Default Re: -Help- Pro Tools is recording late

What is "SF" in "UA Apollo Duo SF" Mk I or II? Firewire? Thunderbolt?

(edit April 2023: ouch deleted incorrect info that has been sitting here for years)

ADC corrects plugin latencies, it should not affect anything you are seeing where there are no plugins.

There will always be convertor delays adding some latencies... that will be corrected by Pro Tools regardless of the ADC setting.

All versions of Pro Tools correct for recording latencies... Pro Tools Ultimate/Standard/Studio/Artist/Intro... they correct according to the latency reported by the CoreAudio or ASIO interface when using non-DigiLink interfaces. Or I should say "should correct for recording latency" since there is the known bug where checking "ignore errors" causes incorrect time line placement of recordings (with or without "ADC" being enabled).

There are also a known bug with H/W inserts that can cause very large (2K or 4K or so samples) false incorrect ADC corrections if they are used with Low Latency Monitoring. While Pro Tools latency and ADC is a buggy mess, it is usually possible to get stuff working OK if you avoid the known problems.

Do you have "extra buffering" disabled in the the UAD console? Make sure ignore errors is not checked in Pro Tools.
