Hey gridlers!

I hope someone is able to help me here. I have been trying to use the randomize function on my Plonk, but can't seem to make it work.
The plan is to randomize all the parameters with every new trigger signal. (You see Andrew Huang doing it in this video:

I used the same patching as described in the manual and in the video, but it doesn't work, it only happens when I additionally press the red button.
Here's the way I patched it:
- Sequencer Gate out -> Trigger In on Plonk
- Sequencer Mod Out -> Mod In on Plonk
- Mod settings set to Randomize in Plonk

Looks like I'm missing something here, can someone point me into the right direction?
