A simple-ish digital desktop synthesizer unit, on woefully underpowered hardware.

(well it's an STM32F429, it's really just RAM-limited, but hey it only costs ~57 cad for parts + pcbs + assembly)

The project is split up into multiple subprojects, each contained in a folder. They all have READMEs related to their internal structure. User-facing documentation (i.e. a guide) is stored in the docs/ folder.

The various subprojects are:

• bmap: various resource generation tools
• board: PCB CAD files + schematic
• bootloader: The MSynth Bootloader, responsible for installation/updating/management/booting of applications and filesystem management/cleanup.
• factory: Test application for verifying board accuracy, component quality and basic unit tests.
• framework: Common code and build setup for all applications (clock setup, peripheral access code, filesystem code, etc.)
• fstool: Tools for generating and interacting with filesystem images
• app: Various primary apps are placed here. The most important one is main_app, which is the actual synthesizer core.

Note that any output of MSynth units is NOT covered by this license; you are free to do literally anything with the audio that comes out of this project, and no warranty is provided for these outputs (again, see LICENSE.txt).

Various font resources used (Lato and DejaVu Sans) are optionally used during the compilation process, but not included here; if you wish to avoid licensing restrictions you may substitute other or custom fonts with more favorable licensing.
