Yamaha DTXpress/DTXplorer/DTXtreme

Hi folks,

some time ago I was posting that I was considering to go another route
and to buy a ddrum set. Well, what shall I say I did buy and in many
ways didn´t regret. However the point is that I am now sitting with a
problem around the download / MIDI dump feature of the ddrum 4 brain
and there is nobody out there to help me.

The Yahoo ddrum forum is closed, no traffic since two years, no READ
access to their database was given.

The issue is: When I download a .mid file using the official little
ddrum software tool it is indicating that it sends files to the brain
and also the MIDI interface is indicating traffic via LED. The ddrum
brain answers immediately with an error message displaying "Err".
That´s it. No help in the manual, no forum, no FAQ on the ddrum
websites ....

Can anybody help a poor chap over the pond?

Best regards    -Bongo-
