Hi all,
so far thanks all for your suggestions. I tried to get Midi-Ox to write a log, but failed miserably. No idea if it's me, but nothing that was received ended up in the log, no matter the settings.
Anyway, yesterday I tried to just dump the DX7 to the TX7 and that worked, the TX7 received and understood the dump.

but first try Bome's Send SX because it's simpler, with much less of a learning curve:
This one actually showed data when dumping (see attached). As suspected, the sysex-terminating 0xF7 was not included. So that fits with my guess that the DX7 is original from autumn 1983. As you can also see in the attached dump, the DX7 keeps sending 0x43 after ending the dump. This is almost exactly described in So, in that respect, sorry to have bothered you. It's just that before Bome, I didn't see any sensible data on my computer.
So I guess part of the problem is that the MIDI stack expects well-formed MIDI and especially the Web MIDI API does not relay data that it doesn't understand. Quite a shame, I had hoped that I could do my MIDI stuff with that, but I'll always have to some raw receiver to verify the data.
So, I was barking up the wrong tree, the DX7 was not (well...) to blame, it worked exactly to spec. Great to know.
Again: thanks!
Cheers, Florian
