Designed for use primarily with guitar, the Trio can analyze up to three different chord progressions and, having worked out the key, time signature (3/4 and 4/4 only), length, tempo, number of bars, feel and constituent chords, it instantly creates, plays, loops and varies bass and drum parts that fit those sequences.
On top of that, those parts can be played in any one of seven different Genres, each of which contains 12 distinctly different Styles, nine in 4/4, and three in 3/4.
