INFORMATION
OVERVIEW
The UDO Super 6 is a 12-voice polyphonic analog and digital hybrid
synthesizer. By combining characteristics of the best of vintage-era
classic synths and state-of-the-art modern synthesis technology
(more about that below), it was designed to be a exible, powerful and
immediate instrument that provides you with a gorgeous sound.
DDS Oscillators
Direct Digital Synthesis is the signal generation method employed by
both oscillator cores of the Super 6. At its centre is a clock signal – three
orders of magnitude higher than typical audio sample rates. The clock
signal increments a counter through thousands of indices in your choice
of waveform, selecting the appropriate sample to output every twenty-
billionths of a second with interpolation lling in the gaps between
samples at dierent oscillator frequencies. The samples produced by our
numerically-controlled oscillators are then transformed to analog voltages
by a DAC, one for each oscillator, which operates at the same clock rate
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. It also, importantly, precludes us from
needing to deploy the severe band-limiting that is necessitated by
aliasing constraints of typical lower frequency digital methods. Thus our
oscillators are comfortably capable of generating frequency content far
above the upper-frequency limits of the human auditory system as is
the norm with analog oscillator synthesis.
What is Binaural Synthesis?
In Binaural mode, the Super 6 features a true stereo signal path
in which its twelve voices are twinned to form six stereo ‘Super’
voices. Consequently, the left and right channels, and each your ears,
are assigned a complete synthesizer voice. Starting with the stereo
oscillators, parameters of both channels of each Super voice may be
independently controlled, facilitating you the player to create gorgeous
stereo images. The eect on the sound ranges from subtle to extreme
stereo movement and an enhanced sense of spatial positioning relative
to conventional monaural signal-chains.
