For instance I have a Sonitus Wah wah on a track and I have learnt the "wah pedal" and also the High freq for the wah. So now I have two distinct sets of values sitting on the track. I can ATM affect the High value, but the wah values are darkened and unatainable.
 
How do I switch?
 
Thanks for any help

S'OK I found them,,but I will have to practice to remember how to delve down there. :)
