I'll start with a project by my friends: FXcursion is an STM32-based guitar processor prototype. It has 3 stereo inputs and outputs, builtin effects chain, looper and recording. It lacks proper user interface (we've found a designer last week, so it's in the works now!), and the hardware still needs a lot of changes, but I've been impressed with the progress so far. https://github.com/RATsynthesizers/FXcursion https://github.com/RATsynthesizers/FXcursion
