Just a note on QoP sample switching. The SD card is on the back of the unit, so you have to remove your module to get at it, so this is not the kind of module for regular sample switching. ...

I wonder how badly things would go if one were to use a little ribbon cable extender to break out backside microsd slots to a 1-2hp module with a frontside slot or two (or three? however many fit i guess)

Something like https://www.amazon.com/Chenyang-Memory-Female-Extension-Extender/dp/B07QXPG8HG ought to be a decent test if somebody wants to do some science...

Edit: probably worth noting though, modules with backside slots likely don't expect card hotswaps!
