Massage or message If message, all MIDI communication doesn't work
Isn't it just problem of some setting MIDI channel, filter or  
similar Or hardware - bad cable, MIDI interface...

message..
no,,

Have you tried some reset or test mode There must be something like  
this...

i am not familiar with that

If nothing helps, it's time to open it, check cables and connectors,  
reseat them, also chips in socket (if any), and check the way of MIDI  
signal. Maybe optoisolator on the input is dead, or some other  
component.

ok..
