Laser Pitch Detection system turns your axe into a luminous, latency-free MIDI machine (video)

Here's a fact you should remember about lasers: they make everything better. Even musical instruments. Anyone who has ever tried to use their trusty six-string as a MIDI controller knows the pain of the latency introduced by trying to convert string vibrations into digital signals. M3i's Laser Pitch Detection (LPD) system skirts this issue by running a laser beam under each string. Instead of detecting vibrations the optical pickup measures the distance between the diode and the depressed string, then converts that into a pitch. That not only means there's no delay, but also that no need to actually tune your instrument -- it combines all the laziness of Antares' ATG-6 with the class of Beamz. If you're curious, there's a demo video after the break.
