Updated firmware success! Used command line mdfwupdate.exe megadrum1284_56_20210520.bin. Tried MegaDrum Manager FX for firmware upgrade but did not work for me. Greatly appreciate all the help.
I have a 56 input Atmega 644 unit. Firmware is 20111006, 20MHz. I can’t seem to update to the latest found firmware for that unit, 20140809. I tried through the MegaDrumManagerFX. I cant download the older MegaDrumManager either. Do you have a solution?
