From the looks of it, if you attach a Concert Hands system to your piano it'll almost play it for you. Almost. The goal here is to guide you along, using a pair of sliding wrist-cuffs and a 10-finger feedback system, which gently pulses each individual finger when it's time to hammer a key. It relies a lot on muscle memory, and honestly looks like something they'd use to torture Rebel scum to find out which planet the base is on.
We weren't about to reach Concert Hands, but we've got some questions: Does it work with any song? It mentions coming with a library — we imagine it'll only be able to help you learn from that. Also, price is a big question. We'll let you know if we hear back.
