PT11 - UAD2 problems

[YYR123]

Nice info Dan, hopefully they won't cause a big problem I haven't seen the live button so I will have to look

(Newcomer to the UAD format)

Thanks again

It is the little microphone on the lower left of the plugin window. When clicked it turns red. Sometimes for drum sessions, I will cheat a bit and use the EMT140 plate reverb in "live" mode while tracking.

First off - I'm a huge UAD fan owning 2 Octos. They are a big part of my mix. That said - I consider this to be a bug (and poor design also counts as a bug).

I've been reading about the 1024/1088 sample delay in AAX64 for months, but I've never seen a reason (technical or otherwise) as to why UAD have chosen to add this delay. If they could code the RTAS version to provide snappy response, why would they keep themselves in worst offender position with a crazy per plug buffer. I could get behind a single 1024 buffer per track (regardless of the number of UAD plugs used) if there was some good reason for it.

I also don't accept that using an Apollo is UAD's solution for this. I have a HDX system and an Apollo just doesn't fit. I'm maxing out 16000+ delay limit due to UAD's Native long buffer plugs on HDX SubGroups (HDX design issue).

Frankly - this seems like madness. UAD - FIX THIS!

Is there a way to optimize the card so that the UAD plugs cause less latency?

Shouldn't Pro tools delay compensate everything ? I think I might be getting some shift due to this issue

Avid threw UA a curveball with their new dual buffers in PT11. Great for regular native plugs, but BAD for UA.

Currently, for whatever reason, UA's plugs use Avid's fixed plugin buffer which is 1024 or 2048 depending on sample rate. There's also the issue of delay getting stacked that didn't happen in 10.

UA needs to figure this all out and have said that they are looking into it.

If they can make their plugs switch between Avid's input buffer on armed tracks and the plugin buffer for everything else, this combined with UA's "Live Mode" and we could be in business. Until then, this is it.

UA's plugs in PT have always been pretty much "mix only" due to the latency of the cards/boxes.

Thanks, Drew. Comforting to know that there is mindshare on this at UAD.

There are several former Avid people at UA now one of which is the architect of AAX. Here's hoping he can work some magic. :)

Here is something I do not understand, maybe someone can explain this.
Isn't the whole reason to have a dedicated DSP card so that you wouldn't have latency natively and tax the system?
I love UAD, let me repeat LOVE UAD Plug ins but I would think that there should be near zero latency in Protools when using a third party dsp card. On top of it UA can record at near zero on the Apollo why is that not working on their cards?
I am really confused about that...

Preach brother !!!! While they are recoding stuff - go ahead and fine tune the plugs to use less DSP while your at it......

There's really no way this can happen with current tech from what I understand. The audio has to go out to the UAD and back to the DAW. Every plugin you add in series is another trip the same channel has to make to the card and back. It's different from the way a TDM or HDX system works where the mixer and the plugins (provided they are not native) are on the same cards. It's IMO the only real downside to the UAD.
