After a few Weeks of hard Work and Troubleshooting (Thank´s TK) my Midibox is finally Running.
My Design is a little bit customize for the Switches.I use the Digitast from Reichelt! The Response with these types of Switches is great, an she have the LED integrated)
The Frontpanel is not the Final one. But it was an good Idea to reqalize this from a 2,5 mm Cardboard. It covers me for a big trouble with the gaps of the Switches.

4x Midi Out + 2x Midi In ( 1x Midi In-Out via USB connected on J11 )
