I found the problem! It’s because I wanted to get fancy and model the output stage of my real S&H, and that produces an output voltage drop. I will remove that feature since it does not seem to add any advantage in the Rack world where all the voltages are perfect.
@Yeager Thank you for reporting it!
Thanks for finding the “problem”, 
I hope no one is relying on, or extensively using this “feature” 
You never know. Probably someone will write me an email telling me that Leakage now is so life-less 
Oh man, I’m happy that it worked fine in the video 
UPDATE : version 1.4.0 of Vult’s modules solved the issue.
Thank you Leonardo.
Leonardo,
It seems like Leakage is only generating and passing positive signals now. Is anyone else having this problem or am I doing something wrong?
Yes. Sorry about that. In my previous fix I inserted this new problem. Never work after 3 AM on code
I will fix it in my next release very soon.
