I've been using synthtribe 2.4.9 to update the firmware on all my behringer gear.   Worked great on the Ms1, the RD8, the tb3, and the pro1.  My VC340 is "in dfu mode" and the app continually asks me to update the firmware.  When I click update, it says "update failed, please try again."  All the lights on the vocoder are on and no sound is coming out when keys are pressed.  I am using mac with the latest edition of Big Sur.  I have tried rebooting the computer, getting rid of all hubs and peripherals, with no luck.  I have submitted a ticket but I am concerned.  Anyone have any ideas?
