I'm having a bit of a curly one at the moment. I recently purchased a parallel MOTU Midi Express XT to expand my midi setup from one port to eight. It is attached to a 1.2Ghz AMD with 512MB RAM running Logic Audio Silver 3.5.
Attached to the MX XT are a Yamaha EX5R, Kurzweil PX1000, Yamaha TX81Z, Yamaha DMP11, Akai S950 and an Alesis Midiverb 2 and a Roland D10 temporarily acting as ( don't laugh) master keyboard.
My problem is the EX5R does not receive midi data while attached directly into the MX XT (everything else works). I have swapped to known working ports, used known working cables and nothing works.
However, when I connect the EX5R to the through port PX1000 I can see data and everything works....
