SheetSnapUsing a MIDI piano keyboard in a web browser
A web MIDI keyboard connection needs a browser with Web MIDI support, a compatible connected device, HTTPS and your permission. Support differs from ordinary score playback. Try a free starter piece on your actual device before relying on MIDI grading or video export.

Check the connection before a lesson
Connect your MIDI keyboard, open SheetSnap over HTTPS and use the MIDI input controls to request permission. Chrome or Edge on desktop is a practical starting point, but a cable, adapter, driver, operating system or browser policy can still prevent detection. Importing a MIDI file is different from connecting a live MIDI device.
When Web MIDI is unavailable
Use the on-screen keyboard, listen to playback and follow the score. A mobile browser or Safari may not expose the Web MIDI API; a language or country setting cannot add that hardware capability. Check the current browser compatibility reference below. Microphone input is experimental and is not a reliable replacement for polyphonic MIDI grading.
Export and graphics are device-dependent
High-resolution video export and complex effects need more memory and graphics capacity than score reading. Try a short export, open the saved file and check picture, sound and timing before making a longer video. We do not promise 4K/60fps export on every browser or phone.
