Super 6 Polyphonic Hybrid Keyboard

When UDO Audio set out to design the Super 6, they wanted to prove that analog warmth and digital precision weren't opposing forces—they were a conversation waiting to happen. The result is a synth that feels equally at home recreating the lush polysynth textures of the 1980s and generating sounds that didn't exist back then.

The Super 6 is a 12-voice polyphonic hybrid synthesizer built around two FPGA-based wavetable oscillators per voice, sampled at 40MHz for pristine digital clarity. The first oscillator is the real star: a 7-core super-wavetable engine that generates a centroid oscillator alongside six dynamically detuned and phase-displaced sister oscillators, creating the signature "super" effect that spreads sounds across the stereo field with organic movement. The second oscillator handles FM, hard sync, suboscillator modes, and crossfading, giving you endless modulation possibilities. Both feed into a classic 4-pole analog low-pass filter with 24dB per octave rolloff, inspired by the SSM2044 design, paired with a voltage-controlled high-pass filter that can link for band-pass operation. The analog signal path includes a resonant VCA and dual ADSR envelopes, all routed through a flexible modulation matrix. Effects processing happens in the digital domain at 24-bit/192kHz resolution, with stereo chorus and delay that can be synced and modulated.

The keyboard is a 49-key Fatar with velocity and polyphonic aftertouch, expression and sustain pedal inputs, and MPE support for expressive controllers. The 64-step sequencer and multi-mode arpeggiator both sync to external clock, while 128 patch slots let you store your creations. The binaural architecture is the secret weapon: pairs of voices are assigned to left and right channels as "super voices," allowing independent parameter control and phase-displaced modulation that creates filter sweeps and tremolo effects filling the entire stereo field. You can also feed external audio through the stereo input with threshold-based envelope and LFO triggering, turning the Super 6 into a powerful effects processor.

Since its 2019 debut, the Super 6 has earned respect from both classic synth enthusiasts and sound designers pushing into experimental territory.
