VCOb Eurorack Oscillator Module

Bubblesound VCOb: Precision Analog Synthesis

The VCOb is a boutique triangle-core oscillator designed for sonic purity and versatile modulation. The core of this module is engineered to provide highly symmetrical waveforms, resulting in a sine wave with incredibly low harmonic distortion—perfect for clean sub-basses or carrier signals in FM patches. With dedicated outputs for all primary waveforms and high-resolution tracking, the VCOb functions as a dependable primary voice.Its ability to handle exponential and linear FM simultaneously allows for deep, evolving timbres that range from musical vibrato to metallic percussion.
