Sending SysEX?


I have connected the OPLAB to the macbook and communication seems to wrk fine. I can send and recive to Tenori-On.
I also could update the oplab with the sysex librarian.

But now I want to backup the Zoom B9.1ut. The midiwatcher says the tool is sending SysEx commands. But midiport light on the oplab is not flashing. So I assume oplab is ignoriering the SysEx commands …

… what else could be the reason, and how can I fix it?

I am in mode 3 by the way.
