The following youtube link might be of interest to fellow Lisp and algorithmic composition geeks. In the video I show how I can control my slippery chicken algorithmic composition software via an interface created in Max. The score is then generated and displayed on-thy-fly, using the musician's favourite configuration. Communication between Max MSP and Lisp is done via OSC.
The OSC code will be released in the next version of slippery chicken (which could be very soon if anyone's particularly keen).
