UDO Audio Super 6 ST49 Blue

The UDO Audio Super 6 ST49 Blue is a 12-voice analog-digital hybrid synthesizer featuring a built-in binaural modulation system, filtering based on a 4-pole analog resonant filter, LFO modulation, an arpeggiator, a 64-step sequencer, and a wide range of inputs and outputs including 2 x 1/4" TRS, 1 x 1/4" headphone out, modulation matrix, MIDI In/Out/Thru, and USB-B.

The Super 6 ST49 Blue by UDO Audio is an advanced version of the original Super 6, designed for professional performance and deep sound design. The inclusion of polyphonic aftertouch enables expressive control over each note in real-time. ST49 merges digital precision with analog richness and features a 49-key Fatar semi-weighted keyboard for accurate articulation.

The dual-oscillator structure is powered by FPGA-based digital generators. The first oscillator uses a super-wavetable core with 6 phase-aligned "sister" waves to deliver a massive stereo field. The second oscillator supports pulse width modulation and sync. Both oscillators feed into an analog VCA and a 4-pole resonant filter, allowing precise control of cutoff and resonance. Cross-modulation and FM capabilities unlock rich harmonic textures.

The binaural signal path enables individual stereo processing per voice, enhancing spatial depth. The LFO has a wide frequency range (0.05 – 20,000 Hz), key tracking, and one-shot mode. The modulation matrix allows for complex routing and modulation assignments.

The UDO Super 6 ST49 control panel includes an assignable pitch bend, portamento fader, octave switches, and modulation wheels. Onboard Delay and Chorus effects add sonic depth without needing external processors. The built-in arpeggiator and 64-step sequencer are fully syncable via MIDI, greatly expanding live performance options.

The rear panel features a 1/4” TRS audio input, stereo outputs, MIDI ports, and a USB-B connector. Additional pedal controls can be connected via 2 x 1/4" TRS jacks. The combination of modulation matrix, analog VCA, and digital oscillators makes the ST49 an ideal tool for both sound design and live use.
