One of the highlights of this years Superbooth 19 was the U.D.O Audio SUPER 6 Synthesizer, a 12-voice polyphonic, binaural analog-hybrid Synthesizer. Very exciting here: two Synthesizer worlds bounce beautifully on one another: state of the art digital synthesis based on FPGA and classic high-quality analog technology. Both do not compete but harmonize together or as U.D.O describes: a harmonious marriage.

U.D.O Audio recently released the complete specs of the SUPER 6 Synthesizer with all the details you need to know. An interesting point can be found at the end of the features list: “unlock multi-timbral mode (not on release)”. So we can assume that the SUPER 6 will grow into a multi-timbral hybrid synth in upcoming firmware updates.

In addition to the entire feature list, the developers have sent photos in the press release, where you get an insight into the development and the first prototype of the SUPER 6.

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”

On  Superbooth 19, I have interviewed the main developer and Axel Hartman, the designer of the interface. Check out below the video from SB 19.

U.D.O Audio SUPER 6 will be available in Autumn 2019 for an estimated price of 2000£ incl. tax.
