Hello and welcome to your new UDO synthesizer. What sits beneath your
ngersisaninstrumentcraftedinrecenttimesyethavingbenettedfrom
a long history of players and pioneers, of engineers and artists, technicians
and tinkerers over several generations.
There is a magic in synthesizers, a detail between the lines, in the space
between the traces of copper, and the complex interactions of code and
fabricationsofmetal.Ifwearelucky,wecanndourselvesinastateof
owasweplay,comfortablyputtingasidethechallengesofourinner
world and the wider world beyond, and fully focus on the unique joy of
whatwendourselvesengagedwith.Ifweareluckierstill,wecanshare
this moment with others. Yet, if you are one of those who have come to
own this synthesizer, you have probably already learned the healing and
restorative qualities of creativity as its own reward.
The creators of what you have before you understand the power of
play, and what you play now while not a simple instrument, works hard
to conceal its complexities and its secrets and presents you only with
straightforward expressive controls of a superior mechanical quality to
encourage you to seek and explore.
A journey into sound now awaits you and it is a journey with no wrong
turns, and no dead-ends. It is an adventure of spectral dynamics, of
glittering frequency and shattering subharmonics, of comfort and discord,
expectations and surprises, and accompanying you always will be your
loyal workmate and trusted companion, the UDO Super Gemini.
I hope you learn to love playing this instrument as much as I do, and when
youndthatmoment,thatsound,thatglimpseoffeelingoremotionthat
transcends your moment in time, then we have truly achieved something
good together.

OVERVIEW
The UDO Super Gemini is a 20-voice polyphonic, bi-timbral synthesizer
based on a hybrid of analog and digital technologies. By combining the
aesthetics and sonic character of vintage-era classics with state-of-the-art
synthesistechnology,itwasdesignedtobeexible,powerfuland,above
all, immediate – providing you with gorgeous sound times two!
DDS Oscillators
Direct Digital Synthesis is the signal generation method employed by both
oscillator cores of the Super Gemini. At its centre is a clock signal running
three orders of magnitude higher than typical audio sample rates. This
clock increments a counter through thousands of indices in your chosen
waveform, generating samples once every 20-billionths of a second and
interpolating between them.
Each numerically controlled oscillator then uses its own DAC, also running
at the same high sample rate, to convert the samples to analog voltages
beforebeinglteredbyapreliminaryanaloglow-passlteringstage.
The extremely high sample-rate to output-frequency ratio provides
DDS oscillators with the advantage of superior phase precision and
natural-sounding frequency modulation. Importantly, it also allows us to
avoid using the severe band-limiting, or “anti-aliasing”, of typical lower-
frequency digital methods. This means our oscillators are easily capable
of generating frequency content far above the limits of the human auditory
system, as is the norm with analog oscillator synthesis.

What is Binaural Synthesis?
In binaural mode, the Super Gemini features a true stereo signal path
in which its 20 voices are twinned to form either ten stereo ‘super
voices’insinglemodeorvestereo‘supervoices’indualorsplitmode.
Consequently, the left and right channels (and your ears) are each
assigned a complete synthesizer voice per layer.
Starting with the stereo oscillators, parameters of both channels of each
‘super voice’ may also be independently controlled, enabling you to create
gorgeousstereoimages.Theeectonthesoundrangesfromsubtle
to extreme stereo movement, resulting in an enhanced sense of spatial
positioning compared to conventional monaural signal chains.

QUICK START
The Super Gemini was designed for hands-on performance and
experimentation. Not only do we think it is a great sounding instrument,
but it also provides you with a pleasing immediacy when interacting with
the sound. All of the Super Gemini’s primary controls are accessible
directly from the front panel, making it an incredibly intuitive instrument
that will spark your creativity in the studio and on stage.
The upper two rows of the front panel feature individual sound shaping
controls for each of the two layers, allowing you to program and edit two
patches simultaneously in dual and split modes. The bottom row of the
front panel mainly covers shared controls for both layers, which enable
you to load a layer’s patch and to modify the arpeggiator, sequencer and
eectssettingsperlayeramongstotherthings.
To the left of the keyboard is the performance control section that
contains performance-related elements such as the bender, transpose
and portamento controls as well as a second LFO. To further increase the
expressiveness of your performance, the Super Gemini is also equipped
with a custom-designed ribbon controller and a 61-note keyboard capable
of polyphonic aftertouch.
The front panel of the Super Gemini.
Exploration and experimentation are downright encouraged, so feel free
to dive straight in and start creating your sounds. The best way to learn
about how the Super Gemini works is to get involved! You can always
come back later and read more about each of the Super Gemini’s sound
shaping tools in the subsequent paragraphs of this manual. We hope you
enjoy playing and tweaking the Super Gemini as much as we do!

Performances
A performance comprises a complete instrument setup, consisting of
two layers – an upper and a lower layer – each with its own patch (see
pages 19-24) and overarching parameter settings (see pages 78-82).
A performance is always loaded because it provides the framework for
individual sounds or patches. It can consist of one patch in single mode,
two stacked patches in dual mode, or two patches assigned to the left
and right halves of the keyboard in split mode. See pages 81-82 for more
details on each of these modes.
The MASTER VOLUME setting is not part of a performance and
must always be adjusted manually.
A total of 128 performances are accessible from the front panel. They
are organised in two groups (Aand B) of 8 banks (A-H) featuring 8
performances each. You can edit these or use the dedicated memory slots
to store your own performances.
Loading a Performance
First of all, make sure you are in performance mode. The Super Gemini
defaults to this mode when you turn it on, but otherwise it is activated by
pressing the button labelled PERF.
The performance mode button.
Pressing PERF gives you access to group A, indicated by the lit LED
above the letter A. To access the performances of group B, hold SHIFT
and then press PERF. The LED above the letter Bwill now light up.
Each lettered button (A–H) allows you to select a bank. Pressing a
numbered button (1-8) loads one of eight performances within a selected
bank.

The LEDs of buttons 1-8and A-Hwillashoncetoindicatethatthe
performance has been stored.
Storing a performance will overwrite the performance previously
stored to that location.
When you store a performance, you are essentially saving a
snapshot that contains copies of the patches in each layer. As
a result, any changes applied to any of the layers are also saved
without changing the original patches.
If you want to use a specic layer of a performance as part of other
performances, you need to save it as a patch. This makes the patch
banks the place to store your favourite or most important sounds.
See page 23 on how to store patches.

Patches
A patch is a stored set of parameters that determine the characteristics of
a sound. Patches are each loaded into one of the layers of a performance.
A total of 256 patches are accessible from the front panel. They are
organised in two groups (Aand B) of 16 banks (A1-H2) featuring 8 patches
each. You can edit these or use the dedicated memory slots to store your
own patches.
Loading a Patch
First of all, select the layer you want to load a patch into by using the
