Sax Brothers Kontakt Player CC mappings re-assigned each time re-start Mainstage

Question

Using Mainstage 2.0 with two USB MIDI devices attached:
* MIDI2USB cable connected to Korg N1 with sustain + expression pedal
* EWI USB breath controller
I use both keyboard & breath control patches as needed.
When using with Kontakt 5 player and "The Sax Brothers" plugins each time I re-start MainStage the breath control stops working on the patches. Opening up the settings for each patch, the Kontakt 5 settings, I can see the CC mapping is re-assigned
EXPRS is getting mapped to CC11, instead of CC2 ( breath controller.)
IF I reset it, it will work fine for the duration of having MainStage open, even switching back and forth between other patches. Saving the settings however, it is always getting reset.
Is there a way I can stop this remapping ocurring?
Some other points:
* When first adding the Software Instrument Track with Kontakt 5, the setting is fine. It is only after re-starting Mainstage it's not
* The default if I use Kontakt 5 standalone is to use CC2 breath controll, so suspect Mainstage is somehow changing this

Answer 1

Ok I already figured out how to do this. For those who have a similar issue:
1. Select your patch in Patch List (i.e. Alto Sax)
2. In Channel Strips select your Software Instrument Track (i.e. Kontakt 5)
3. In Software Instrument Channel Strip Inspector select MIDI Input tab
4. Change Controllers Input to Breath (2) and leave Output as Expression (11)
Saving these settings, patches now work correctly even after restarting.
