Hello everyone!

I'm quite new to this board and to Pd in general, but have been programming for a few months now. I was wondering if anyone has information about a stochastic synthesis program called GenDyn that Xenakis wrote in the 1990's. Two artists that I quite like, Russell Haswell and Florian Hecker, use this software, but I have been unable to locate a copy of this software anyplace. Does anyone have information on this software or an equivalent program?
