In the old days, a MIDI interface had connecting ports into which you  
had to insert MIDI cables. Those ports were labelled MIDI IN and MIDI  
OUT. When connecting to another device with identically named MIDI  
ports, the rule was that you connected IN to OUT and OUT to IN. That  
way, data would flow out of the OUT port and into the IN port.

In more recent times, most USB MIDI interfaces have had the MIDI  
cables hardwired to the interface. The MIDI plugs at the ends of the  
cables are usually labeled IN and OUT. Unfortunately, some  
manufacturers have used those labels to indicate the direction of the  
data flow while others have used those labels to indicate the ports to  
which they should be connected.

So, the modern rule is this: If it doesn't work one way, connect them  
the other way.
