[osc~]1 modulates the frequency of [osc~]2 which modulates the frequency of [osc~]1 again and so on, you end up with chaotic oscillations that sound like this when you tweak them in certain ways:

(last track uses cheesetracker as well as Pd)

sounds like good

i wanna try this at home.

Here's an example patch. You have to use s~/r~ pairs to avoid DSP loop errors, which introduces a delay of the dsp-block-size.

hey it works well.

not sure about doing 3000000 millisecond line sweeps though. ha ha ha
