[PD] An abstraction : markov finite state machine

[Koray Tahiroglu]

Hello Alex,
As a part of my doctoral studies/research I am developing some  
interactive systems where the performer can improvise with it. and  
the system responds in real-time to the performer's responds. All the  
analyzes are based on Markov chain probability methods. I used python  
for the markov based stochastic analyzes and PD to generate sounds. I  
will upload them somewhere whenever I settle down a bit. I am  
planning to develop it further, I can bug you later to hear your  
experiences.

Koray.
