Which method is NOT one of the ways to input music into desktop music publishing software?

The method not utilized for inputting music into desktop music publishing software is the use of a virtual piano. While virtual pianos are often integrated within music software for playback or practice purposes, they do not serve as a method for directly inputting notes into a score. Instead, desiring input typically involves recording audio through a microphone, employing manual note entry for precise control over the score, or utilizing scanning technology to digitize printed music. These methods allow for effective conversion of musical ideas and notation into a digital format.
