Problem with Z3ta+ LFO assignation

It doesn't work! 

I am trying to assign a LFO to a filter cutoff, and I have trouble. I asked help on another forum, and as a test, another user made me reproduce this setup, 





And I hear no LFO modulation. Strangely, when I tweak the Offset setting, I hear the effects on the cutoff: it just moves along to the slider. But when I have to hear pure LFO mod, there is nothing. I have tried the LFO's with other parameters, and the constant is that the LFO simply does not send any modulation at all.


I tried to install the updates, but they simply refuse to open in my Albeton Live. So I'm gonna stick to version 1.5


Thank you in advance for your help.


Edit: I have tried a wealth of other tweakings,  nothing gives better result. Well, yeah, if I imagine really hard the is a mod, I can almost hear it.
