The little I’ve seen on this app is impressive. For those missing Cadenza this could be the new replacement. Can’t wait till more music is added. Basically it’s a piano accompaniment to your practice. Great potential.

Finally !! The ultimately MMO App
I’m a great fan of music minus one, it’s very useful for all levels of musicians, for learning and for having fun too. This app (this incredible app) is what i was waiting. Simple and ingenius. You choose an instrument, the piece and in a few seconds the app will download it and it’s ready to play…and the special thing is then, at the same time, it record your sound. Another cool feature is the possibility to change the “tempo” (speed) so you can practice slowly and after play at the right tempo.
