baseOsc Module
Add on VCV Library

Overview

The baseOsc is a versatile oscillator for VCV Rack, designed to serve as the core of your sound design setup.

Drawing on robust code from the Mutable Instruments’ Braids oscillator, it offers a range of audio output shapes including triangle, sawtooth, pulse (with PWM), sine, and square sub-oscillator.

With its wavetable capability, users can smoothly interpolate between samples and cycles, and control the wavetable index for dynamic sounds.

The baseOsc features unique noise options, including pitched noise and digital clocked noise with modifiable sample cycle length and quantization.

Pitch controls allow for precise adjustments via coarse and fine tuning, octave shifts, and frequency modulation.

FM CV input can be atttenuverted, and the reponse can be toggled between linear and exponential.

When in LFO mode, the module’s LED indicators display output polarity, enhancing visual feedback.

The built-in quantizer supports 19 scales and allows you to choose the root note, with LEDs indicating the current scale + root configuration.

A global bit reduction parameter for oscillator output can be set from 1-bit to 16-bit resolution.

The baseOsc is ready to be an essential building block in your patches for shaping both musical and experimental sounds.
