This is a fantastic app if you are looking to practice soloing over chord changes. You just program the chords in whatever configuration youd like and start playing... Its that simple. For jazz players, this is superb. It not only lets you use seventh chords in any key, but also provides extensions, all the inversions, and even some altered chords to challenge your playing. Moreover, you can choose from dozens of styles, from Latin to electronica... Just a great, useful tool.
