Gamelan Sampul

A set of gamelan instruments that fit on your laptop sleeve so you can practice gamelan music on-the-go.


As part of my thesis, I built a portable practice gamelan instrument embedded in my laptop sleeve so I could rehearse my music anywhere that I carry my laptop. The Gamelan Sampul, which means 'envelope gamelan', features touch-sensitive pads that trigger noises that one would usually hear from real Javanese gamelan instruments. It also acts as a recording device, allowing users to keep an archive of their own and other players' musical style. I will also present a set of new sensors currently in development that give haptic and visual feedback as well as more accurate sensing of when it is hit.
