Latency with UAD plugins much higher than in Ableton

If I use a UAD plugin like LA-2A on an audio track while recording there is a 23.8ms. This is large enough to be noticeable when recording.

Weirdly, I've moved to Logic from Ableton, and I never noticed this issue before, so just did a test and in Ableton the latency for the same plugin in 3.8ms. Why is there such a huge difference?

This means that I can't use most UAD plugins for recording, which seems ridiculous when it's fine in other DAWs, and is part of the sound.

Yes I know I can record through the UAD console, but I usually mix UAD and native plugins so I can't do that, and as I say this was never an issue in Ableton.

Is there anything I can do about this?

(I've read all the usual articles/posts about buffer size and latency but none that I can see cover this particular issue.)

Yes, both are using AU plugins, and the sample rate is the same for both projects (48k). As far as I can tell everything else is the same, buffer size etc.

But I really never had any issue in Ableton which is why this is so puzzling.

I've just discovered LiveTrack which alleviates the issue to some extent, but I don't really want to have to use it as it uses a lot of CPU and I have to remember to switch it on/off..

Cheers,

Mike

Just to be sure. Are you sure you compare with the exact same plugin? AU vs AU and not AU vs VST?

As you said there are many factors involved in latency. Did you test with different settings? Even the sampling frequency has an impact.
