@elemen8t I just did this myself trying to mimic the RC-20's Intensity knob. What I ended up doing was putting each of my scriptNodeFX's inside of another wet/dry node, then when you have that done, script one slider/knob on your UI to adjust all 'GlobalMix' knobs together. So if you have a scriptnodeFX with a wet/dry setup already, put the whole thing inside of another one and let that be your 'GlobalMix' parameter. I hope I explained that well enough.
Heres a working example.
