UDO Audio / Super 6 Desktop

SUPER 6 DESKTOP is a 12-voice polyphonic binaural analog hybrid synthesizer. It combines cutting-edge FPGA digital oscillators with voltage-controlled analog circuits often used in vintage equipment to produce gorgeous analog sounds.

The rich sound quality, which combines delicacy and power, is formed by a unique super wave table core, binaural analog signal path, and advanced modulation. Using the sophisticated control panel, players can freely create sounds according to their overflowing sensibilities.

Pulse width control of pulse wave
Detune spread modulation by super waveform sister oscillator, pulse width of standard waveform can be modulated using LFO and/or ENV 1
Deep FM sound by cross modulation from DDS 2 to DDS 1

■Audio input
Stereo audio input via VCA, VCF and effect section
Variable gain input stage allows envelope and gate trigger of LFO 1 according to audio input level

■LFO 1
Main LFO can be set to low frequency or high frequency mode, rate can be adjusted from 0.05 Hz to 20 kHz
Stereo effect using binaural sound engine with left and right phase control
Free running or reset by note on
One shot mode allows LFO 1 can act as an additional envelope
Keyboard tracking mode for high frequency LFO (useful for FM sounds)
LFO 1 can be mapped in fixed rate or trackable high frequency mode through the DDS 1 or DDS 2 audio path and can also be used as a drone or third oscillator
Sequencer and arpeggiator can be synced to an external clock

■Mixer
Adjusts the mix level of the DDS 1 and DDS 2 audio signals
Adjusts the split point on the keyboard for crossfaded DDS 1 and DDS 2 (or audio input) in X-Fade mode
Voltage-controlled filter
The SSI2144 reproduces the SSM2040 from legacy chip maker Solid State Micro Technology, which many believe to be the best sounding analog synthesis filter IC ever made. The SSI2144 is based on an improved ladder topology patented by Dave Rossum, allowing for a rich tonal character that represents the best of subtractive synthesis.
Analog 4-pole low-pass filter (can self-oscillate)

2-stage overdrive

Fixed frequency high-pass filter or band-pass response linked to low-pass filter

Selectable keyboard tracking modes and filter autotune for precise keyboard tracking

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