I was tinkering about the way the crease function would be unstable if it fed back on itself, and I figured out a very simple noise patch! It sounds a lot like Dunst I think.
crease out > offset in
left out > crease in
right out > audio out
What amazes me is how controllable it is given it’s simplicity. Survey controls noise texture. Fully counter-clockwise, you get silence. Just below 9:00, there is a sweet spot where you can get white noise, which fades again to silence. Between 9:00 and 3:00, you get vinyl-craclke like noise made from sharp transients which gets denser as you get closer to 12:00. Symmetrically, you get white noise just past 3:00, and silence fully clockwise. There is some DC offset at the extremes, which is not ideal for FM duties unless you AC-couple it first. It’s great when applied to Mangrove’s barrel as it nears the edge of two undertones.
Even cooler: you can get it in stereo if you happen to have a splitter or some stackables. The crackles you get seem to be completely decorrelated, as if they came from distinct sources.
crease out > offset in
left out > splitter
splitter > crease in
splitter > audio out
right out > audio out
Even cooler! Patching in an audio signal to either left or right in will allow you to go from a completely clean signal to a noisy, distorted, and utterly destroyed signal, all while creating a stereo image.
Stereo input won’t work though, as this is based on feedback in the crease circuit, which needs an offset to be in a stable state. Simply breaking the offset normalization with a dummy cable on the other channel brings in full-power crackles. The crossfader does many things at once: it provides the clean signal when the distortion is dialled back through survey and provides a voltage far from zero volts so that the crease circuit is stable, and as the survey knob is turned, the offset gets closer to zero and more of the signal goes through the crease circuit.
