Transposes the keys very well without changing the tempo... But I would like to be able to save the song or email it to myself so I can put it on a CD... I would also like to remove the static... :/ Show more

Will buy full version if the light static is removed. Good if you want to turn any of your songs into a karaoke version to test your vocal prowess.

It works as in it changes the key and speed of a song but it gets REALLY annoying. You can't seek in a song, like fast forward and rewind. Also, whenever you load a song, it gets really fuzzy and there's a lot of excess noise in the background. I spent the $3 or however much it is because I was desperate and it gets the job done mostly theres just a lot of problems. Great idea! Just fix it. And not worth the money unless you're desperate like me.., Show more

For free you only get 30 seconds of the song. Also, you can only play and pause. There's no way to loop a section, or even just rewind or start over. Not very useful when practicing. Show more
