In this paper, we present the BladeAxe: an iPad-based musical instrument leveraging the concepts of augmented mobile device and hybrid physical model controller. By being almost fully standalone, it can be used easily on stage in the frame of a live performance by simply plugging it to a traditional guitar amplifier or to any sound system. Its acoustical plucking system provides the performer with an extended expressive potential compared to a standard controller. After presenting an intermediate version of the BladeAxe, we’ll describe our final design. We will also introduce a similar instrument: the PlateAxe.
