You're barking up the wrong tree trying to fix sync issues after the fact. Assuming you're using your interface's zero-latency monitoring correctly, the real problem is more likely due to incorrect latency
compensation.
A DAW needs to know what the latency is so that it can line up the takes correctly after recording them. Sometimes, the interface doesn't give it the right correction value and you have to set a manual offset so that everything comes out properly lined up.
Somebody once posted a good step-by-step procedure for setting the manual offset. Try googling "site:forum.cakewalk.com manual offset". If you can't find it, check back here and I can describe the process.
