With the advent of the personal computer since the 1980s, traditional music engraving has been in decline, as it can now be accomplished by computer software designed for this purpose. There are various such programs, known as scorewriters, designed for writing, editing, printing and playing back music, though only a few produce results of a quality comparable to high-quality traditional engraving. Scorewriters have many advanced features, such as the ability to extract individual parts from an orchestral/band score, to transcribe music played on a MIDI keyboard, and conversely to play back notation via MIDI.
