy both interms of XML and the software.

But i dont have the resources to Play around with musicXML and come up with some fancy project.For now , I am thinking of something do with a Music Database.
