Gocen Reads & Plays Printed Music Notation, Demoed At SIGGRAPH 2012

Optical Music Recognition research is maturing with changing times, but an interactive system for reading hand-written music notation and playing it in real time is a new. At the ongoing SIGGRAPH conference in Los Angeles, a project called 'Gocen' developed by Tokyo Metropolitan University demonstrated a unique system that lets users write musical notation and play instruments at the same time. The device is moved over the notation horizontally, when the system detects the size of the musical notation and interprets it as the control note velocity. If you press the 'manual play' button, the computer displays simplified form of these notes.

Users can change the instrument (piano, bass, drums, guitar etc.) and see how the note sounds differently with each device. There is an option fro recording too - you get to see each recorded note in a quantized timeline. The usefulness of this device will be best understood by the students who are at the beginning stages of their music lessons. Take a look at the video -
