What capability? The fundamental thing about this seems to require that there's not any direct way to play notes. So what would the keyboard be used for?

I must have misunderstood something. I'm a musician and have never seen a tunable keyboard, which I thought, upon seeing this, would be useful. I guess I'm dense, because I'd still be interested in this as an option in a physical keyboard.

But I am an illiterate musician. Perhaps that's were the misunderstanding arises. I favor Eastern instruments too.

No problem. I know that you can use a traditional midi controller and use computer-based synthesizers, some of which support a wide variety of tuning options. I never got too much into that myself. When equal temperament is too constraining for me, which is not often, I can get what I need with the bend wheel.

I was just thinking maybe I was missing some way of "performing" using this post. It seems more like random and emergent as far as I can tell.
