Applying LFO to velocity?
 

Maybe I'm asking to much here, but is it possible to adjust the LFO rate with velocity? I.e. the harder I press the key the faster the LFO, the softer, the lower.

Mod Matrix: "Velo On" (source) > "LFO1 Rate" (destination)

Or you can use LFO2 Rate / LFO3 Rate too.

Increase the intensity accordingly depending on how much of an effect you require.
