A falling-notes practice tool for the accordion, in the spirit of Synthesia. Open a MIDI file and the notes of both hands fall onto the buttons or keys you play them with: the treble on a C-system or B-system (bayan) button board or a piano keyboard, the bass on the Stradella board.

Connect an electronic accordion such as a Roland V-Accordion over USB, and the app reads what you play:
No MIDI needed: follow the falling notes on any acoustic accordion, button or piano. You can also press the buttons and keys with the mouse.
When a song's treble part goes lower than you want to play with the right hand (a piano part, say), click a lane where the notes fall:
Space plays and pauses, Home goes back to the start (or the loop's start), ← → move by bars and ↑ ↓ change the speed by 5%.
"Open the sample song" on the first screen opens Greensleeves to try it out.
Connect the USB COMPUTER port and the input is picked up automatically. To hear songs on the instrument's own sounds, set MIDI → Ext Seq → Accordion to On on the instrument, and choose "MIDI: Roland Arranger" as the track's sound.
On Android, connect through a USB OTG adapter or a USB-C to USB-B cable, and set the instrument's USB driver to Generic ([MENU] → System → USB Drv, then save with [MENU/WRITE] → SYSTEM and turn the instrument off and on). If the device only says it's charging, restart it with the instrument connected.
Songs play through SpessaSynth with the GeneralUser GS SoundFont bundled (Italian Accordion by default).
