Excellent

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 a serious App for Musicians

This is not yet another sheet music App that tries to tap you away from paper with useless promises such as teaching you how to play! This is a real App for amateurs practicing music who wish bring excellence to their daily practice. You play with orchestras and high quality back tracks, high quality sheets and expanding repertoire.

Amazing

I have been playing with this for a year now and can’t practice without it. I play flute and recommend it to anyone from amateurs to professionals looking for an accompaniment for solos.
