Hi there,
More than likely the timing has just jumped due to your processor being loaded down when you click the "I Like it Let's proceed to saving it" button. This shouldn't affect the final mix. When the preview light is green the preview is accurate. If that light has jumped to red or yellow it's not accurate.
You can remix your saved songs. If you click on the Account tab and then on Recordings in the sub menu you'll see a list of all your recordings. To remix a song click on the edit button for that song. Once on the edit page you'll have the option to remix.

so rob does that mean when the light is green we should click like and save then instead of letting it continue? or can it get out of sync even so?

The light itself actually has nothing to do with the final sync. The only thing you want to make sure you do is adjust the sync based on what you hear while the light is green. In other words don't adjust sync when the light it red or yellow. If the light drifts some it won't change the sync setting when saved.

Hello Rob, I'm having the same problem but no matter what I do it gets out of sync. When it gets to about 2 thirds through the song.

That sounds like a dropout issue. Check out our FAQ about this issue. If the info there doesn't help send us a message in support and we'll continue troubleshooting. You can message support from the "Contact Us" link at the bottom of any SingSnap page.
Can you explain why I get "Dropout Detected" and why the sync gets gradually worse?

Why, when I listen to my FINAL take, does it fall out of sync when I click OK? Also, WHY can't we keep our vocal track and remix instead of having to retake, or am I missing something?
I like singing here, but the mixing controls need to be beefed up a tad to make it a bit more friendly.
I just wonder if I'm the only one with this gripe?
Take care and keep up with the great sounds everyone.
