How to create an autogapper?

hi, i’m wondering how to create an autogapper using an analog filter + LFO and sync it up to LPB & pattern length?
I had a legacy method of creating it, but the parameters have changed so i don’t know what that is anymore.
is there a doofer example somewhere maybe?

I’m not exactly sure what an “autogapper” is… Is it like a trance gate, where there’s a tempo-synced LFO controlling the volume or filter?

Yup thats what it is
Ill check 2.8 renoise to see what it looks like and what it sounds like, hopefully then be able to redo the logic
