Wave Shaping
Distorting and Wave-Shaping
A few facts about distortion and waveshaping:
  • Difference between Waveshaping and Distortion: Distortion works with signal overload, shaping is controlled change of parameters.
  • Waveshapers and distorters add overtones. It's therefore sensible to use material w/o a lot of overtones, e.g. no square wave but sinus.
  • Waveshapers and distorters react to the amplitude of the signal. The louder the signal, the  higher the distortion. Below three ways to control a WaveWrapper.
  • Multiple wavewrapper multiply the effect.
  • The effect of waveshaping is best used with modulation.

Controlling shapers
Three common ways to control the sound of two oscillators with a waveshaper modul are
a) just by the amplitude of the sound
b) an envelope
c) let one oscillator control the modulation.

Tone Source Shaper

This is an idea from a module on Grant Richter Synth DIY pages. It is a wave shaper that addresses tone in a musical way. There are two controls that determine the harmonic content. The first fades from even only to odd only harmonics, with a saw like tone in the middle. The second control fades between the source sine and the shaper output to vary the amount of harmonics.

You can modulate both controls.
