Hi Matthias, I've tried two things. The first is to monitor the dump from Midi-OX (with midi cables connected both ways). I can see the sysex packets coming in. I don't believe there's any return messages from Midi-OX. This was the setup that took 3 mins for a 2 sec loop to dump. The other thing I've tried is from Cakewalk. Cakewalk has an "initiate dump on device" mode. This is for when you don't know the request string. Cakewalk waits until the device starts sending and grabs the sysex packets as they come in. I suspect there's nothing sent back to the sender, but I'm not really sure. Cakewalk shows a running byte count. The count was zero even with the dump running on the EDP. This works fine with an AN1X. There's one other thing I'd like to try. Cakewalk will send a request string. This requires adding the device-specific request string to a special file. If you can let me know the sysex string to request a dump from the EDP I'll give that a try.
