Granted, I cannot prove that because it says the above that it's really
running Linux, but I'd guess it is.
I purchased [a TC Electronic Plethora X5]. It
works well (so far).
It's Linux internally running 4.9.47-rt37.
I'm curious: how do you know which kernel your Plethora X5 uses?
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. Mod Devices makes ARM-based
multi-FX guitar pedals that run Linux: akin to the X5 but using
LADSPA/LV2 plugins instead of TonePrint ones: https://moddevices.com
Finally, do you know if TC Electronic has published any of the source
code relevant to the Plethora X5?

I haven't looked hard for any of that but I also haven't seen it in the
manual or on their website.

If you plug the Plethora X5 into a Linux box via USB,
how does it
present itself to the host?
# Run this on your GNU/Linux box with the X5 not connected:
lsusb --tree > /tmp/lsusb_x5_disconnected.txt
# Run this on your GNU/Linux with your X5 powered up and connected
# to it via USB but everything else the same as above:
lsusb --tree > /tmp/lsusb_x5_connected.txt
# Copy the output of this command and paste it into a reply to this

In Windows when you plug the device in your get a explorer window. Dropping
a firmware update into that window and power cycling does the firmware
upgrade automatically.

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,
