RasterFX

RasterFX is a modular multi-effects processor made to be played. Build a chain, add modulation, then morph the whole thing with one finger. The XY pad has a whole effect chain in each corner. Knobs blend fine, but a switch can't be 37% Tape, so modes and routing flip to whichever corner you're closest to.

One of the mod sources is a 1963 toy model of air convection: Edward Lorenz's three little equations that never quite repeat. Run them slowly and you get an LFO that wanders like a hand on a knob. The Chaos knob is ρ, and 28, the textbook value, is the default.

The look borrows from print. Every effect has its own halftone screen, Filter and Drive in dots, Delay in lines, Reverb in random speckle, and the angle belongs to the effect, not the slot, so Delay looks like Delay wherever you put it. None of them sit at 0° or 90°. Turning screens off each other is an old print habit. I just borrowed it.

And the bit crusher sits outside the 4x oversampler on purpose. Inside it, the anti-alias filter sands the stairs smooth and most of the crunch goes with it.
