YuSynth Metalizer

Introduction

A bare double sided PCB (no need for the wire jumper links shown on the PCB layout) for the Yusynth Metalizer synth module. These PCBs are manufactured by Soundtronics with a percentage of the sale going to the creator of the YuSynth - Yves Usson. These are early days for the YuSynth Modular Synth at Soundtronics, our plan is to stock PCBs for all of the projects as well as components, kits and front panels. This is going to take time but will eventually be as comprehensive as our MFOS range.

No components are included with the PCB but check out our Synth Components section where you should find what you need. We do suggest visiting the YuSynth Metalizer project page for detailed information including Yves panel layouts but a summary is shown below.

Erratum

Sorry but there is a small error on the PCB silk screen associated with the signal input, the GND and IN legends are swapped over. The input should go to the pad nearest to R3.

Description

Initially Yves designed this circuit back in june 2010 for the commercial project he 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.

The PCB can accept a choice of three types of power connector, it can be either a Synthesizers.com 6 pins MTA connector, a MOTM 4 pins MTA96 connector or a 10-pin Eurorack connector.

Parts List

The parts list below is direct from the YuSynth website.

The parts list excludes knobs although we have standardised on the Cliff KM20B but it does include 1/4" jack sockets. All parts are available individually (use the part number in the search box above) or as a components kit that excludes sockets and knobs.
