Check my project I did last year. Stockwatch takes values of the stock market and translates them in realtime into music and also improvizes on it. YOu can dowwnload it here http://www.filemojo.com/022716332178181/Stockwatch.zip
It uses the stockwatch example as its base. The paatch has an mxj-object. With some tweaking, you could arrange to get other data I guess.
Can you tell more about your project btw, I am going to do research about using complex data on composition, so I would like to know how different composers look after this way of composing.
