KEYed user interface: Tools for expressive music production

We introduce the KEYed user interface, an ergonomic and intuitive method for controlling music composition software from a piano controller by adding a momentary foot switch. The piano keyboard mappings provide increased speed and intimacy with the controls for enhancing the expressivity of the composer during the composition. After describing the current practices and design of the system, we discuss the results of our early user testing during various editing tasks, comparing the conventional input device with ours.
