Hi Martin,
absolutely, this is a good idea! I am always worried with new releases of Windows / macOS that something might break.
You will find all of Thorsten’s sources in the MIOS32 github repository:
https://github.com/midibox/mios32/tree/master/tools/mios_studio
Whatever is going on to update the firmware is not magic, so it will be possible to write a shell/script tool for it, but it still will require some work.
An idea: we will release a new eurorack module soon and when the external flash tool fully works on all platforms (Windows/MacOS/Linux) with hopefully minimal dependencies we’d send you one of those for free (covering shipping, but not possible customs taxes/fees) as an implementation thank-you.
Thanks for investigating this!
Best regards and have a good sunday!
Peter
