Flat vs TuxGuitar

Flat is music-notation software for writing, editing, playing back, and collaborating on scores. It runs on the web, iOS, Android, Mac, and Windows, and supports MusicXML and MIDI import and export. Users can compose, edit, and play scores offline; cloud sync requires Flat Power. Multiple users can write, edit, and comment on the same score from different devices in real time. The free plan includes essential notation tools, playback, and collaboration, but is limited to 15 scores. Flat Basic lists 30 instruments; Power includes more than 180, including HQ studio instruments, alongside unlimited scores and advanced playback. Flat Power costs $9.99 per month or $49.99 per year. The desktop app is free to download and use, with a 15-score cap on its free plan. PDF import requires Flat Power or paid credits, while desktop exports include PDF, MP3, and WAV. Flat for Education integrates with Google for Education, Microsoft Office 365, and Canvas and has a free one-month trial. Personal accounts have a minimum age of 13 in most countries.

TuxGuitar is a free editor and player for multi-track guitar tablatures, available for Android, Linux, macOS, and Windows. It supports tab and standard notation, MIDI, and playback, and can open Guitar Pro, Power Tab Editor, TablEdit, and MIDI files. Versions 2.0.0 and later use a format that older TuxGuitar releases cannot read, though tablatures can be exported in the older format.
