Product Description

The UDO 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 bend your performances on a synth with unparalleled sonic possibilities.

An Entire Spectrum of Sonic Opportunity

Stacked with up to 20 voices of polyphony, the UDO Audio Super Gemini boasts an immensely powerful sound engine where a performance isn't just a single sound, but 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. Spectrally rich digital hardware oscillators of unique construction, decorated with a plethora of expansive tonal features such as wave morphing, cross and ring modulation, bi-directional sync and more, all feed into an all-analogue signal path inspired by the classic vintage instruments of our past. The result is a core-sound that is rich, evolving, engaging and addictive.

Tactile 61-Note, Semi-Weighted Keybed

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, 64 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.

  • Duality in Control – Equipped with dual synth-control levels, the Super Gemini gifts you with comprehensive and immediate control over multiple timbral layers, calling out for you to tweak, mold, bend your performances in an unprecedented, real-time form.

  • The Power of Play – Boasting an enormous 20 analogue voice count, the Super Gemini equips the player with an uncompromisingly powerful sound engine, freeing your sound from physical limitations and empowering the player to explore the celebrated UDO sound to its absolute fullest.
  • 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 analogue polyphonic synthesizers, yet in an unparalleled form-factor which is immensely powerful, flexible, and reliable.
  • Premium Build Quality – Forged entirely from aluminium and steel, the Super Gemini is undeniably robust. Equipped with an array of superior quality mechanical controls, the Super Gemini is engineered for reliability and service. As a loyal workmate and companion, this instrument is designed to stand the test of time.
  • Expression – Featuring a custom-engineered ribbon controller and a 61-note semi-weighted keyboard with polyphonic aftertouch, the Super Gemini will enhance your musicianship from the first touch, teasing out new ways and gestures for you to explore and express your sound.
  • Binaural Synthesis – Employing a true-stereo signal path, the Super Gemini twins its 20 voices to form 10 "Super voices". As a result, the left and right channels and each ear are assigned a complete synthesizer voice. Not only does this allow for the warm analogue tone that UDO is championing, but it empowers you to create extremely dynamic spatial sounds!

The Super Gemini really adds something exceptional to the synthesizer world. So many synthesizers available focus on reissuing what was done 40 years ago, but this Super Gemini offers unique sounds and harmonics with a specific character. The construction is of very high quality and everything was thought out extremely well. Brilliant! The keyboard feels very smooth, and its polyphonic after-touch is very precise. All sliders and potentiometers feel like UDO sourced the best material available. To be picky, I wish they had included an onboard reverb but I can make it up with the delay, the binaural and a bit of DDS modulator detune.
