ok Rory i've been all the afternoon on this!
i think that the midi DATA automation contains all the info about the parameters, while the MSB automation kind of activates them?
I think that to make it work i have to go and just touch with the mouse the MSB curve automation...and i dont know why! maybe Live doesnt read that curve until i touch it? crazy....
May i know on which daw are you using Guru?
Anyway i think that's kind of solved...somehow
