[LAU] Fixing a MIDI issues

[Julien Claassen]

Hello everyone!
   this is perghaps not straight on topic, but I couldn't find a satisfactory 
answer anywhere else.
   I'm having trouble with my JV-1080. Only every second note gets played. I 
checked different input devices and different cables, direct and indirect 
connections.
   It seems to be a problem of the Roland itself. Internal sounds, demos and 
the preview button, work fine. Any idea, what this might be? It looks so 
systematic, as if it might be by design, but I don't know any feature, which 
should allow for that.
   Sorry to spam the list and thanks for following me so far.
   Warm regards
          Julien
