Very good, played my favourite bouzouki songs, removed the vocals and then sang and played my bouzouzki with it. Just the background music. If there are any free updates please inform me. Excellent. I'm English, I live in Cyprus.

Awful Piece of Crap

There are so many other audio apps that are far superior that this example of cow manure. The vocals can STILL BE HEARD though reduced and the music has an awful swooshy sound meaning it is NOT a clean job. App released as half-done / half-assed. It is better to pay for something good that receive something free that is just bad. Uninstalling immediately!

Not bad at all !!!

This app is not bad at all. Anyway you can't expect it to take away the vocal correctly, no software dose this! I actually enjoyed using this software because it was able to open my Mp4 video Karaoke songs! Don't get excited! it dose not play the video, but plays only the audio. You can still change pitch and that was the good surprise. I have two suggestions for this software: 1- It would be great if it actually played the video files and we could change pitch (transpose) our video karaokes with it. 2- This one is a MUST! There should be volume control within the app! There is no way to change volume! you have to get back out on windows to do that!

Awesome App!

The vocal removal works very nicely on most of my music and is great fun for singing along. And now the pitch shift allow me to get the song in my singing range. All in all, a sweet app!

Great for light fun

Wish you could key in on frequencies you want to keep so you hear more of the music

Just took out the bassline!

All it did was take out the bass, and essentially cranked up the treble without doing sh!t to the vocals... took all the good parts out of the music I was trying to get. :(
