Just bought this app, looking for backing tracks that I can edit out the instruments and vocals I don’t need (those played by our three piece). As far as I can work out this is just a music player that can alter pitch and tempo! Am I missing something?
Well and lyrics display, autoscrolling, the whole queueing and playback management and a bunch of other stuff you need on stage 😉
But removing vocals is not something the app can do. I would recommend you take a look at https://www.karaoke-version.com to purchase playback tracks to use with Stage Traxx.
