Nonlinear oscillators, chaos and FM

Here's some examples of sound synthesis with nonlinear ordinary differential equations and iterated maps.

I could post source code (C++) for the FM systems if someone is interested, though it might take some time to prepare.

Re: Patch to visuals? Add visuals to audio?

When I started thinking about my first animation some 20 years ago, I had seen a few videos that tried to knit audio and visuals together by some kind of signal visualisation, or maybe using the same data to control processes in both domains. I thought, that's not what I want to do! Neither full mic...

Lokomotiv Konkret had their intense moments (most of the time). Just received a batch of CDs from Nurnichnur, definitely improvised, maybe free jazz, often with electronics and mostly not very brutal, but worth a second and third listening.

Re: Book recommendations on synthesis techniques / sound design

I'll give a list of books for computer music, some of which present sound design ideas in such a general way that they can be easily transferred to an all analog modular.

Re: Deep Learning and modular synths

Re: Composing with a modular

Unlike instrumental music, there is really no repertoir for modular, for quite obvious reasons. So compositions for modular are specific, unique to the particular combination of modules at one's disposal. I also suspect it is much more common to set up a patch once and document it with a recording r...

Re: Counterpoint with modular

Counterpoint is a nontrivial matter, and as the replies have shown, this is only more so in a modular context. In my case, I'm not really interested in writing serious formal pieces, what attracted me was rather the possibility to easily make a large number of counterpoint type variations on a simpl...

Re: FM synthesis - Essential non-pop records

Magnus Lindberg's Ur and Jonathan Harvey's Valley of Aosta use the DX7 in otherwise acoustic chamber music settings. I think it was quite common in the late 80's, but can't think of any other examples at the moment.

Re: The esoteric out-to-out patching

Something much safer is taking an output signal from an input. That's possible at least with the metasonix R-54, and maybe with some other modules.

Cascading some VCAs with in additional stuff (audio rate or lower frequency) into the CV ins would give the OP the sort of thing they were asking about, right?
Exactly, you would have to use cascaded VCAs.

I forgot to mention there is a paper about feedback AM.

Re: AM algorithms?

AM is much simpler than FM, being just a multiplication a(t)*x(t) where a(t) is always positive or zero. You can make tremolo effects at slow rates. AM introduces side bands around the carrier (which will remain, in contrast to ring modulation where it is suppressed). The side bands can cause beatin...

Re: All Eurorack Chaos modules

I don't think that a conservative analog circuit can exist though - heat dissipation is a thing after all, except if you had a superconducting module, which would presumably tax your power supply too much :hmm: Interesting, I didn't know that. Would that also rule out a self-oscillating filter as b...

Re: All Eurorack Chaos modules

I don't think I will classify modules by type of chaos. Logistic map forms a discrete system. That means you only get one output. Modules based on the Lorenz system, continuous, gives you 2 (or more) out-signals (X, Y, Z in a graph). Correct me if I'm wrong. I studied Human geography... Fair enough...

Re: All Eurorack Chaos modules

Here's a chaos module that most may not recognize as such: the Pulp Logic V-Noise (video noise.) These types of noise generators use shift registers with feedback to create long, noncorrelated, but ultimately deterministic binary patterns that mimic randomness. That's chaos, pure and simple.

Looks like a promising idea.

Re: two soundcloud albums

Brilliant baroque interpretations!
They also put the more modest chaos clips into perspective. I don't know if they are intended as module demos or studies, but hearing them in a collection it is striking how their musical syntax differs from that of any other music.

Something-else. I tried to use my A-156 quantizer in a feedback loop. I did not work the way I hoped :-( Although I don't know what else was in that loop, let me guess what could have happened. For a feedback loop to start oscillating periodically or chaotically there must be a bit of amplification...
