This segment from Bitwig's official Grid tutorial walks through four distinct waveshaper-style modules side by side, showing how each one remaps amplitude differently to produce its own character.
Distortion applies a soft curve that pushes quieter signals upward, giving the result a warmer, more natural feel. Bend lets you define that curve manually, flipping the behavior so only the loudest peaks break through for a metallic, chirpy texture, or pushing it the other way to treat most of the signal as increasingly loud.
Wavefolder takes a different approach by wrapping extreme amplitude values back around rather than clipping them, which introduces repeating cycles and a natural harmonic quality. Quantizer reduces amplitude resolution into discrete steps, creating a stepped, square-wave texture where silence appears more often as the step size grows.
All four modules stay within the zero-to-one signal range, so they work as pure remapping tools. Seeing them compared back to back makes the underlying logic of each one much easier to carry into your own signal chain.
