Looking pretty good man, I am actually in the process of designing an Ableton controller as well, I was considering the keyboard hack method before I read this. I'm glad I am seeing the pitfalls now, anyways my controller will be more of a dedicated efx controller that I would use in tandem with a mixer component i want to build afterwards. Anyways, I can't wait to see how it ends up looking I'll be sure to check it out, maybe you could post a vid of it in action. ryan
