Arduino MIDI synthesizer (Part 1) - Basic MIDI IN circuit
This tutorial shows the most simple MIDI-in implementation for the Arduino. The Amtel mega controller will be used as a synthesizer. It is simple monophonic saw tooth in this part as introduction but will be improved in upcoming parts. It can be easily transferred to any Atmel mega circuit.
