Ana mod wheel programming

I am having trouble getting the mod wheel to drive vibratobr
I source the mod wheel in mod 1br
target lfo 1 depthbr
turn amount up clockwisebr
I target all oscilators pitch and send a little to itbr
then I set the ratebr
the mod wheel does nothing until I dial in a little depth, and then its on all the time br
I’m sure its something obviousbr
hope that was understandablebr
cheers

On the lfo target knob turn it up very lightly maybe 1/2%br
br
It us very sensitive.
