Are you using the trigger input?

No, only MIDI ?

That's wierd. Did the Xpander use to respond to AT and then suddendly stopped, or did it *never* show any response to AT?

If it's the former, I would seek the culprit in the transmitting part... something got blocked or filtered.

If it's the latter... well, it's been long ago, but I remember the Xpander undergoing a major software update a few years after its introduction. It could be that the very first version didn't respond to AT.... I can't be sure though.

Btw, I would make sure to enable CONTROLLERS for the Zone you're using, and for the Zones at the MASTER level. Just in case.

I guess I find it !

My Xpander has the oldest firmware.
"2. Previously, when using a synthesizer with channel pressure, (the new DX7 software for example) ,
the pressure would be ignored if the Zone Input was set to OMNI. To use the pressure with the old
software the Zone Input had to be set to channel 1. This problem has been corrected in version 1.1."

Yes, changing the Zones to MIDI channel 1 solved the issue.
