Hello dears this is my first topic here… I hope someone could help me…
I have a Roland D50 connected to my PC via midi <> usb interface…
When I try to do a bulk load, it shows midi communication error immediately I start the D50 librarian to send the sysex file… I have already tried many of the tips available in the net…
On the other hand, sending a bulk dump from D50 to PC works fine…
Might it be a hardware issue? Or, could someone give me any tip?
Thanks!
Happy new year
Hello Alessandro,
The D-50 has two Bulk Load modes, the normal one that works from a D-50 to another and a Sysex mode that you can access doing this:
1- PRESS “DATA TRANSFER”
2- WHILE YOU ARE PRESSING “DATA TRANSFER” PRESS “ENTER”
in the top right corner you should read “[Bulk Dump .O]”, press “ENTER” again and then send the Sysex Message!
I don’t know if you already followed this procedure but it’s something that not much people know.
Let me know! 
Have a good day!
