Music from the mundane [Resources_Hands On]

The Ototo board is an invention for musical innovators; it is to would-be creators of playable instruments what a prototyping board is to circuit builders. The board makes it easy to connect both everyday objects and a wide range of analog sensors to a music synthesizer. Any vaguely conductive surface (metallic duct tape, the skin of a fruit, and so forth) becomes a touch sensor once wired to one of 12 large pads on the board, which correspond to one octave of notes. Additional sensors can be plugged into any one of the four headers, which provide 5 volts, a ground, and a voltage-sensing input. The inputs from these can alter the pitch, amplitude, and timbre of sounds. There´s a built-in speaker, and a stereo headphone jack can send sounds to an amplifier. · But the most powerful feature of the Ototo–what really elevates it from toy to tool–is that when you connect it to a computer via the board´s Micro–USB port, it functions as a musical instrument digital interface (MIDI) controller. This means it translates both key touches and analog sensor values into a stream of commands for software instruments. MIDI is the universal language of digital musical instruments, and it was this feature I was most eager to explore. In particular, I was wondering whether it could help me play a beautiful violin romance by Antonin Dvorak, even though I´ve never had a lesson. · Yuri Suzuki and Mark McKeague, the creators of the Ototo (which was developed along with Naomi Elliott and Joseph Pleass), are cofounders of the London design firm Dentaku, and the board reflects their artistic interest in encouraging people to interact with sound and music in new ways. The video that they and their friends made to demonstrate the first prototypes of the Ototo early last year showed instruments made from cardboard, vegetables, and bowls of water. It´s cool stuff, if not practical for serious music making.
