I have been using it for the past several months, and it has helped me immensely during my performances.
Im a pro keyboard player/vocalist who needs to go back and forth between live playing and using backing tracks.
Finally Im able to focus on the performance completely without having to worry about stopping a track thats being played.
Sean B, the creator of the app also has been very helpful with all the timely replies to all my email.
It is worth every penny!
