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:
- compatibility with the Teensy board (with the exporter)
- testing outside the board (with the online tools)
- 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.
