Our verdict on Canorus

Canorus is a free, GPLv3-licensed desktop editor for writing and editing musical notation. It is aimed at musicians who want score-writing tools on Windows, macOS or Linux without a paid plan. Its documented capabilities include note entry, lyrics and transposition, making it relevant for composing or editing scores rather than for a broader music-production workflow.

File handling is a notable part of its scope: Canorus supports import and export of multiple formats, including MusicXML, and offers MIDI input and output. Scripting support and a Python integration provide another way to extend or work with the editor. For printed output, it relies on LilyPond for score preview and printing, and can export to LilyPond. That makes it a better fit for someone comfortable with a LilyPond-based output path than for someone seeking an all-in-one notation environment with a wider feature set.

The project is open source and free, but its repository describes it as under heavy development; feature coverage and release maturity may vary. That caveat matters for anyone depending on a predictable, mature editing workflow. Choose Canorus if free desktop score writing, MIDI and MusicXML support, and LilyPond output match your needs. Consider another editor if you need broader notation features or a more established release cadence.
