With Dimension Pro running as a VST, are those two parameters exposed?
Both versions of Dimension Pro expose those parameters for automation, Mark. Vector Desaccel as well (akin to the Smoothing parameter in the Matrix). In the DXi version, the Vector X and Vector Y are right at the top of the 'widget' list. In the VSTi, you have to burrow down into the list of available parameters. Look just above that cluster of "Reserved" parameters. It'll read slightly differently (depending on what's been already assigned), but they're in the row that starts with Element Pan 04 - Reserved.
[by default, with Project5 as host].
In your other hosts, I wonder if you couldn't get the ball rolling by enabing a Write operation, and then just using the Vector Mixer GUI itself to generate some automation curves as a "location device". You might be able to find them easier that way. Hey, there could be a problem with how a host handles the automation parameters, too. All are not created equal. and sometimes certain synths or plugin versions exhibit some quirky behavior.
Like z3ta+. I never use the DXi for automation,; only the VSTi. I even had a little problem with researching this answer using VSTi DimPro and P5 V2. Once, it seems like I had to 'jump start' the Vector axes to get them to write
automation. But I've tried everything to reproduce that to no avail, so we'll file that under "possible user-error'. I'll bet that irritating MIDI Override button got me again.
For a good list of available Dimension Pro automatable parameters, check out the P5 Wiki

in all four areas of the MIDI Matrix.
