Ah, I see. So, to summarize dozens of forum posts:

- A/D hardware on Axoloti is optimized for low-precision things like
   pots and similar sensors, so CV in requires external buffer/scaling
   and its own A/D. (For want of a proper Vref??? :( :( :(  )

- Similar situation for CV out. The audio outs are low-precision and
   are scaled for line-out levels, even though they are DC-coupled.
   So, more external hardware needed.

As for the euxoloti, it provides CV ins but outs would require another
daughterboard, still TBD.

Has anybody developed a generic CV I/O board for use with digital
beasties?

Though it sounds like, at least at the moment, the axoloti platform
lacks the software 'hooks' to talk SPI to an interface. Aaaargh.

Very interesting platform, even though it's a bit of a 'diamond
in the rough'....
