The input is multiplied by Drive (in dB), passed through the chosen shaper, filtered by Tone, blended with the dry signal by Mix and trimmed by Output. The shapers are Soft clip, Hard clip, Asymmetric and Wavefold. A DC blocker removes any constant offset that Bias or the Asymmetric shaper creates. Quality sets filtered oversampling to reduce aliasing; every setting has the same 12-sample processing latency, aligned before the dry and wet signals are blended.
Use it to warm a clean tone, thicken bass, or add edge to a synth. Follow it with a Low-pass filter or its own Tone control to tame brightness, and with a Limiter if the level gets hot.
An offset into the shaper, from -0.9 to 0.9. It changes which half of the wave is shaped harder, adding even harmonics. A DC blocker removes the offset afterwards.
Each help patch is an ordinary Toy that teaches one idea. The diagram shows the Patch; the preview shows its Frame. Open it in TuneToys to play and edit it.
