The software makes use of multiple instrument tracks which follow standard staff notation, but also shows the notes on tablature notation. It gives the musician visual access to keys (banjos, drumkits, etc.) for the song to be composed, and allows live previews of the notes to be played at a specified tempo. It allows for certain tracks to be muted and provides dynamic control over the volume, phasing and other aspects of each track. Included in version 4 onwards is a keyboard that allows pianists to add their part to a composition.
