The project, called Gocen, is described by its creators as a "handwritten notation interface for musical performance and learning music." Developed at Tokyo Metropolitan University, the device can read a printed (or even handwritten) music score in real-time using optical music recognition (OMR), which is sent through each computer to an audio mixer, and then to a set of speakers. The interface is entirely text and music-based -- musicians, if you can call them that, scan an instrument name on the page before sliding over to the notes, which can be played back at different pitches by moving the reader vertically along the line. It certainly won't replace an orchestra anytime soon -- it takes an incredible amount of care to play in a group without falling out of a sync -- but Gocen is designed more as a learning tool than a practical device for coordinated performances. Hearing exactly how each note is meant to sound makes it easier for students to master musical basics during the beginning stages of their educations, providing instant feedback for those that depend on self-teaching. You can take a closer look in our hands-on video after the break, in a real-time performance demo with the Japan-based team.
