Plugdata is a rabbit hole, but thankfully you only need to learn a few dozen of the most common objects to start making things. It took me a week of low effort learning before I could make patches without needing tutorials or outside help. The built-in documentation is all you need after that.
Does that plugin have a distinct sound you like? To be honest I've never moved beyond my DAW's stock eq and compressor. And god, iLok is a scourge.
