i use the same shematics, and it works.
But i spend a lot of time, searching for the reason why nothing happens: finally (Oh Lord!) i confused the direction of the midi jack! (its not easy to be supid like this...)
in this shematics, you don't see the the jack, the part on your breadboard.
its the connector, the cabel wich is shown.
perhaps this helps.
sometimes life is happy:)
