Eurorack parasitic voltage

Hello! I’m newbie in gen~, daisy and DSP.
I have version and daisy patch and this trouble:

I need that information is written to the buffer only when I rotate the controller.
I realise it this way.


Everything works fine in max, but it doesn’t work in the module. Not in Patch, not in versio. If I understood correctly, that works some parasitic interferes in eurorack, from which the voltage changes slightly and the “change” is triggered.
Maybe there are options to set some kind of range, filter out parasitic changes or achieve something similar in another way?
Thank you for your help!
