INTRODUCTION When designing an augmented acoustic instrument, it is of- Two common motivations for designing augmented instru- ten of interest to retain an instrument's sound quality and ments are to extend the sonic capabilities of an existing nuanced response while leveraging the richness of digital instrument, or to repurpose the player's existing skill and synthesis. Digital audio has traditionally been generated technique on a traditional instrument. In contrast to tra- through speakers, separating sound generation from the in- ditional acoustic instruments, where sound production is strument itself, or by adding an actuator within the instru- inherently tied to physical construction and energy input ment's resonating body, imparting new sounds along with from the player, it is common with developing digital or the original.
