"SongFactory is a completely new way to record songs. You can record song demos in minutes, easily try out different song arrangements and even use it to accompany you as you practice."

"As well as providing traditional recording features, SongFactory can generate music to match your chords and tempo. The generated music isn't synthesized - it's created using samples painstakingly recorded by session musicians. You get your own session band working with you to create songs."
