hi , can you explain how have you been using those chaotic equations for sound synthesis? have you been using them for the generation of sound itself? i been investigating about this.... in the stochastic synthesis as convieved by xenakis , stochastic laws are used to generate the succesive sample amplitudude values of digital sound. how can i use the numbers from one the pd chaos objects to determine sample amplitude values and the interpolation between them. how can this be achieved in pd? how can i calculate interpolation between samples? the idea is to use each couple of numbers (x-y axis?)from the chaotic attractor to control the lenght(how many samples?) of a segment (sucession of samples) and the last sample amplitude value of the segment... the sample values inside my segment are gonna be calculated by interpolation. any hint?

i been experimenting using chaotic equations and strange attractors to control some synthesis parameters, but i now im more interested of using them as a source for direct sound synthesis.
i haven't been implementing any of the gendy algorithms, but i've been using other kinds of chaotic equations for sound synthesis ...
the sources for my external are available on the cvs: http://cvs.sourceforge.net/viewcvs.py/pure-data/externals/tb/chaos/
for exampe i was trying to use the numbers resulting from those equations as a waveform using sig~ object with no luck. i just get some clicks . can anybody explain me how can i get sonorous signals from those numbers? is there any special math or trick?
i've been using 0 different kinds of interpolation between samples ... sample&hold, linear and cubic ... but one thing is the interpolation, the more complex problem is to find parameter values that give a decent behaviour ...
cheers ... tim
