The Bubblesound VCOb is a wide-range analog triangle-core voltage-controlled oscillator designed for both audio synthesis and low-frequency modulation. Its extended frequency range allows operation from slow LFO-style movement up into the upper limits of human hearing, making it a flexible sound source for a variety of modular systems.
The oscillator maintains stable 1V/oct tracking over approximately 46 octaves, providing reliable pitch control for melodic and harmonic applications. Its triangle-core design delivers smooth, musical waveforms and classic analog character.
Multiple waveform outputs are available, including triangle, saw, sine, and pulse. The pulse waveform features manual width control as well as CV modulation with full 0100% range, enabling rich PWM effects. A dedicated FM input with attenuation and a selectable linear or exponential response allows for expressive frequency modulation, from subtle timbral movement to complex modulation textures.
