Default Cube Automatic Piano Four Keys
Default Cube’s bizarre “Automatic Piano” is a quirky, chaotic creation with just four keys, unlike the standard 88-key piano. Designed to maximize frustration, it shifts its keys around every time you try to play a note, making it nearly impossible to complete a song.



There’s no technical breakdown on how it was built, but this one-off creation appears to use a mix of mechanical and possibly electronic components to achieve the key-shifting chaos. Can someone create their own version? Yes, but not without lots of trial and error.

You’ll need a basic keyboard frame, stripped down to four keys, a mechanism to move or reassign the keys’ functions (could be mechanical like shifting levers or electronic with programmable MIDI triggers), and some coding or circuitry to randomize or shuffle the key outputs after each press.
