UDO Audio Reveals Details For Super 6 Synthesizer
Rounik Sethi on Sat, July 20th 0 comments
Super 6 made its official welcome to the world at Superbooth 2019 in Berlin. The 12-voice poly hybrid synth caused quite a stir. Here's the latest info on this gorgeous sounding synthesizer.

The Super 6 is a 12-voice polyphonic, Binaural 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-Wavetable core and can be shaped and manipulated with the binaural analog signal path and flexible modulation.  Robust, compact and inviting to pick up and play with smooth, solid and responsive controls throughout, it cries out to be played.

The Binaural refers to the twin synthesizer signal paths.  In Binaural mode, each channel ‘ear’ has a complete synthesizer voice.  You can detune (and de-phase) the left and right oscillators, amplitude and filter (and indeed other parameters) relative to each-other.  The effect is subtle to extreme stereo movement and an improved sense of 3D positioning relative to conventional mono signal-chains panned at the output.  It has in this sense 6 “Super voices” that each use two “conventional” voices, hence “Super 6”
