blackcom, it does appear that you can only send midi in one direction. I would use the real midi connectors on the breakout and leave the midi over madi unused. RME is squeezing a lot down that madi cable... I love my madi card. It just works. I have been using the breakout since day one and it has always been flawless. It would be so cool if you could use the full capability of your interface and get bi-directional midi, as having things in a machine room can create serious logistical problems, and long midi runs can be problematic. If you need to run long midi cables through walls or under the floor, you can use in wall certified DMX 512 cable. It's 5 conductor with a shield, and has good bandwidth for midi data.
Matthias, you are really abrasive every time you talk to customers. Why? We are the people who pay your wages. Don't you get that just because someone has a question about your product,doesn't mean that they are A) stupid, or B) trying to downplay how great RME's products are? THEY JUST HAVE A QUESTION. Every post I read from you is unprofessional and I don't understand. You are pretty much the face of RME on this forum and you are detracting from the credibility of your company. Yes you know a lot, but you don't have to be condescending every time you share your knowledge.
