Our verdict on Flat
Flat brings music notation, score playback, and tablature into a product for composers, arrangers, educators, and musicians. Scores can be created, edited, shared, and printed in a browser, with desktop and mobile apps also available. Its real-time collaboration makes it especially relevant to teams working on a score together, while MIDI device input and individual-part export support composition and arranging workflows.
Collaboration and notation exchange are central strengths. Multiple people can edit scores in real time, and tablature is synchronized with standard notation. MusicXML and MIDI import are available on Flat Basic; Flat Power adds export in both formats without branding, as well as customizable layouts and notation. The product also supports playback, audio export, MIDI output, and individual part printing and export. Offline composing with synchronization is available, and listed integrations include Google for Education, Microsoft Office 365, Canvas, Soundtrap, YouTube, Vimeo, and SoundCloud.
The free Flat Basic plan includes 30 instruments and up to 15 scores, with exports and printouts carrying Flat branding. Flat Power is listed at $9.99 per month or $49.99 per year, with unlimited scores, 180+ instruments including HQ instruments, and further capabilities such as advanced playback and custom instruments; the annual listing also includes cross-device synchronization and PDF import credits. A lifetime option is listed, without a price stated here. Choose Flat if shared browser-based score work, tablature, and cross-platform access fit your process. If your work depends on unbranded exports or more than 15 scores, the Basic plan will not suffice; consider Power instead.
