SGR1806-20 by Knob Technology - Analog Percussion synthesizer

The SGR1806-20 is an analog synthesizer module designed for percussion sounds, lead/bass voices, and various noise generation. The module consists of two primary voice blocks:

1. Voice Block “V”:

- Features three unsynchronized triangle wave generators with single pitch control (1V/Oct) and internal EG.

- Generators 1 and 3 include the Spread function for altering frequencies relative to the second generator.

- Frequency modulation (FM) capability with a routing of 1osc -> 2osc -> 3osc -> 1osc.

- Feedback option with manual control influences the summing stage.

2. Voice Block “N”:

- Incorporates three noise generators for various noise textures, controlled manually and via CV.

Voice signals from both blocks are mixed using voltage control (V<MIX>N), offering manual and EG-based manipulation.

The module includes a 4-stage voltage-controlled Wavefolder for shaping and enriching signals, along with a Distortion/VC Mixer (DIST) node that allows parallel control over distortion and mixing parameters.

A voltage-controlled amplifier (VCA) facilitates amplitude modulation, while an EG D Envelope Generator generates control signals based on trigger input, with routing options to various module nodes.

With its versatile functionality, the SGR1806-20 module offers a range of sound design possibilities, from percussion synthesis to complex waveform manipulation.
