Dragging params to custom parameter tab

Allo allo,

I have tested it in a completely new project with just a base and a noise top inside but still, assigning does not work. When dragging a parameter from the noise to the custom param tab of his parent base i only see the arrow, no + symbol. Also copy/paste does not work.
Feels like a bug. Or is there anything else that may cause the problem?
I created a custom page first.

Thanks in advance

as I understand you want to drag an existing parameter from a node to add it as new custom parameter on a COMP? In that case you can only drop it at the “parameter” title bar:

Thanks for the reply.

I’m doing it exactly that way but no result. However, when i create one manualy i’m able to drag that one to an other base its custom tab…
