Reply to VCI-100SE FW1.4: Play on button release?

Hey team, I'm getting settled in with my 1.4FW upgraded VCI, and I'm finding that accuracy is an issue. When I hit play, it never seems to be right on the beat. I can't tell if it's latency or my own inaccuracy. I thought I'd try and remedy the issue by setting the play button to play on release.

Are there any benefits to doing this? Is it even possible to do this?

Thanks for your help!
