Overview of Harmony Assistant 9.9.9i:
Most musicians and composers eventually hit the same wall. Their notation software cannot play back dynamics properly. Their sequencer does not understand score symbols. Their tablature generator has no idea about lyrics. Their audio editor cannot talk to their MIDI files. And before long, they are juggling three or four different programs just to finish a single piece of music.
Harmony Assistant 9.9.9i Full Version was built to eliminate that juggling act entirely. Developed by the French software company Myriad, it is one of the most comprehensive all-in-one music composition and notation tools available — combining a professional score editor, digital synthesizer, auto-accompaniment arranger, tablature generator, audio recorder, karaoke engine, and even a vocal synthesizer into a single, deeply capable application.
Harmony Assistant is a professional-grade, computer-assisted music composition and editing application. It is Myriad’s flagship product — the most feature-rich application in a lineup that also includes Melody Assistant, PDFtoMusic, Virtual Singer, and OMeR.
At its core, Harmony Assistant is a powerful score editor — but describing it that way understates its scope significantly. It includes what is usually found by owning several separate programs: a full notation editor with page and engraver mode, a built-in digital synthesizer, an automatic accompaniment arranger, a drum pattern manager, a digital audio recorder and sound editor, a tablature editor for stringed instruments, a karaoke system, a chord diagram library, and MyrScript — an embedded programming language that lets you extend the software with your own custom features.
Harmony Assistant can be downloaded and evaluated with no time limit. In the unregistered trial version, saving is disabled, and printing is limited to one page. Purchasing a license unlocks all features completely, and all future updates are included free of charge.

Conclusion:
Music software tends toward specialisation. Notation programs do not sequence. Sequencers do not typeset. Tablature tools do not generate accompaniment. Audio editors do not understand harmony. Most musicians accept this fragmentation as the price of working with best-in-class tools.
Harmony Assistant challenges that assumption. By combining professional score notation, a built-in synthesizer, automatic accompaniment generation, drum pattern management, digital audio recording, tablature generation for dozens of instruments, karaoke support, chord analysis, vocal synthesis integration, and a full embedded scripting language in a single perpetual-license application, it offers a breadth of capability that is genuinely rare at any price point — let alone for a one-time purchase with free lifetime updates.
Whether you are a composer writing orchestral scores, a guitarist notating arrangements with tab, a choir director building rehearsal materials, an educator creating music theory exercises, or a hobbyist who simply wants to bring musical ideas to life in a complete and capable environment, Harmony Assistant deserves serious consideration.
Its depth rewards the time invested in learning it, and its support for Windows, macOS, and Linux — along with its broad format compatibility and long development history — makes it one of the most dependable and versatile music composition tools available to independent musicians and educators today.
