For #3, it doesn't even have to be that fancy for expert players/song writers. One of our investors is Matt Bellamy, the lead guitarist/vocalist of Muse. Generally when he wants to write a song, he goes for the piano to figure out the chord progression. It's much easier to compose on the piano because all the notes are in front of you in sequential order (black and white keys). After he figures out the chord progression, he'll switch to the guitar. If he was to start composing on the guitar, there is a higher amount of cognitive load that is based on the physics of vibrating strings and his ability to physically shorten them by pressing your fingers on metal/nylon. With our instrument he gets best of both worlds, a guitar interface, but every button is a chord in any key/scale. Basically, you now have a chord encyclopedia (like omnichord), but once he figures out the chord progression, he can switch to traditional mode and do the crazy stuff that he does all on one device.
