2 days ago I bought the Behringer Ultracurve Pro used. I'll start by saying that it was working perfectly but I wanted to update it to firmware version 1.4 (currently 1.3 was installed) so I searched the internet for version 1.4 .syx and tried to load it via a midi interface (cme u6 midi pro) the loading was not successful. I lost the old version and now I can no longer use the Behringer. I tried using a PC with Windows XP then using Ubuntu then using Windows 10/11. I changed the various delay and buffer size settings on Midi Ox but nothing worked. Can anyone help me?
