Metalizer

Initially I designed this circuit back in june 2010 for the commercial project I was involved in with the Arturia company. Now it is one of most characteristic feature of the Arturia's MiniBrute and MicroBrute monosynths.

This circuit is basically a wavefolder that makes it possible to generate very complex harsh metallic although stiil harmonic sounds. The principle is to submit the initial signal through a series of non-linear circuits which break and fold back the signal into a very complex waveshape. Yet the signal keeps it's fundamental and remains stationary.

To give life to this the circuit incorporates an exponential VCA to control the signal input level. This control gives rise to a continuous palette of sounds. The basic non linear folding cells are inspired by Ken Stone's Simple Wave folder circuit .

Basically, the most interesting results are obtained by feeding the module with a triangular wave or a sinewave.
