I’m not really interested much in synthesizers, but I came across this and it intrigued me, and it took away my usual practice time. I know nothing about synths, but I know about pitch bending and the wheels and benders. This is a new concept that eliminates all that and puts it all in the keys themselves. You can bend individual keys, not just all of them as before. But there’s much more. I’ll give you a few links so you can see. It’s still a prototype but in production. I don’t know what I’d do with it, but it’s really interesting. If you’re interested., there’s a discount on the price until December 31. (No, I am not in any way affiliated with this company.
