WARNING:
The current diagram of microDRUM is not compatible with the Arduino DUE. Even the code is not compatible because of the different processor.
I made the changes on a micro-microDRUM and seems to work. I will try to see if it can use the DAC to generate usable sounds, only if I can make it work I will share changes to the schema and code.
