NoteWorthy Composer lets you create, record, edit, print and play back your own musical notation scores. You can import and export standard MIDI files, use the computer keyboard or mouse for notation editing, and selectively add or remove accents, slurs, staccato, beams, triplets, and accidentals through toolbar buttons. You can use an external MIDI keyboard for real-time and step-time entry of your music. A transpose feature can be used to transpose parts from one key to another.
