I think the site answers this issue Andy...

The stie says that the 12bit DACs give 1/32 semitone resolution, while the 
8 bit DACs give 1/2 semitone resolution. I would suspect that anyone firing 
a CC at the MCV 24 may notice the staircasing that is bound to occur.

The MCV 24 page itself point this out...

   (in talking about CV4-CV24)

   " that jobs like glide/portamento or LFO modulations are not
   possible due to the rough resolution."

Given that Tony gave a quote of more text than is on the page that you're 
looking at, I might suggest that he's looking a different page than you 
are; or maybe his local cache isn't refreshed.

I'd like to point out that Tony mention other MIDI->CV convertors than his 
own in his message. Quite professional of him... Unlike some folks that 
seem to be jumping a bit quick to attack him.

My take on this is that Tony is speaking from the point of view of someone 
designing MIDI->CV convertors. I would figure that if he (or Kyle or 
Kenton) thought that they could get away with 8 bit DACs then they would of.
