Create beautiful interaction with sensors and sound.

Bela is a maker platform for creating beautiful interaction.

Designed for artists, musicians, researchers and makers, Bela brings the power of ultra-low latency interactive audio and sensors to your digital projects.



We are constantly developing and expanding our product line to meet the needs of makers and creators everywhere. Along with our Bela and Bela Mini, we offer a number of accessories and add-ons to give you the functionality you need to bring your projects to life.


Trill Touch Sensors

Trill is a family of touch sensors that was inspired by the way musicians use their hands to interact with the world. Compatible with Bela as well as platforms like Arduino, Teensy and Raspberry Pi, Trill sensors use capacitive sensing to precisely track finger movements and positions. Trill sensors were funded on Kickstarter and are available now. Click below to find out more.



Built for speed.

Bela uses Xenomai Linux for hard real-time audio processing with latencies as low as 100us, a speed that even the best laptop can’t match.

Code, your way.

Code in C/C++, Puredata, Supercollider, or a variety of other languages. Use the in-browser IDE for C/C++ or your own environment. You develop it, Bela runs it.

Connect everything.

Bela provides stereo audio along with 8 channels each of 16-bit analog I/O and 16 channels of digital I/O, all of which are sampled together at audio rates.

Open source.

Bela’s hardware and software are both open source, and Bela benefits from the innovation and support of its worldwide community of musicians, designers, makers and tinkerers.

Fits almost anywhere.

Bela is powerful, but small enough to fit almost anywhere. Run Bela from an external battery and embed into instruments, interactive objects, effects boxes and more - no laptop required.

Browser-based IDE.

Bela features a browser-based IDE, with full C/C++ development capabilities. Includes powerful features at your fingertips, such as an in-browser oscilloscope, code examples, and much more.


Gliss is an elegant and intuitive synthesizer module for touch control which is now live on Crowd Supply. This Eurorack (4HP) module lets you draw waveforms directly into your system so you can add a human touch to your control signals.


Resources to learn and create

Bela's hardware and software are open source, with contributions from our community around the world. Musicians, artists, tinkerers, designers, and makers of all kinds are using Bela, and we support this community with an active user forum, a blog featuring projects made with Bela, guides to help you get started, and more.
