For PC EQ there are 2 ways (only, and the first one in case that is not XL version):
1) ACT. You can use "ACT MIDI" plug-in for that.
Pros:
* easy to setup
* CakeWalk standard tools
* you can control other modules / FXes / VSTi
Cons:
* ACT mapping "drive some people crazy..." (the subject of one recent thread in Sonar board)
* EQ should be in focus. You can not control it when some other plug-in is in focus, after focusing different strip you need manually focus its EQ
* there will be no light from LEDs
2) My plug-in (see the signature).
Pros:
* can "follow" focused strip and "find" its EQ. So you are always controlling EQ in parallel with other FX/VSTi in focus (in one mode, strip and ACT can also be configured).
* can be configured to control several EQs/Comps in parallel
* LEDs can show valuable information (band enable for example)
Cons:
* hard to configure initially (I can help since the protocol documentation is available)
* closed source, "one man made" tool
For ready to use with ProChannel solutions, assuming you are not against option number 2, have a look at BCR2000 instead:
* endless encoders with ring indication
* can do much more than just PC/ACT
But since you have nanoKontrol and Faderport you probably already know about my plug-in capabilities
