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. The Arduino sketch can be found on this page: Arduino sampling tutorial on which this is based:
