Reverse engineering: Arturia minilab 3 firmware

I poke around a firmware update file for a USB MIDI controller, the Arturia Minilab 3. The goal of this video is to show some tools and methods I use when first looking at a firmware image.

Some segments have horrible audio for some unknown reason, and the volume is all over the place. My brain can barely handle analyzing firmware while trying to explain, let alone speaking clearly and coherently...
