UDO OMN-1 Synth Control Expansion Module for DMNO ON

DMNO ON is the full-featured 8-voice, 2-part multi-timbral DMNO synthesizer in a compact desktop format. Built around two independent analog-hybrid synth engines, it retains DMNO’s highly flexible signal architecture, with each engine featuring our new Dynamic Multi-Core Stereo VCF. Eight creative Play Modes unlock dynamic interactions between the two timbres at the touch of a single control, while its flexible analog and digital audio connectivity make it a truly expansive and immediate sound design sandbox.

A new approach to analog. DMNO merges UDO’s championed hybrid sound with a cutting-edge, playful, and performative control architecture. Eight-voice polyphony, dual hybrid binaural synth-engines, and the entirely new per-voice analog Dynamic Multi-Core Stereo Filter system deliver a deep sonic palette, from extreme, overdriven textural scenes to rich, organic analog warmth.

The ON system introduces expandable control. The base unit features a streamlined single control-set while retaining the full 8 voice bi-timbral synthesis engine. Add an ONM-1 Synth Control to recreate the dual DMNO layout, and/or an ONM-2 Effects Control for hands-on playability of the onboard effects engines. With a suite of ONM units planned, the ON ecosystem will grow to allow players to build and shape the instrument around their own workflow.

At the heart of DMNO is the Play Modes system. Instantly reconfigure the internal architecture at the touch of a single control with eight carefully curated modes that redefine how the two timbres interact, with traditional splits and layers sitting alongside novel, creative, and unexpected configurations. Complementing this versatility is a suite of flexible connectivity options, including an analog audio input with preamplifier, gate generator, and envelope follower, CV/Gate connections for the analog realm, and a 24-bit USB class-compliant digital audio interface.

While the core UDO sound stands confidently on its own, DMNO also includes a high-resolution digital effects engine. Delay, reverb, EQ, distortion, chorus; each effect has been meticulously crafted, capable of subtle to extreme tones that are always musical, never abrasive (unless you want them to be). All of this is controlled via the best screen we could find: a beautifully sharp, yet somehow warm and organic, high-contrast electroluminescent glass vacuum fluorescent display (VFD).

Stack Up. Knock Down.
The two fully-featured independent synthesizers (DMNO 1 & 2) take centre stage, each representing a complete timbral layer with its own oscillators, filters, modulation, and effects. Both DMNOs are driven by two ultra-high sample rate, high resolution FPGA-powered digital oscillators, each routed through an exceptionally powerful and versatile stereo analog filter (read on for more on the filters).

Oscillator 1

• FPGA-based super-waveform oscillator core featuring a centroid oscillator and six ‘sister’ oscillators that can be dynamically de-phased in the stereo field to produce wide and thick single-oscillator sounds in ‘super mode’.
• Wave shapes: sine, sawtooth, square, triangle, pulse and up to 6 alternative complex waveforms that can be user-updated via onboard display.
• Noise generator.
• Tune control with fine adjust.
• Oscillator sync with options for syncing 2-1 or 1-2.

Oscillator 2

• FPGA-based super-waveform oscillator core featuring a centroid oscillator and six ‘sister’ oscillators that can be dynamically de-phased in the stereo field to produce wide and thick single-oscillator sounds in ‘super mode’.
