FAQ
Do I need a MIDI keyboard?
No โ the on-screen keyboard works too. With a real MIDI keyboard it's more fun and you also train hand-eye coordination.
Which browsers are supported?
For MIDI input you need a browser with Web MIDI support: Chrome, Edge, Opera, Brave. Firefox supports MIDI only with limitations. Without MIDI it works in any modern browser.
Is my data stored?
Only locally in your browser (localStorage) โ settings and best times. There is no server, no tracking, no signup.
Does it work on mobile?
Yes, the app is responsive. For longer practice sessions a larger screen is more comfortable.
