Description

Edit description

Step into a realm of sonic exploration with the Industrial Music Electronics Hertz Donut MkIII, a complex digital oscillator designed for adventurous sound artists. As a leading light in the modular synthesizer world, this Eurorack module offers a doorway to intricate digital synthesis and modulation possibilities. It features a programmable 4x3 modulation matrix that empowers you to craft sounds with unparalleled precision and depth.

With a primary oscillator modulated by two sine wave operators and an external audio input, the Hertz Donut MkIII delivers a rich tapestry of phase distortion synthesis and Thru-Zero-FM. Its modulable wave-folder and 8-octave range ensure that your sonic palette is as wide as your imagination. The module's modulation operators can be freely tuned or set in fixed frequency intervals, providing flexibility for both experimental and structured compositions.

The Hertz Donut MkIII is more than just a tool; it's a creative partner with features like preset morphing and CV control, allowing for dynamic performances and spontaneous sound design. The preset manager offers 8 memory locations, making it easy to recall your favorite soundscapes. Operating at a high-fidelity 96 kHz sampling rate, this module ensures clarity and depth in every note.
