TypeNote
Load sheet music in any format. Start typing. TypeNote plays the next note — every keystroke, in any app, with <8ms latency.
Sequential mode maps your whole keyboard to the score. Every keystroke advances the song — perfectly in time, perfectly in tune.
Jianpu numbered notation, MusicXML from MuseScore or Sibelius, and standard MIDI files. Or type notation directly in the built-in editor — no import needed.
256-frame buffer. Key to sound in under 8 milliseconds.
Full General MIDI — piano, strings, brass, woodwind, synth.
No dock icon. No app switching. TypeNote is one click away — always on, never in the way.
The built-in editor uses Jianpu — a numbered system where 1–7 map to Do through Si. No staff lines. No music theory required.

TypeNote never touches the network. Everything stays on your Mac.
TypeNote captures no personal data, telemetry, or usage statistics. Not now, not ever.
After download, TypeNote makes no outbound connections. No analytics pings, no update checks, no servers.
Audio synthesis, score parsing, and key detection all happen entirely on your device using native macOS APIs.
Input Monitoring is required so TypeNote can hear keystrokes in other apps. Accessibility permission is optional — enable it only if you want Smart Mute, which silences TypeNote when a text field is active. Both can be granted from System Settings without reinstalling.
Jianpu (.txt) for numbered notation, MusicXML (.xml, .musicxml) exported from MuseScore, Sibelius, or Finale, and MIDI (.mid, .midi) files. You can also write Jianpu notation directly in the built-in score editor — no file needed.
Enable Smart Mute and TypeNote goes completely silent whenever a text field has focus — code editor, browser, documents, chat. It only plays when nothing is waiting for your keystrokes. Use the menu bar toggle to pause instantly.
Click the TypeNote icon in your menu bar, select a score from the library, and grant Input Monitoring permission. Then press any key — each keystroke plays the next note in sequence. Eight demo scores are included.
TypeNote is free for macOS 14 Sonoma and later. No account. No subscription. Your keyboard has been waiting.
