Superbooth 23: UDO Audio Super Gemini, poly binaural hybrid synth with poly AT, first look

Superbooth 23: UDO Audio Super Gemini gives you almost double the voice power of the Super 6 poly binaural hybrid synth with poly AT and more.

George Hearn is a British Synthesizer developer. Among other things, he has developed the Modal 008. A flagship of an analog poly Synthesizer. Then he went his own way with his own company UDO Audio where he developed the Super 6. A binaural hybrid polyphonic synthesizer that combines analog and FPGA-based digital synthesis in an impressive form.

At Superbooth 23, the journey of the likable developer will continue. With the Super Gemini comes the next “Super” synth. With more voices, more hands-on control, and a polyphonic aftertouch keyboard.

I’m currently at the airport and didn’t have time to rewrite the press release. But I will try to find out more about the synth on SB and if they are more information, I will add them.

Press Release

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 bend your performances on a synth with unparalleled sonic possibilities.

Stacked with up to 20 voices of polyphony, the 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.

Digital Oscillators Meets Analog Filters

Spectrally rich digital hardware oscillators of unique construction, decorated with a plethora of 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. The result is a core- sound that is rich, evolving, engaging and addictive.

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.

Key Features

  • duality in control – dual synth control levels
  • 20 hybrid voices
  • state-of-the-art FPGA digital architecture
  • classic analog meets modern technology in a powerful, flexible, and reliable instrument
  • made entirely from aluminum and steel
  • 61-note semi-weighted keyboard with polyphonic aftertouch
  • true-stereo signal patch with 20 voices to form 10 super voices
  • left and right channels can be assigned a complete Synthesizer voice

First Impression

An excellent next step for the Super Synthesizer series I’m very pleased that they have decided on a polyphony aftertouch keybed because this is fits perfectly with the highly expressive and hands-on engine. And if you know George Hearn’s performances, you know that the Super 6 would also match with a polyphonic aftertouch keybed. I am looking forward to hearing more demos of it.

UDO Audio Super Gemini availability and price TBA. UDO will be at Superbooth, and you can visit them at booth B005

  1. And still no screen for simple patch management. Yet you want the user to attach an ipad to do so?

    • You can do everything without a screen, this is intentional, ipad is not needed.
      If you looking for screen there are many other synths to choose from, this synth is about performance, lala 🙂

      • I think you are missing the point, then again from your other comments on this site, you are missing much in life.

  2. I asked them at SB about polyphony, and the answer was 5 with dual layers and binaural.
