DMC Micro is a really good approach to get the most from the C4 without going full on-MIDI. If you already have a MIDI controller, then the Hub is fine.
I purchased one when using the Enzo but returned it at the same time... I'm also thinking about diving in further and replacing my current fuzz with an Aftershock, is the Mini still a good idea with two SA pedals or would a more advanced controller be a good idea?
I'm def no filter expert. But I do know when one sounds awesome and it just works. The Meatball preset @nnavarro made on the C4 is stellar IMO. It sounds the way a bass filter should sound. And it's simple and very effective. I love it. But again, not a filter expert. I just know when it sounds good. And there are two or three community presets that sounded straight awesome to me out of the box.
Is that preset in the demo video he put on YouTube? Checking it now...
