Just want to caution that in my experience Ansible (mine was bought new from monome mid last year) uses the at32uc3b0512 chip, which has more flash than the at32uc3b0256, and I believe this backup procedure did not back up the presets from flash unless I used the
dfu-programmer at32uc3b0512 read > firmware-backup.hex
command listed under the Teletype instructions. If you want to try out a new firmware and then go back to the saved Ansible presets you had, I think you might be unpleasantly surprised when using the at32uc3b0256 command.
