Could you build this?
Partial Writing standard chord logic is easy, but real-time embedded firmware on ESP32/Cardputer handling low-latency BLE, USB MIDI, and hardware DIN output requires embedded C++ and RTOS tuning.
What it would actually take: The project runs on the ESP32-based M5Stack Cardputer using the ESP-IDF or Arduino framework in C++. The complex parts are handling tight real-time MIDI clock synchronization, BLE MIDI stack latency, and low-level GPIO/UART timing for DIN MIDI alongside keyboard scanning. It requires embedded systems firmware development skills and physical testing hardware.
