I found a few USB / MIDI 'libraries' for STM32.
However, I'm looking for a library that can handle (multiple) MIDI In/Out (DIN5) connectors with STM32 (preferably STM32F4), thus using UART/USART.
I wonder if something is available (to prevent creating it myself while something similar exists), since I cannot imagine I'm the first one doing something with MIDI (DIN5) ports.
I'm looking for something similar as the Fourtyseven Effects MIDI library like on the Arduino: fourtyseven effects.
