MICROCOSMOS
Open-Source Music Development Board

Microcosmos is a small (130X80mm) open-source electronic board, developed by Faselunare, aimed at prototyping electronic musical instruments and learning electronics, microcontroller programming and audio DSP.

Microcosmos is made on top of a Teensy 4.1 board and features several encoders, buttons, an OLED color display, SD Card, audio I/O, MIDI I/O on Mini Jack and MIDI over USBHost.

Alongside the hardware, Faselunare is developing an open-source Library to program the board. The Language of the library is C++. The official repository of the Microcosmos Library and Firmware is on: GITLAB

While FAUST is not (yet) directly integrated but must be exported for Teensy and then imported in the library, the developer team has adopted this language for the DSP part. The main reasons are:

  1. compatibility with the Teensy board (with the exporter)
  2. testing outside the board (with the online tools)
  3. rapid prototyping

The integration of FAUST and the Microcosmos is made by mapping the parameters of the exported FAUST class (called MicrocosmosDSP) using a configuration file.
The mapping becomes a way to create a multi-page menu visualised on the OLED display, where every page has four parameters that are controlled by the onboard encoders.

In this way it is very easy playing, controlling and visualising any kind of DSP produced by FAUST only by changing the imported class and the configuration file parameters.

FAQ

Can I use Microcosmos even if I'm not a developer?

Absolutely yes, you can download Programs or binaries from our website that we will make available for our community.

Which programming language do I need to know to develop my 'Programs'?

The Microcosmos firmware is essentially split into two parts. A control one, for which the Arduino / Teensy language and more generally the C++ language are used. And a part dedicated to the DSP where you can use the Audio Library of Teensy, FAUST or any language of your choice among those supported by Teensy.
