Generally speaking I don't know anything that controls the ProChannel except the eq which is in the first position.
You can control other ProChannel modules as well, just not all of them. As was pointed out in another thread, if you click on a control and there are little white "corners" around the controls, you can control it. Otherwise you can't. Ones you can control include the EQ, PC4K S-Type Channel Compressor, PC4K S-Type Bus Compressor, PC76 U-Type Compressor, Concrete Limiter, Bus Compressor, U76 Compressor, and PC4K Expander/Gate.
I guess the modules you mention are old "Filter" replacements. I think the whole idea to derive ProChannel from Filters has many problems. Following "filter logic", there can be only one EQ, Comp., Gate., and Sat. In the "filters" they had to be in specific order. The possibility to move them around as well as completely different types of modules has introduced complete mess in that "filter logic". It simply does not "fit" well. It looks like CW developers has tried to make "something working" for V-Studio and only for it.
There may be more, but I know these ones work with the V-Studio, which is based on the Mackie Control.
V-Studio, Mackie Control, StudioMix, etc. (all of them!) have simple logic. They just deliver "Note On/Off" "CC change", "PB change" or "NRPN change" to the software. What make them "support ProChannel" or anything else is the plug-in.
Mackie Control plug-in is completely different from V-Studio one. MC plug-in is older, not ProChannel aware and has plug-ins parameters specification in INI file. V-Studio is newer, knows about ProChannel and has known plug-ins parameter specification hardcoded (!) into the source.
