The J-Play app goes Open Source

The company closed, but the mission continues. We're open-sourcing the J-Play app and donating instruments to schools and therapy centers—ensuring accessible music-making lives on.

The J-Play Story

Our mission was simple: make music accessible to everyone. No need for years of music theory, no need to be tech-savvy. Just the desire to express yourself, create, and feel.

J-Play was born from a vision to create a digital musical instrument accessible to all. An intuitive interface, colorful design, and unparalleled expressiveness thanks to its interchangeable silicone pads.

This vision touched thousands of people: children and adults discovering the joy of composing, music therapists finding new pathways to their patients, music schools reinventing training

why open source today?

The company closed its doors, but J-Play instruments are still out there in homes, schools, and therapy centers. By making the software open source, we ensure that these instruments remain functional and can continue to evolve.

Open source means the J-Play community can maintain the app, fix bugs, add features, and adapt it to new operating systems.

⚠️ note for macOS users

The macOS application is not digitally signed (signing requires an Apple Developer account at $99/year). When you first launch the app, macOS will block it. To run it anyway:

  1. Right-click (or Control-click) on the J-Play app
  2. Select "Open" from the menu
  3. Click "Open" again in the security dialog
  4. The app will now run normally

Alternatively, go to System Preferences > Security & Privacy and click "Open Anyway" when prompted.

⚠️ note for Windows users

The Windows application is not digitally signed (signing requires a code signing certificate). When you first launch the app, Windows Defender SmartScreen will show a warning. To run it anyway:

  1. Click on "More info" in the SmartScreen dialog
  2. Click "Run anyway"
  3. The app will now launch normally
⚠️ note about iPad

The iPad version is not yet available as compilation requires paying Apple (developer license). If the community wishes to fund this version, we could make it together.

instrument donation program

The donation program is complete: all the remaining J-Play instruments have been donated.

✅ thank you

The J-Play instruments left after Joué closed have been given free of charge to music schools, colleges, libraries, music therapy centers and medical and social organizations.

Thank you to everyone who applied, and to the teams who now play these instruments with children, students and patients.

We have no instruments left to give, so the request form is closed.
