No, generally speaking, that's not possible. (Unless you're an experienced hacker who is willing to spend (read: waste) weeks or even months reverse-engineering the entire system.)

What makes you think that changing the software will make it compatible? What software do you want to use, what features do you need?
And why did you post this on an Arduino forum?
because arduino is the tool and the software to make a controller compatible with ableton ... like 8 audio chanels and u can configurate the sounds on a imput way across the ableton
I don't understand what you want to achieve, and I don't think you do either. Could you please send us a link to the exact keyboard you have, and tell us exactly what you want to do with it.
