This is the kind of thing you only ever find at NAMM. The Neuman Synthesizer concept is a crazy looking touch screen, with a built in keyboard.
The Neuman uses Kontakt libraries at the moment and the touch screen interface is using JUCE, however in the future they want to develop their own hardware to run the synth end of this concept.
