MidiFlow Piano

MidiFlow Piano turns your iPhone into a real-time MIDI practice companion. Connect your digital piano or MIDI keyboard via Bluetooth and play along to any MIDI file — with instant feedback on every note.

HOW IT WORKS

• Import any MIDI file from Files, Safari, or share it directly from another app

• Connect your MIDI keyboard via Bluetooth (BLE-MIDI)

• Watch notes fall towards the keyboard in real time

• Play along and get immediate feedback on accuracy

YOUR MIDI, YOUR MUSIC

MidiFlow Piano works with any MIDI file you already have. There are no locked libraries, no subscriptions for content, and no limitations on what you can play. The built-in library includes a curated selection of public domain classical pieces to get you started.

DESIGNED FOR PLAYERS, NOT BEGINNERS

MidiFlow Piano is built for pianists who already know their way around a keyboard and want a modern, mobile-native tool to practice with. If you've used Synthesia on desktop and wished it worked better on your phone — this is for you.

PRIVACY

MidiFlow Piano collects no data whatsoever. Everything stays on your device.

REQUIREMENTS

• A MIDI keyboard or digital piano with Bluetooth MIDI (BLE-MIDI) support
