Calling itself the "most expressive electronic instrument ever made," the Eigenharp Alpha from Eigenlabs will certainly cost you a pretty penny. Designed to give every musician an impressive musical performance (assuming you can actually play, that is), the Alpha supposedly offers a "limitless range of sounds." The instrument can play and record loops, change scale and key, transpose, alter tempo, create arrangements, program beats, and switch and layer between sounds — all while performing live. It does all of this using its 120 sensitive keys, 12 percussion keys, two strip controllers and a breath pipe (which is actually optional). Pretty much everything you need comes in the box, including a case, various cables, a base, and a DVD with tons of media and sound files on it. The Alpha definitely seems like something only a seasoned professional should play with, maybe someone in Elton John's band, but if you can figure this thing out, you can probably play anything.
