Kim Bjørn brought an interesting small setup along to the Danskmodular meet-up last Saturday. It included the Mi.1e, a bluetooth MIDI to CV adapter that connects wirelessly to an iPad, enabling it to operate, via its own iOS app, as a sequencer, LFO, MIDI to CV interface and more.
At the Danskmodular meet-up in Copenhagen last week Konstantine got into explaining how one might approach creating a chaos patch on an analogue modular system without using a random/chaos module.
He demonstrated how the logistic equation k*x*(1-x) might be reformulated as k*(x-x^2) so as to make it easier to patch. (Some source reading on the equation can be found here.)
I had a go at putting it together in Audulus, both using the expression node as well as simply using the multiplication and addition nodes.
It turns out to be a simple way of achieving something similar to the kind of chaos spectrum Rob Hordijk achieves with his Rungler. The logistic equation outputs a constant value when k is smaller than 3, followed by a period of doubling with a second bifurcation at 3.5, chaos shortly after 3.577, and 3-step period around 3.83.
