Waveshaping Synthesis is a type of distortion synthesis that can create dynamic spectra in a controlled way. In waveshaping, it is possible to change the spectrum with the amplitude of the sound. A simple example of this method is the clipping caused by overdriving an audio amplifier. These simple method creates an astonishing variety of sounds which are very unique and can't be reproduced by any other contemporary synth! microTERA gives you also a method of getting randomly generated sound patches in a way you never experienced before: roll the dice!
