"A wavefolder is a non-linear waveshaping circuit that allows to create rich harmonic waveforms. Its a distortion circuit that folds back the signal when it reaches a cerTain level. Wavefolding can be seen as the opposite of filtering. Instead removing harmonic content to the incoming signal, a wavefolder adds harmonics to the original signal creating a more complex waveform. For this reason wavefolders work best with waveforms with low harmonic content like sine waves or triangle waves.
Wavefolders together with Lopassgates are one of the main building blocks of the West Coast Synthesis.
The C113 West Coast Timbre features two different wavefolder circuits based on two classic west coast modular synths Buchla and Serge.
The C113 West Coast Timbre main characteristics are :
Two selectable wavefolder circuits.
Manually and CV controlled folding amount
Manually and CV controlled symmetry for non symmetrical folding.
Two audio inputs, one of them attenuated.
Two audio outputs, one of them controlled by a VCA
Thanks to the included VCA, a full featured voice can be created with a minimal amount of modules like a VCO, an envelope and the C113."
