To the tech-minded, it's innovation. To traditional musicians, it might just be blasphemy. The Misa Digital Guitar has taken the strings out and put a touchscreen in their place.
According to the manufacturer's site, the Misa Digital Guitar is not a replacement for the "analog" string instrument, but rather to morph sounds "in an infinite number of ways."
So instead of strings, this digital instrument (self-proclaimed as a MIDI controller) has 24 frets combined with a large touchscreen. The open-source software is Linux-powered, and programmers have the ability to alter the interface for specific functionalities.
Misa has published a video on YouTube so you can see the Digital Guitar in full action.
Guitar Hero is a fun, revolutionary game that gave new life to gaming (and the music industry). I'm not quite sure where this falls, or if it will even work. It looks more like something I'd see in a Final Fantasy game rather than something I'd want to play in real life.
But maybe it's just crazy enough to take off.
