Blackstomp is a digital audio effect processor development platform based on ESP32-A1S module. Here are some of the feature's highlights:

Stereo line or guitar input/output
Microphone input with programmable gain pre-amp
Potentiometer, switch, and button interfaces
MIDI input/output interface
WiFi and Bluetooth connectivity
24-Bit stereo codec with analog pass-through
Dual core Tensilica Xtensa LX6 240 MHz 32-bit processor with single precision FPU (floating point unit)
C++ library for fast development with Arduino IDE and ESP-IDF development tool chains.
The platform consists of hardware and software to implement digital effect pedal/stompbox. The hardware is designed for the simplicity and cost effectivity, while the software is designed to ease and speed up the application development.

This is very interesting. Thanks for posting it.

I did some ESP32 stuff using FAUST.  I didn't get very far (it seemed like the ESP32 could not do as much as a Spin FV-1 except have more delay RAM), but I put everything on Github for those inclined.  Don't read this as an indictment of the part, but just my experience with FAUST.

Regarding the Blackstomp, apparently the guy has accomplished quite a bit but I think (last time I checked) he is not divulging all of his code.

If you are still interested, maybe give the Daisy platform a go. It is Esp32 based. I have one and have coded a simple sequencer. You can make your own effects with it.

Are you sure about that?  Are we talking about this?  Says it's ST Micro ARM based.

Whoops. In my mind it was...
Anyway, it is designed to work with lots of design tools apparently. I'm using Arduino IDE but you can use PureData to "draw" code.
