Please make tutorial for Refer / Link Object Parameter to widgets

[Seekingseek]

Wanted to link a Ty parameter to a slider widget. But It seems, that is only to link to a MIDI or OSC. Would be really nice, to get the option, to link for example the Ty, Tx or Tz parameter of objects to the perform section.

Would be possible to get deeper Tutorials for using refer / link in Automation Editor, Graph I/O and Perform section?
Especially for linking inner modules together. For example: Slider to Ty Parameter of an object or Automation Editor Keyframes link to a perform button. Something like that, would be really great :)

Thank you in advance.
