UDO Super 6 Grey

The Super 6 is a 12-voice polyphonic analog-hybrid synthesizer. A harmonious marriage of state-of-the-art FPGA digital hardware oscillators and voltage-controlled analog technology. It is flexible, immediate, powerful and refined with a gorgeous analog tone. Rich and evolving textures are easily teased from the unique Super-wave core and can be shaped and manipulated with the binaural analog signal path and flexible modulation capabilities. Robust, compact and versatile with solid and responsive controls – the Super 6 is a truly vibrant and inviting instrument that cries out to be played.

Oscillators

The Super 6 features two main FPGA-based oscillators per voice

DDS 1 (Oscillator 1)

FPGA-based Super-wave oscillator core sampled at 50MHz with a centroid oscillator and six sister oscillators that can be dynamically de-phased in the stereo field

Waveshapes: sine, sawtooth, square, triangle, noise and 16 user-downloadable alternative waveforms

Alternative DDS 1 waveform format:

• Single-cycle waveform with 4096 points
• 16-bit signed integer format samples
• Bandlimited at approximately 500 times the 4096-point fundamental frequency
• Binary file with no header data and file extension .ws6

DDS 2 (Oscillator 2)

FPGA-based algorithmic oscillator core sampled at 50MHz

Waveshapes: sine, sawtooth, square, triangle, noise, pulse

Can be hard-synced to DDS 1

LFO mode

Sub oscillator mode (can be activated when in LFO mode)

Pulse waveform with variable pulse width and PWM

DDS Modulators

LFO and envelope modulation of DDS 1 & DDS 2 pitch

Selectable ½  Super or full Super mode for DDS 1

Sister oscillator detune spread control for Super waves

Pulse-width control for pulse waveform

LFO and/or ENV 1 can modulate the sister oscillator detune spread for the Super waves and the pulse-width for the standard waves

DDS 2 to DDS 1 cross-modulation for deep FM Sounds

Audio Input

Stereo audio input that feeds through the VCA, VCF and effects section

Gate triggering of envelopes and LFO 1 based on audio input level with a variable-gain input stage

LFO 1

Main LFO with low and high-frequency modes, rate adjustable from 0.05 Hz to 20 kHz

Left-right phase control for stereo effects, harnessing the binaural sound engine

Can be free-running or reset on note press

One-shot mode allows LFO 1 to act as an additional envelope

Keyboard tracking mode for high-frequency LFO (useful for FM sounds)

LFO 1 can be mapped through the DDS 1 or DDS 2 audio path in either fixed or tracking high-frequency modes for use as a drone or a third oscillator

Can be synchronized with the sequencer and arpeggiator as well as an external clock

Mixer

Adjusts the mix-level of DDS 1 and DDS 2 audio signals

When in X-Fade mode, adjusts split point on the keyboard of crossfaded DDS 1 and DDS 2 (or audio input) signals

Voltage Controlled Filter

The SSI2144 reprises the SSM2044 of legacy chipmaker Solid State Micro Technology, which many believe to be the best-sounding analog synthesis filter IC ever produced. Based on Dave Rossum’s patented classic improved ladder topology, the SSI2144 allows rich tonal characteristics that showcase the very best attributes of subtractive synthesis.

Analogue 4-pole low pass self-resonant filter

Two levels of overdrive

High pass filter with fixed frequency or linked to low pass filter for a bandpass response

Selectable keyboard tracking modes with filter autotune for accurate keyboard tracking

Modulation by ENV 1 and/or ENV 2, LFO 1 and DDS 2

Voltage Controlled Amplifier

Analogue VCA with selectable fixed or variable envelope (ENV 2) modulation

LFO 1 modulation

Dynamics control for selectable velocity sensitivity

Envelopes

ENV 1: Invertible Hold-Attack-Decay-Sustain-Release, mappable through modulation matrix

Looping mode with selectable keyboard tracking for use as an LFO or FM source

ENV 2: Attack-Decay-Sustain-Release, multiple destinations

Keyboard and Controller Section

49-key Fatar mechanism with velocity and aftertouch

Two-axis bender with LFO trigger

Voice modes: Poly 1, Poly 2, Solo, Legato, variable size and type Unison

Keyboard-adjacent dedicated controls for bender DDS 1/2 pitch and VCF cutoff modulation

LFO 2 with rate and delay controls, selectable triggered and always-on modes

Variable portamento

Expression pedal and sustain pedal inputs

Playable spring-lever keyboard octave selector

MPE MIDI compliance with response to note on and off velocity, polyphonic aftertouch, polyphonic pitch bend and polyphonic expression

Modulation Matrix

Intuitive modulation matrix with pre-defined destinations and also mapping to a wide range of front panel controls

LEDs give clear feedback on mappings and modulation depths

20x audio-rate modulation computation

Arpeggiator/Sequencer

MIDI-syncable, multi-mode arpeggiator with smart-hold

MIDI-syncable 64-step sequencer with programmable note, rest, slide, accent and length tracks

LFO 1 and delay controls can be locked to the arpeggiator/sequencer clock

16 rewritable memory locations for storing sequences

Effects

Dual-mode stereo chorus using 24-bit 192 kHz processing

Syncable and modulatable stereo delay with 24-bit 192 kHz processing

Performance

128 rewriteable patch memories with 64 factory patches and 64 empty slots for user patches

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 effect on the sound ranges from subtle to extreme stereo movement and an enhanced sense of spatial positioning relative to conventional monaural signal-chains.
