> 1.  filters like the 420/440/480 CAN mix CV signals?

Only on the CV ("FM") side. You *cannot* pass CVs *through* the filter (kind of 
difficult with integrators).

> 2.  the motm-110 vca can NOT mix/process CV signals?

Well, it's AC coupled. You need a MOTM-190 for a DC coupled VCA.

Also note: both the MOTM-830 and MOTM-890 Mixers are DC coupled.
