On some other thread I spotted someone with an interesting sig:

Code:
     

      dx/dt = delta * (y - x)

      dy/dt = r * x - y - x * z

      dz/dt = x * y - b * z


Which turned out to be a Lorentz attractor thingy, more info about this can be found at :

http://www.enseeiht.fr/hmf/travaux/CD9899/travaux/optmfn/hi/99pa/hydinst/report03.htm

The attached patch is an implementation of this sig applied to some simple bleeps.

To start the process with a random seed the button on the red module must be clicked. When the pattern gets boring another click will start some other sequence. Diffent values can be set for the delta, ra nd b parameters, this is a bit critical - you might want to try to change the integration constants as well in the F(d/dt) modules.

And a Rossler thingy, from the same url I mentioned above.

This one uses :

Code:

      dx/dt = -y - z

      dy/dt = x + Ay

      dz/dt = B + xz - Cz


It's different, and harder to get interesting things out.

And a slightly more interesting example of the Lorentz patch.

I added some knob assignments for easier control for keyboard owners, the Rossler patch has the same knob assignments btw.

Ah there is the sig I meant, I somehow knew I'd get you into my strange attractor :-)

(delta, r, b) = ( 54, 43, 36) gives a very nice pattern, had it running for quite a while now. And meanwhile I've been looking for interesting four dimensinal sets of non linear differential equations having strange attractors - do you happen to have any references ?

Jan.

ps: a nice introduction I think, and very readable, is : http://amath.colorado.edu/faculty/jdm/faq.html

i used to develop flash sites with those equations, www.logotype.se, but the webserver is not online right now due to re-install... but i'll let ya know when its up again... would really like to use that patch/export sound... would be cool to have a realtime flash app, with sound (not realtime sound tho)

Please do eagarding letting me know, and please do regarding flash app & sound as well.

CanĀ“t flash output midi these days too? That would pave the way for a n.dimentional "noodlesequencer" with a "timeline" that would turn and twist over the schreen.

This is very very cool. Cool

I'm trying to catch up on posts after being away for 2.5 days. I'm going to come back to this. Thanks, Jan. I dig this.

Already thought you would like this Howard, but be warned it's not really easy to get nice things out - percussive might be the way go.

I didn't feel sure enought to post this to the snippets section - I mean the request you posted a while ago for chaos patches.

Anyway, hope you enjoyed your holiday :-)

Jan.

Basic Lorenz attractor

same like BlueHells algo but other patching ( self clock system )
