Stand-alone “mod” idea with raspberry pi and surge xt – Roger Linn Design Forum

I am trying to figure it out if it would be possible to create a (battery powered) raspberry pi unit, booting directly with surge Xt standalone, connected to Linnstrument via USB or CME so I could basically use it as a standalone unit.

On Surge XT’s github page it says that it is possible to compile Surge XT on a 64 bit Raspberry Pi.

My concerns:
– Connection with Linnstrument and MPE using cable and or CME to the Raspberry Pi
– Audio Quality
– Battery power for the Raspberry Pi.
– A script or control solution for the parameters of Surge directly from the Linnstrument.

Has anyone managed to pulled off something similar? if yes, please share your process and experience.
What do you all think?
