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

How complex do you wish to get with this module and the resulting sound file??

Something as simple as having each generated pixel represent a single tone, similar to how colors are chosen from a MAP file??  Or the simultaneous combination of notes in a chord to produce a harmony??

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.

truth, the whole truth, and nothing but the truth!

interesting results and discussion, i've been thinking of ways to do fractal "music" too; i think "sound" is a more appropriate term, since the chaos of fractals might not gel well with the harmonies one expects in (traditional) musical composition. then again, most of what i listen to these days can be safely classified as static or noise Wink

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 ...
