What it is
Harmony Assistant is desktop software for computer-assisted music composition and editing. It supports MusicXML, MIDI, parts extraction, and tablature, and runs on Linux, macOS, and Windows. Users can enter scores with a mouse, computer keyboard, or external MIDI keyboard, then work in full-page editing or engraver mode for score layout. Its embedded SoftSynth contains hundreds of instruments and can play through basic sound cards without external MIDI hardware. The program loads and saves MIDI, WAV, AIFF, MP3, OGG, TAB, ABC, and XML files. The embedded MyrScript language lets users add features. Documents can be password-protected and allowed to play without modification. Virtual Singer is an additional module for singing lyrics in multiple languages and voices. The trial has no time limit, but saving is disabled and printing is limited to one page while unregistered. A registration code is a lifetime license for one platform and includes future versions.
