Why do you/they need more than one .OCX?
If all it needs to do is to feed arrays to VFP then one OCX with the interface raising one event should be enough....
>What would work is if there was a way for the VB ActiveX control to directly call methods on the VFP form. Then the controls could simply pass they parameter arrays directly to the VFP form.

They could do it indirectly by raising an event that passed the method name as a parameter.
