About Tokyo BLOCKS Hackathon


BLOCKS is a new hardware music environment developed by ROLI, allowing to create new music gestures and practices. BLOCKS can be entirely customised and assembled with Max, Javascript, C++, to develop interactive experiences for desktop, mobile and web. The hackathon will bring together artists, developers, designers and product visionaries to create unique creative experiences.


Over two days, team up with designers, developers or artists to invent interactive experiences. Everyone is invited to join the hackathon: from students to experienced developers, designers , artists and musicians. It is the perfect place to build and test ideas. You can either bring an ongoing project or start one from scratch, use the technologies available and join a project!


The hackathon takes place at the fantastic Google’s office at Roppongi Hills Mori Tower. We will offer great prizes to the best teams. You will also get to meet artists and engineers that will guide you and give you feedback on your projects.

What is BLOCKS?

BLOCKS is an ensemble of hardware tools that connect together to allow to customise your musical creations. BLOCKS works as a usual MIDI controller, but can also be customised. BLOCKS is used by artists all over the world to perform and compose.

How does it work?

One the first day, after the presentation of the technologies, we will invite you to form small groups of 3-4 people (typically 1 engineer, 1 tester, 1 designer, 1 musician), to work on a project of your choice. The goal is to develop a project over 24 hours that you will present at the end of the event. This project is not restricted to the technologies we present, it can be anything you want to do! You can build a musical instrument, a game, a light installation or a music remote control. We will present to you software technology (Javascript, C++, Max), but you can use other technologies or hardware. As part of a team, you will brainstorm ideas and share the tasks to come up with a fun idea to present. Download Blocks Dashboard to start building programs for Blocks.

Here are two examples of projects built during a hackathon at ROLI:

To join a team, you can be a musician or music producer, an artist working with interactive technologies, a software or web developer, a designer, a product manager, or someone curious to learn new things and willing to work as part of a team. Please bring your personal computer with you!
