Band in a Box works a lot differently from an Arranger Keyboard. For one thing, the Arranger Keyboard is designed to be used in Realtime. Band in a Box is designed such that the user must first enter the chords to the song on the Chord Grid. Then, when you hit the Gen/Play button, Band in a Box uses intelligent algorithms to decide which phrases or variations to play over those chord changes. Each time you hit Gen/Play can therefore generate a slightly different performance.

One can duplicate some of the things the style variations of the arranger keyboard can do within a song by assigning style changes at the differing bars, though.
