To me, what you are describing sounds like an issue with the phase of the LFO. The LFO is running 8 bars, but if your audio sits on bars 5-12 the LFO will start over when the project reaches bar 9 (ran for 8 bars). In the context of the audio that's bar 5. Make sense? In the above scenario, adjusting the phase to 0 makes it match the audio. If I were to move everything earlier 1 bar (audio starts on 4) the phase would be 45.
Here's the catch (& possible bug?): If you are starting the playhead anywhere within the cycle (as if you hadn't adjusted the phase), the LFO value is what it would be if phase was set to 180 until it 'catches' a reset - I think the reset can be either of the potential LFO phases (phase @ 180 or phase @ 45 in this case). The upshot of this is if you are testing with a cycle, you don't know until the second pass where the phase of the LFO actually is, or you need to start playback a few (trial & error to see) bars back.
The retrigger & threshold might help dial things out, but I don't know about that.
worst case you can turn off the LFO cutoff mod and just automate the cutoff by hand.
Hey Seeren- thanks for the explanation. Kind of confusing, but I set the phase to 45 & selected the retrigger button...and that seemed to work.
This seems awfully high maintenance for a plug-in haha. I just don't understand why it matters where the audio in my project is. Hmmm! For this project, my audio sits on bars 28-35...and repeats a couple other times later on in the course of the song.
Thank you anyhow

It really isn't as confusing or high maintenance as it seems. Put it another way: pretend you have a piece of graph paper (that's logic's sequencer). Now starting on the left, draw an LFO wave shape that is 8 squares long and then repeats for the rest of the paper (that's the autofilter's LFO). Now take a gum wrapper and trim it to be 8 squares long (that's your region). So hopefully now you can see that if you place the region in the wrong place it won't line up with the LFO you drew. Changing the phase is like you drew the LFO on a piece of clear plastic instead of the graph paper, so you can move it left/right to align with where the region is.
The plug in doesn't know what you are going to run through it - audio from a software instrument, audio from a recording, how complex that signal is, where it starts in relation to the beginning of the region, etc.
