Control only the software instrument of one channel strip at a time with one Controller

Question

Hi people,
I have a Nord Lead 2 and a Korg Nanokontrol and I want to use these as Midi controllers in the following way, but don't really know how to set up the system:
I have 4 Channelstrips and each has the free software instrument Tyrell N6 inserted. I have the opportunity to change the volume of each channel strip with my faders on the Nanokontrol which works fine and gives me the opportunity to make layers and change also to only use one sound at a time. And this works fine. However, now I want to have the opportunity to change the parameters of each Tyrell with my Nord Lead. But with 4 channelstrips each with a Tyrell N6 I want to have the opportunity to only somehow manipulate only one instance of Tyrell at a time and change the channelstrip for which the Nord Lead manipulates the Tyrell. Is there an opportunity in Mainstage to do that?
Hope it is understandable. Help would be really much appricated. Looking forward to hearing from you.

Hi DaCaptain,
Thank you very much for your answer. I tried it yesterday, but it doesnt really work for me to be honest. The thing is that I really wanna stick to one patch, so that I can have like one patch for each song.
However, if you might be interested I found a way to do it yesterday on my own. This is how I have done it:
In Layout-Mode
- Create Controls for each instance of Tyrell. For my purpose I created 4 times:
             - controlls for the Filter Section
             - controls for ADSR1
             - controls for ADSR2
- So you have 4 Sections of controllers in Layout Mode. Each meant to controll one Tyrell Instance
- Now each section gets its own Midi Channel. So all the controllers of section 1 respond to MIDI Channel 1 and the controllers of section 2 respond to MIDI Channel 2 and so on. 
- Now you tell the Nord Lead that it should send via MIDI Channel 1 and you assign the Cutoff-Controller of the Nord Lead to the controller (the one of the first section) that is suppose to control the cutoff of the first Tyrell. And you proceed this way until all the controllers of the first sections are assigned. Then you swith to MIDI Channel 2 on the Nord Lead and assign the Cutoff-Controller of the Nord Lead to the controller (the one of the second section) that is suppose to control the cutoff of the second Tyrell. And here again you proceed this way until all the controllers of the second sections are assigned. Then you go on with the third and fourth section taking MIDI Channel 3 and 4.
In Edit-Mode
- In Edit Mode now you of course assign the controllers to the functions in each Tyrell
Result
- Now you can switch between the MIDI Channels on the Nord Lead. This is quiet easy because you can assign a MIDI Channel to one of four buttons on the Nord Lead.
- So if you switch to MIDI Channel 1 you can controll the functions of the first Tyrell and if you switch to MIDI Channel 2 you can controll the functions of the second Tyrell. And all in one Patch with only one controller which is even from the nineties. I find this really great. The only problem is that the Layout might get really messy, if you try to maybe control more functions of each Tyrell. And I really think maybe Mainstage in future could give us the opportunity to create bigger Layouts - maybe with different Windows or something.
Hope you might find this interesting or even helpful.
See you
