(Description for Generator)

Dual Oscillator FM Monster

A dual oscillator built around two triangle core, wide range, periodic waveform generators. As a multipurpose signal generator, it can provide the basis of a wide range of complex sounds ideal for tuned percussion/noise, abrasive amplitude, frequency and timbral modulation. Tones, drones, textures, and drums to atonal, nintendo zipper/fart noises. This module was made for FM madness.

(Description for Genxpander)

Waveshaper / Wavemangler Expander Module for the Generator

The GenXpander is an expander module for the Generator. It adds standard waveform outuputs, internal FM waveform selection, extensive waveshaping capabilities to the Generator module.

The GenXpander has 4 separate sections.

Waveshaper

The waveshaper circuit uses a triangle wave square wave from or both of the oscillators on the Generator module to create a saw wave a pulse wave. Attenuated CV of the pulsewidth saw shape is available. A switch for the triangle wave a switch for the square wave determine which oscillator the seed waveforms are taken from.

Selecting the same oscillator for both triangle square will provide a clean saw wave. Selecting different oscillators for the triangle square waves will provide a interesting modulating, saw-triangle-square type waveform.

FM Wave Switch

Determins the waveform by oscillator 1 (GEN1) to internally modulate oscillator 2 (GEN2). The Generator ships with the internal FM set to the variable waveform. The switch allows the frequency modulation waveform to be changed to a triangle wave.

Standard Waveform Outputs

Separate triangle square wave outputs for both oscillator 1 (GEN1) oscillator 2 (GEN2)

BAD Outputs

An odd/even harmonic detector, frequency mixer & waveshaper. It inverts the polarity of the triangle waves based on the frequency relationship between oscillator 1 (GEN1) oscillator 2 (GEN2).

OE Output:
Regular polarity oscillator 1 triangle if the difference between oscillator 1 (GEN1) oscillator 2 (GEN2) is an even number. Inverted polarity oscillator 1 triangle if the differance between oscillator 1 (GEN1) oscillator 2 (GEN2) is an odd number.

DIF output:
Polarity of oscillator 2 triangle is changed at a frequency equal to the differance between oscillator 1 (GEN1) oscillator 2 (GEN2). If oscillator 1 (GEN1) oscillator 2 (GEN2) are the exact same frequency then the DIF output is the same as the oscillator 2 triangle output.
