Thanks for noticing my Eigenharp Alpha. I was lucky enough to get one of the first ones in the US. I can tell you that it is one of the most remarkable instruments I have ever seen. It is literally infinitely modifiable and supremely expressive. And unlike your average keyboard controller, this one can be played and configured standing up like a guitar. It is really amazing. The version in the picture is the flagship Alpha, there are two other models which are less expensive (software is the same for all). I highly recommend these instruments to anyone interested in reaching beyond the mundane controllers/keyboards and offering your audience something more interesting and more interactive than the usual midi fodder. Even though I bought mine immediately after its release from eigenlabs 2 years ago, there are many local retailers in the US ... ludlow guitars and BH Photo in NYC to name a few.
There is nothing like the Eigenharp ... it is a unique and magnificent new instrument.
