The front panel menu system: Global->About->BSP-> Linux 4.9.47-rt37 2019-12-20.C23818C Granted, I cannot prove that because it says the above that it's really running Linux, but I'd guess it is. > Also, do you know which microprocessor(s)/FPGA(s) the Plethora X5 uses? > No idea at this time. Also no idea about A/D & D/A. In my mind the unit is essentially a 1 channel DAW that can handle 5 plugins as well as an insert bus that can be put anywhere in the chain. Running plugin modules, be they LADSPA or whatever is more or less how I see the design. > I'm partly asking because I wonder if the X5 might be able to run > software from Mod Devices or vice versa.

Dropping a firmware update into that window and power cycling does the firmware upgrade automatically. <SNIP> A first response from TC Electronic via a moderator named 'TC-Mike' is that the ability to backup the device is 'on the roadmap'. I asked about general timeframe but have received no response. Cheers, Mark
