Pianocade – Chiptunes synthesizer and MIDI controller

The Pianocade is a synthesizer designed to sound, look, and feel like vintage arcade games. It’s easy for people who want to dive right in, powerful and feature-rich for people who want to tinker, and fun to play for everyone.

With synthesis hardware based off of classic gaming systems and a 128-note range, the Pianocade lets you perform the retro sounds you want, live.

With traditional 5-pin MIDI and USB MIDI, you can use the Pianocade to control other instruments, or use external sequencers and controllers to play the Pianocade.

Program the the sounds, customize the controls, decorate the case, hack the electronics. Make your Pianocade your Pianocade!

Open source
All of the Pianocade hardware, firmware, and software is open source and designed for easy hackability. If you’re really ambitious, build your own!
