Vocaloid piano! I would've done it with voice but.. that's impossible. Maybe another day~ XD

I use it to tune my guitar lol~

Promotion time: here's some bluesy piano rock to play along to facebook.com/camillemaisound. (:

And here's a link to a similar deviation I did, only with Miku's voice from Vocaloid instead of piano sounds! Mikupiano XD
