Load ps 20 and do the patching as shown in the screenshot .
This routes the output of osc 2 into the esp , and ouput of esp in the lowpass filter freq .
This gives us filter FM ,the eg2/patch panel knob now defines the filter fm amount ( and overrides eg 2) .
Now restart ps 20 , and do the exact same thing ..there is no more filter fm ....it seems that the esp signal module is not working anymore
Also the vu meter is not moving anymore

Some more in detail
First patch + screenshot + audio

Filter fm is provided by noise
Second patch , after reloading (identical patch settings ) , notice there is NO more filter fm from the noise osc

Or even simpler
Load the synth and the patch 'slow down from the bass categorie ,modulation is done by vco 2 --->lpf and high pass f.
Reload synth and same pacth . totally different , the modulation is absent .
