UDO Audio Super Gemini Polyphonic Hybrid Keyboard Synthesizer - White

The UDO Audio Super Gemini polyphonic hybrid keyboard synthesizer brings a new level of direct control and spatial depth to modern sound design. With 20 voices and a unique dual-layer structure, users can sequence, split and blend patches in real time across two distinct layers. The instrument features up to 20 voices of polyphony, built around digital oscillators with wave morphing, cross modulation and ring modulation—all routed through a classic analog signal path. A 61-note semi-weighted keybed with polyphonic aftertouch and a custom ribbon controller enables expressive playing for advanced synthesis, live performance and studio composition. For musicians who want immediate control over stereo imaging and modulation, this synth makes it possible to shape sounds on the fly and capture intricate details in a single take.

Dual-Layer Synth Control Enhances Real-Time Tweaking

The dual-layer design of this keyboard synthesizer lets users adjust two timbral layers at once, with split and stack functions available from the front panel. Dedicated buttons and controls for each layer make it easy to blend, sequence or tweak patches without navigating menus. This approach encourages creative experimentation, allowing players to transform performances and build complex textures in seconds. By shaping each layer in real time, users can develop richer, more dynamic sounds during live sets or recording sessions.

Binaural Stereo Signal Path Expands Spatial Imaging

With true binaural stereo routing, each of the synth’s 20 voices can be paired as 10 "super" stereo voices, assigning complete signal paths to left and right channels. Independent controls let users set detuning, de-phasing and filtering for each ear, building immersive 3D sound fields. This feature enables extreme or subtle stereo movement, improving spatial positioning and allowing for more dramatic effects than standard mono or simple panning setups. Players can create wide, evolving tones that cut through a mix or surround the listener with detail.

Advanced Oscillator Section Delivers Deep Sonic Sculpting

The FPGA-based digital oscillators provide classic analog waves and more than 60 user-definable shapes, with cross and ring modulation built in. The first oscillator supports "super mode," stacking several waveforms for thicker, more animated tones. The second oscillator brings sub-oscillator options, hard sync, and variable noise. An 8x8 modulation matrix per layer lets users patch envelopes, LFOs and direct controls with clear LED feedback. Three assignable LFOs per track and two stereo effects per layer make it possible to produce complex, evolving sounds that stay clear and punchy in a live mix or studio track.

Aluminum and Steel Build Supports Heavy Use

This synthesizer features a folded aluminum and steel chassis, with high-quality mechanical controls and a durable finish. The keybed is semi-weighted for comfort and precision, while the ribbon controller is engineered for responsive modulation. The front panel and rear connections use rugged jacks and buttons, supporting frequent setup and teardown for touring musicians. Its construction resists wear and tear, ensuring the synth stays reliable over years of studio or stage work.

UDO Audio Super Gemini Synthesizer Supports Creativity

Musicians and producers who need direct control, spatial imaging and flexible modulation find this synth lets them design and perform evolving textures with speed. The combination of dual-layer access and true stereo voicing results in performances that sound wide and detailed, supporting fast edits and creative risk-taking. These features help users move from inspiration to finished tracks with fewer barriers and more room for expressive detail.
