I am giving for a try the following link to an External I wrote for MSP 6, which implements the Dynamic Stochastic Synthesis algorithm invented by Iannis Xenakis. The external will be named gendynix~ . Any remarks are welcome.
By the way, this external has already be used as a synthesis tool for the piece "110110" that was played at ZKM / Karlsruhe on June 2nd 2012. A stereo version of this piece can be listened to in the Audio section of my website.
