Music, MIDI and mobile? Seen that before, right? Well, yeah, but sometimes something comes along that surprises everyone. Artiphon's Instrument 1 is one such thing. And after all, there's more than one way to crack a nut. Artiphon's method involves creating a high-quality muli-instrument device that uses an iPhone or iPod touch as its brain. So, this is no plastic (bear with us) "appcessory." The Instrument 1 is made out of special quality African hardwood, and centers around an intentionally ambiguous design. There is a pair of high-quality custom speakers that give impressive 30W onboard sound. There is, of course, a line out and MIDI in / out too. The prototype we saw today doesn't have a built-in battery, but final production models will, making this a truly portable, complete solution. Dr Mike Butera, the firm's founder, was keen to explain to us that this is intended not to replicate one specific device (though it does a great job of guitar, violin, banjo and more), but rather to enable musicians to be able to work in a way they want to. The Instrument 1 works with any core MIDI enabled app, but there are plans to release a companion app for more detailed / custom mappings in the future. We got a private tour of the device, to tip-toe past the break for more.
