Hello,
To pt3r: There is no MIDI OUT jack, but using a processing applet and some Arduino code, you can use the shield as a midi controller. This setup will be a demo program. If you think that there will be enogh people interested in a actual MIDI OUT jack, I can add one. Thanks for catching this, I updated the my first post. 
Thanks
To Peter Knight: Hello,
It would be great if you could help me inplement an idea. I am not the greatest coder, so Im getting my friend to Write the demo programs. With this shield setup,there will be two unused pots. I am interested in what you think would be a cool function to add to the board. I was think 2 second volume envelopes that would each control one oscillator. How hard would this be to implement?
Thanks
To all: I will continue to add all updates I make to the shield on this thread and my blog.
