UDO Super 6 Desktop Synthesizer White

Binaural Analog-Hybrid Synthesis in a Compact Desktop Format

The UDO Super 6 Desktop brings the acclaimed 12-voice binaural sound engine of the Super 6 keyboard into a compact, all-metal chassis built for studio and stage integration. A marriage of FPGA digital hardware oscillators and voltage-controlled analog circuitry, this synthesizer reimagines the Super 6 architecture for sound designers who want immediate, hands-on control without menu diving. The binaural analog signal path assigns each ear its own complete synthesizer voice, transforming stereo headphones and monitor setups into a three-dimensional soundstage. With 128 rewritable patches and MPE compatibility, this desktop unit is a flexible centerpiece for any rig.

What Sets the Super 6 Desktop Apart

Two rare architectural choices define this instrument's character. The 7-core super-wave main oscillator pairs a centroid oscillator with six sister voices that can be independently de-phased across the stereo field, producing lush, animated textures from a single oscillator source. Equally distinctive is the binaural analog signal path: in binaural mode, the 12 voices are twinned into 6 stereo "super voices," with amplitude, filter, and oscillator parameters independently controllable for the left and right channels — a spatial imaging capability that ranges from subtle width to extreme 3D movement.

Oscillator Architecture — FPGA-Powered Super-Wave Engine

Built around ultra-precise FPGA digital oscillators sampled at 50 MHz, the oscillator section provides alias-free sound generation with the flexibility of digital control and the warmth of downstream analog processing. The super-wave structure allows for stereo detuning and phase offset at the source, opening up sound-design possibilities unavailable in conventional analog synths.

• Oscillator 1: 7-core FPGA super-wave (centroid + 6 sister oscillators) at 50 MHz — Sine, Saw, Square, Triangle, Noise plus 16 user-loadable waveforms (.ws6, 4096-point, 16-bit)
• Oscillator 2: Algorithmic FPGA oscillator at 50 MHz — Hard Sync, LFO mode, Sub Oscillator, PWM, and DDS 2 → DDS 1 cross-modulation for FM
• Mixer: Adjustable mix level with X-Fade mode — splits the keyboard for crossfading between oscillators or audio input

Analog Signal Path — Filter, Amplifier, and Effects

The analog signal path gives every patch the warmth, bite, and self-oscillation character that defines classic analog synthesis. The 4-pole low-pass filter is built around the SSI2144 chip, providing self-oscillation, keyboard tracking, and two levels of analog overdrive for everything from clean subtractive tones to aggressive, resonant leads.

• Low-Pass Filter: 4-pole 24 dB/oct SSI2144, self-resonant — with selectable keyboard tracking, autotune, and modulation from ENV 1, ENV 2, LFO 1, and DDS 2
• High-Pass Filter: 1-pole 6 dB/oct — fixed or linked to the low-pass for bandpass operation
• Effects: Dual stereo 24-bit / 192 kHz chorus and delay — chorus inspired by classic Roland three-mode designs, delay syncable and modulatable

Modulation, Sequencing, and Performance Controls

Every front-panel control can be targeted for modulation simultaneously, with LED feedback showing depth and routing in real time. The modulation matrix supports 20x audio-rate computation, while the multi-function LFOs and invertible envelopes provide detailed control over pitch, filter, and amplitude. The sequencer and arpeggiator are MIDI-syncable, making this desktop unit a flexible centerpiece for both studio and stage.

• LFOs: LFO 1 range 0.05 Hz – 20 kHz with stereo phase offset — reset, one-shot, and free-running modes, syncable to external clock
• Sequencer: 64-step with note, rest, slide, accent, and length tracks — 16 rewritable sequences, MIDI-syncable
• Arpeggiator: Multi-mode with Smart Hold — MIDI-syncable, ideal for live performance
• Patch Memory: 128 rewritable slots (64 factory + 64 user) — menu-free front-panel interface

Who This Synthesizer Is Built For

The Super 6 Desktop is the right choice for sound designers, electronic producers, and performing musicians who need a compact polysynth with deep stereo imaging and immediate hands-on control. Its binaural architecture makes it especially compelling for headphone-based production, film and TV scoring, and immersive electronic music, where conventional stereo panning falls short of the spatial depth this instrument delivers. Studio producers will appreciate the menu-free interface, MPE compatibility, and 128 patch slots for fast recall. Live performers benefit from the rugged all-metal chassis, VESA mount compliance, optional 7U rack ears, and flip-up feet that adapt the unit to any rig configuration.

UDO Audio — A Boutique Synthesizer Maker with a Clear Vision

UDO Audio is a UK-based boutique synthesizer company whose inaugural production instrument, the Super 6, was the result of many years of development. The company's mission has been to harmonize archetypal electronic instrument design with modern synthesis technologies that excel at generating spatially dynamic sonic results. The Super 6 Desktop represents the culmination of that vision in a compact, ergonomic package — built with precision engineering, premium materials, and a no-compromise approach to sound character and build quality.
