Your New Composing Assistant! Each time an original melody or tune comes to mind, it may often require substantial expertise, equipment, and time to turn that idea into a complete song in the same way that a professional musician or arranger might do. Korg's microARRANGER offers an easier way for you to enjoy the satisfaction of composing original music.

Even with modest keyboard skills, you can simply choose a musical Style to match your idea, tap in the tempo, hold down the chords with your left hand and pick out the melody with your the right hand, and listen as your musical idea takes shape!
