The Harvestman Hertz Donut mk2

Inspired by the Buchla 258, The Harvestman Hertz Donut mk ][ is a powerful digital dual oscillator with dynamic-depth-thru-zero-frequency modulation. The module features a 16-bit digital audio system and an ergonomic interface that affords effortless access to a variety of operational modes. 

Each of the module’s oscillators boasts an extremely wide frequency range and can function independently or in sync. An expertly-designed internal bus offers powerful modulation control over each oscillator’s frequency, wave folder drive, tracking phase, and amplitude. Proficient digital controls allow for quick alteration of the modulation destination without the use of patch cables. Most of the module’s CV inputs feature attenuverters, affording bi-polar modulation of all primary parameters. 

Additionally, the module features a proficient triple-mode tracking controller that forces the modulating oscillator to conform to the primary’s frequency. There’s also an internal audio-rate modulation bus that allows for phase modulation techniques. Each of the tracking modes can be modulated together for a plethora of grotesque and singular sounds unavailable from other oscillators.
