What are the differences between CTRL/Slider protocol and MIDI CC?

Question

Hello there,
recently I've purchased a korg nanokontrol and I've entered the mysterious world of CTRL/Slider protocol
As I am sure many of you know you can apply to the controller in question logic templates and usb drivers, or install the device directly in logic.. and boom the new CTRL/Slider option shows up in the control surfaces set up window.
I've not really fully understood what it does.
If you let your set up use it instead of your traditional midi ports, then the controller will control logic faders BUT will not send CC midi messages anymore, thus beacoming useless to control 3rd party virtual instruments.
Conversely a korg editor let you fiddle with what appear to be CCs but still, if logic is set up with CTRL and Slider as input and output ports, no joy with virtual instruments.
Am I misisng something or CTRL/Slider and 'traditional' Midi are mutually esclusive?
all the best

As soon as a control message is remapped to a *Controller Assignment,* that message is not sent to Logics' sequencer anymore. Which makes sense, because the controller would otherwise affect two parameters simultaneously, and that would make it almost useless, or you would need to configure extra (MIDI CC)filters.
And since you can remap that controller message to any automatable parameter in any plugin +and to+ any mixer parameter and almost all key commands, there really is no need to want to use MIDI CC for any of that.
...unless you have a third party plugin that has no or few automatable parameters, and can only be controlled by MIDI CC ( RealGuitar being an example).
How your controller specificly interacts (with its plugin and all) I don't know, but the principle that a MIDI control message remapped to track automation will no longer 'get to' Logics' sequencer applies anyway.
