“Mogees currently uses two audio synthesis techniques — the first is physical modelling, which consists of generating the sound by simulating the propagation of the sound wave through different physical materials such as strings, membranes, or tubes using a piece of software called Modalys. The second technique is mosaicing, where the user loads a sound folder and then the audio coming form the contact microphone is analysed and the software looks for the closest segment within the sound folder. So if a sound folder of voices is loaded, touching the surface gently would provoke a whispering while scratching it will cause a sound similar to screaming voices.

The idea of using contact microphones comes from the desire to turn ordinary objects into percussive instruments. The goal is to allow musicians and performers to take full advantage of electronic music without losing the feeling of touching a real surface.”
