Nuage is a professional-use production system for controlling Nuendo DAW software. When developing this system, we decided not to base it on any existing models, and instead started from scratch in a quest to find the best solutions for adding sound to video in postproduction. We incorporated advice from leading professionals in Japan and around the world while creating mock-ups of various shapes, experimenting with the height and angle of the mixing desk, the angle of the video monitors, and other aspects. As designers, our most important objective for the Nuage system was to make its op-erations fully compatible with the Nuendo software displayed on the screens, so that the software’s vast number of advanced functions could be used intuitively. To do that, we employed numerous techniques to give engineers the sense that the boundary separating hardware and software had practically disappeared. These techniques included matching the lettering and coloring appearing on the main panel with that displayed by the software, and reproducing the layout of the controllers on the software screens. We also worked to make the physical controllers comfortable to operate. We tested the shape and movement of the precision-machined stainless steel jog wheels to make sure that resolution is high enough for video to be shifted frame-by-frame via delicate movements of the fingertips. We also equipped the unit with touch sliders that allow channels to be scrolled just by sliding the finger. The palm-rest is made with real leather, not only for the sake of texture but also to give an organic feel to the unit’s solid design. In this way, we designed this sophisticated professional production system with a cool, appealing look.
