works: MIDI-IN: code + schematics

this code:

SOMETHING ABOUT MIDI MESSAGES
 midi messages start with one status byte followed by 1 _or_ 2 data bytes, depending on the command

 example midi message: 144-36-100
   the status byte "144" tells us what to do. "144" means "note on".
   in this case the second bytes tells us which note to play (36=middle C)
   the third byte is the velocity for that note (that is how powerful the note was struck= 100)

Well, that was what I wanted to hear!!!!!!!
"http://highlyliquid.com/midi-accessories/midi-connector-inline/midi-jack-inline.jpg is the same, and the other is MIRRORED"

So we will try that :smiley:

Good luck debugging your things. If i can help(new to midi, but debugged quite a lot of other things. Robotics....

EDIT:
You saw the 36.
Strange that NO ONE mentioned it :open_mouth:
it is a darn error, I think it is THE error why people weren't getting their stuff to work!
