What is good about this, you ask? Read on… – SoundPrism Review

I get annoyed at being accosted to write reviews. Because of this pestering, -1/2 star; so, really 3 1/2 stars. In this rare case, however, I am willing to say this is a nice app. Being a bit of a keyboardist, it must be said that the notes are not sequential as found on, say a piano. Albeit, the arrangement of thirds is unique; with application of basic music theory, chordal structure is there at your fingertips. I enjoy the various sound packs available, and suggest the purchase of the group to save money—most are good.
