For this project I din't want a complicated circuit. There's no negative power supply, everything runs on DC power from an external block. Many options are available on the board for changing parts.

There's a UART interface to debug via Serial interface. Never done that, could be fun !  and also a great help for reading live data. However there's only one UART on the processor so it means the MIDI should be shut down when using the UART interface com.

Also, the ADC and DAC can be changed for higher resolution ones from Microchip as their chips have the same pinouts.

I added test point to not poke around on the parts.

More to come I guess...
