NEW LEVEL

The Super Gemini is a 20-voice polyphonic, bi-timbral analog-hybrid powerhouse. Employing an unprecedented dual-layer design, the Super Gemini gifts you with immediate comprehensive control over both timbral layers — allowing you to tweak, mold and transform your performances on a synth with unparalleled sonic possibilities.

Stacked with up to 20 voices of polyphony, each performance is an entire spectrum of sonic opportunity in which voices and timbral layers can be split, dualled, sequenced all at the touch of a single control. Unique spectrally rich digital hardware oscillators, decorated with expansive tonal features such as wave morphing, cross & ring modulation, bi-directional sync and more, all feed into an all-analog signal path inspired by the classic vintage instruments of our past.

Matching sonic innovation with tactility, the Super Gemini is equipped with a 61-note semi-weighted keybed with polyphonic aftertouch, in addition to a custom engineered ribbon sensor for individual note articulation and a gestural way to explore your sound. With 256 performance and patch slots, 32 interchangeable waveforms and 16 sequences, you can safely store and edit your sounds without concern.

As the second synth in the ‘Super’ series, the Gemini represents a quantum leap in UDO’s technology – building on the acclaimed rich sound pioneered by George Hearn and the Super 6. Adopting a true-stereo Binaural signal path with dual FPGAs and twin effects processors, Gemini will take you on an adventure of spectral dynamics, of glittering frequency and shattering subharmonics, of comfort and discord, expectations and surprises.

Inspired By The Classics,
Built For Today

Super Gemini fuses a state-of-the-art FPGA digital architecture with archetypal voltage-controlled synthesizer technology. This harmonious marriage of old and new encompasses all that is great from the era of classic analog polyphonic synthesizers, yet in an unparalleled form factor which is immensely powerful, flexible, and reliable.

What is Binaural?

Binaural refers to the twin synthesizer signal paths. In Binaural mode, each channel (ear) has a complete synthesizer voice. You can detune and de-phase the left and right oscillators, amplitude and filter (and indeed other parameters) relative to each-other. Ranging from subtle to extreme, this unique feature allows for experimenting with the 'width' of the sound and creates an improved sense of 3D positioning. It has in this sense one “super voices” for every two “conventional” voices.

‘traditional’ voice architecture
binaural (super 6) voice architecture
FPGA digital oscillators

The Super Series instruments leverage the power of ultra-precision FPGA digital oscillators for a direct and alias-free sound source. This cutting-edge technology combined with an archetypal analog signal path to the outputs provides a rich and flexible sound canvas that can be sculpted for warm basses, expansive pads, and sparkling leads.
