Music production on traditional instruments creates vibrations that are perceived via hearing and touch. This is particularly true when producing music on a violin where the vibrations transmitted to the chin helps the musician to hone-in the tone quality. In contrast, modern music synthesizers create high quality sounds without including relevant haptic content. We present the implementation of a haptic sound synthesizer which creates sounds and vibration patterns in real time rendered both acoustically through headphones and haptically through an ultrasonic surface display. The aim of our device is to further investigate the interactions between synthetic haptic textures and sounds.
