thanks again for taking time to help me !
ok writing CC in hypereditor works , i tried cc 88 , but where do you find the list ? (how did you know that cc 88 is for lfo2 to filter ?)
writing automation with soft knobs work but 3 it's not enough
record automation from sliders in the matrix page of VC doesn't work .
i still think that these limitations are weird , in all VI's it's possible to automate how much the lfo's modulate other parameters directly from logic automation instead of midi cc's ...
