Fretwizard I agree, the version 3, is very intuitive, easy to work with and have many different choices, to suit the most demanding musician/Singer.
The que is very smart, and among many possibilities, you change everythng during play, even change playlist, and it the lyrics are swell.
I find the program to cheap, a adequate price, would be around 60-80 Euro.
My studio and the plugins, costs a lot more, but Peters superb program, Bess the most of them.
Hopefully, as a user, read and try, and probably you find a suitable solution. Some people, the mostly, have an attitude to stay in the familiarize, but a new version, is and should be, a new version.
Good work Peter!
