Not necessarily your main instrument, probably never going to record it, but helps a lot with songwriting, working out chord progressions on the go. The main keyboard is monophonic but the machine has accompaniment on the left side. Separate control for the chords, the rhythm and the melody. It can record your melody line and play it back, not quantized. Some analog sounding drum beats named after music genres (Disco, Rock, Waltz etc) and some arpeggios. Would fit in a bag. And very cheap.
