I’m not promoting this, I just came across it and was fascinated and thought my IRD pals might find it interesting too. From what I can tell it’s not yet on the market, but here’s a YouTube video about it (they may have been at NAMM?) and I can’t find a website for it but there’s a Kickstarter page so it looks like they’ll need funding before starting production.
I thought I heard something about a database of songs to play along with, for practice etc. It can also be used for composition I think. Other than that, I don’t know much, just wanted to see if anybody else finds it interesting and possibly useful (once it actually comes out).
