Can Strange Attractors be clocked?

[Music Engineer]

As I read that I was actually thinking about calculating at the lowest acceptable resolution (high delta) and then interpolating/up sampling. Whereas the render would be at the highest resolution and then go down.

ah - OK - i actually used here "render" irrespective of the resolution/quality. i just meant it in the sense of "generate an output"

^To me, render implies the output is built and then used only after processing is complete, as opposed to outputting as you are processing. It's from my background in SCADA system design.

I think we are all clear now, though. Back to the topic.

I have been designing a synth called ChaoSynthOne where the oscillators are based on the chaos equations, along with some forced harmonic ones. I even registered the name but then got sidetracked by life. I'll get back to it and see where I got.

That sounds fun, you should really complete it! I'll never be able to take the example that far...

My needs are a lot less demanding - just a noise generator - with one parameter that I can fool around with in real-time.
Inanyway - the 'dt' trick does not work perceptually in this case - I missed one very stupidly obvious thing. I'm updating this thing @ samplerate and the solution to the system is not just an oscillator - but a lowpass filter as well - SR->48kHz it's -130dB at 8kHz(SR/6). Varying the c Parameter - slightly alters the frequency response of this lowpass effect. So if I were to simply upsample to where I'd get full spectra up to 20kHz - I'd think I'd lose some of its character, and I'd need a rather steep LP filter to control its bandwidth from scratch again. The main question still stands though - can it be clocked - like a LFO - i.e will this recursive solution hold or blow up

I haven't had a chance to look at it in a PC yet. I'll get back to you when I do but it won't be till next week.

For now, I would plot your results and do simple differential analysis to see how the solutions change with coefficients and samplerate. That will at least give you a ballpark to head for.

As for the synth, I will start it again but not for a couple of months. I had completely forgotten about it, but I had a feeling of deja vu when I read this threads. Cheers for that.

Oh, and if you are happy with the sound at a particular samplerate, then just fix it at that, or render to a sample, and interpolate for others. Don't worry about a full resample, it is noise after all.
