I would love to integrate a fractal music modul in my fractal app. ARe there any resources about how to write such a thing?

I noticed in the thread title there was the word MIDI
Please dont use midi, fractal waveforms or harmonics are much more intresting.
Using MIDI to create fractal sounds is like using ms paint to create fractal imagery.

Iv'e tried using a 1 dimentional strage attractor to create a waveform

w = value of the waveform
c1 = a constant
c2 = another constant

repeat this lots of times (w = sin((w + c1) * c2))

It can sounds like someone screaming or like a bird being squashed or like an approcing train but usally eather silence or fuzz.
It all depends on the values of c1 and c2, nothing verry plesent sounding yet.

I would like to hear what cellular automata sound like such as spenski triangle or starwars (Its an MCell one) where the up\down position represented freqency and the left\right time.

Yes, it should be something like 'fractal generated modularity' or something like that. I just think of Amiga's Mindwalker (http://www.blachford.info/computer/walker/Bill_Williams-Mindwalker.mp3). Which has a very strange and long evolving sound pattern ...
