UDO Super Gemini Questions

Is one layer still 10 super voices? or 5 on each layer?

Turn binaural mode off and you get 10 voices on each layer. for sure…

Here’s my interesting question, is the binaural mode per layer or only for the whole synth? I could see wanting to do a mono lead or bassline with a wider pad sound.

I think it would be nice if voice allocation was dynamic. So if you‘d play a mono bass line on the left part you would have up to nine voices for the right part etc.

Binaural can be switched on and off independently so you can have:



So you can always have up to 10 voices in any one layer regardless of the other layer settings.

The hardware is true-dual (Gemini!?) so there are two pairs of outputs (plus mix) two independent fx processors etc. which means the voices cannot be split dynamically, however choosing 20 analog voices means there’s generally enough for most uses most of the time.


Why the Gemini is not a real twin S6 → 2 x 6/12 voices = 12/24 voices?

Is it due to the morphing feature (which has to mix between 2 different waveforms online)?
If yes, could this morphing feature be introduced to the S6 by dropping voices?

Some more questions:

  • LFO2: does the LFO2 implementation in Super Gemini support higher frequencies comppared to S6? If yes, will this be implemented to S6 in a firmware update?

  • LFO1 upper/bottom layer: are they related to each other by common clock? If no, how can they be synchronized? I assume, a constant phase relation between both can be managed by the phase slider, correct?

  • Is the Audio Input not available any more for Super Gemini?


LFO2 is broadly similar as Super 6 but does have different wave shapes. The frequency range is extended a bit because the aftertouch can increase its frequency and one doesn’t want to max it out. No plans to increase on S6 right now.

LFO1 is synchronous upper/lower when in single mode. ARP/midi clock sync works the same way as s6.

Audio in is only on super 6 and desktop, not Gemini



is there any good material focusing on raw sound difference between S6 and Gemini? I know that George mentioned few details in one of Superbooth interviews, but I would like to know more.
I love the sound of my S6, but always missed the 5th octave and the second layer, so I have preordered Gemini at the second it was listed. Now I wonder if the sound difference is that noticeable that it would justify keeping both instruments or not…
