A Chaotic LFO

This simple patch implements the "logistic equation", which is a simple way to generate non-repeating, chaotic patterns.

Adjust the knob labeled "3 < k < 4" to vary the pattern from ordered to random.

Thanks much for this patch. I have not tried implementing logistic EQ on the G2, but I did some work with it in reaktor. you might find the attatched audio clip of interest:

gxaos1.mp3

Description:

recording of reaktor noodle: 4 logistic eq's, each with different constants and their own sampler. The same sample is being triggered in all 4, two strums of a dom7 chord on an acoustic guitar. The eq's are also set up to cross modulate the pitches, st

Thanks, fellers.

I figured out how to fix the annoying reset behavior, and it even requires fewer modules. The new version is up.

This is great.
The output also makes some interesting, organic tones if clocked by an oscD.

Thanks for posting

Zynth, your track sounds fab. Cool

Could you post the equation here, or a pointer to a site that explains it?

How do you know that k should be between 3 and 4?
Trial and error, or is it a recommended value?
Are there any constraints on x[0] besides not equal to 0?

Zynth, now that you can see how to make this chaos patch using the G2, why not try a version of the Reaktor patch and let us see how it's done? This stuff if facinating.
