If you own a K2700, PC4 or PC4 SE, please sign up for Kurzweil Beta Testing Program.
It’s easy, doesn’t require much other than running newer OSs once in a while if you can. If you can’t (you are gigging, you don’t have the time) then there is no problem whatsoever.
And sometimes you get to test new features before everybody else get them, which is pretty cool.
To sign up, just write an email to firstname.lastname@example.org, email@example.com or firstname.lastname@example.org .
