"Chopper" FX Plugin out of Timing?

I was using the “chopper” plugin today in C13 and noticed that when set to “sync” it fires a few milliseconds to early before the measure of the beat. Is this new? Has anyone else noticed this issue?

*Update

Ah, nevermind :wink: It sounds OK if you click the “mono” button.

Leaving this here for those who may search this issue, browsing clueless through this forum.
