This is a great product. When it first came out I had both the iPad and Desktop versions. iPad for YouTube and Desktop for you music library. Everything that the working musician needs to learn a song. Slow it down, loop the section your trying to learn, or even change the key if you can’t sing it in the key that it is in. Easy to use and useful to the Nth degree. Want to learn that riff that a musician plays, this is the ticket. Thanks Shareware for having this download. Slim
