Questions from a prospective user w/Pro Toos 7

[BezO]

A few questions:

• Can anyone using Pro Tools 7 confirm good performance from the UAD plugs? I haven't been able to confirm that the UAD stuff has been updated for Pro Tools 7.
  [/*:m:1xfv9lzi]
• Being that I will need the RTAS Wrapper, can anyone give me an idea how bad the latency issues will be and how you're dealing with them?
  [/*:m:1xfv9lzi]
• My understanding is that the plugs run exclusively off the DSP Cards. Is that the case? Absolutely no CPU usage at all?[/*:m:1xfv9lzi]

I'm strongly considering the Studio Pack. I've heard these plugs and in action and I'm sold. If it weren't for a few functional concerns, it would be bought already.

Thanks for all responses!

  I can confirm. I've got 2 UAD-1 and PT LE 7.0 (win).
  No issues at all with pt7.

  [*]Being that I will need the RTAS Wrapper, can anyone give me an idea how bad the latency issues will be and how you're dealing with them?

  You need the wrapper. In the next weeks Fxpansion will releeas the new
  versione of the wrapper optimized for pt7
  
  There are no latecy problems caused by the wrapper.
  
  Of course UAD plug-in cause latency (2 x buffer size) and PT LE DO NOT
  compensate for that delay. S
  o you have to learn how to use the Delay compensator plug-in included in the Uad-1 and how to set up your mixes to avoid sync problems (i.e. with
  sends)
  
  at the beginning you'll hate PT. but, belive me, the workaround is
  easy and not a big time consumer.
  
  search the forum for some tips&tricks about delay compensation with pt le. then, if you need more help, you can find me here.

there is some cpu usage, of course, but is very small and is not caused
by the plug-in processing.

also the wrapper use some cpu.

I think that 2 cards are better than one, because when UAD-1 cpu goes
over 90% you'll see a big increase of PC cpu usage.

with 2 cards you can make \"big\" and smooth mixes.

Thanks. I wish you were on a MAC for a more direct comparison, but if the plugs are PT7 friendly on one system...

That's the other thing delaying my purchase.

There are no latecy problems caused by the wrapper.

That's right. I meant the extra CPU usage by the wrapper.

Of course UAD plug-in cause latency (2 x buffer size) and PT LE DO NOT compensate for that delay. So you have to learn how to use the Delay compensator plug-in included in the Uad-1 and how to set up your mixes to avoid sync problems (i.e. with sends)

I had planned to simply shift the actual audio tracks instead of using the delay compensator, and keep track of how much shifting I've done. But I'm sure I'll get some good advice on what's best.

Sends to the delay compensator? I was inquiring about that, but I would have to dedicate a few buses for routing them. I'd rather reserve thos buses for other things.

search the forum for some tips&tricks about delay compensation with pt le. then, if you need more help, you can find me here.

I tried some searches before I made the post but didn't see many PT related posts. I figured not many people here use UAD=1 plugs with PT because they're natively VST.

But the search timed out on me a few times as well.

I think that 2 cards are better than one, because when UAD-1 cpu goes over 90% you'll see a big increase of PC cpu usage.

with 2 cards you can make "big" and smooth mixes.

Oh. So the plugins run on the DSP card up to a certain point, and then begin to use the CPU? Or is it that the more the plugs use the cards, the more the cards use the CPU?

Is there some documentation that explains how this works in detail?

Hi Bezo,
sorry for being a win user, I did't that your message was in the Mac section.

Sends to the delay compensator? I was inquiring about that, but I would have to dedicate a few buses for routing them. I'd rather reserve thos buses for other things.

I don't mean \"send to the delay copensator\"!
I mean that: you have your drum tracks and you whant to add some reverb
(using sends) and also you want to add compression.
when you put a uad-1 plug-in on a track you get a delay the output.
imagine you use a send and an aux track as return fot your reverb.
ok...now a little numeric example

you've got a snare track, without uad-1 plugins
snare -> out: delay= 0

you use your send to an aux. on this aux you put your plate 140:
aux return-> plate 140 -> out: delay = 1024

as you can see...reverb and snare are NOT in sync. reverb will play
1024 samples later.

if you put a dealy compensator on the snare track you'll move forward also the signal going out form the send so the reverb will still play
1024 samples later.

the solution is to add an aux track, to buss your snare to that track
(usually you'll buss all your drum tracks) and to put the delay compensator on the new aux.

snare -> out: delay= 0 -> buss to an aux
aux -> delay compensator -> out: delay 1024
aux return-> plate 140 -> out: delay = 1024

Of course you can nudge your traks instead of put delay compensators.
I don't like nudging very much.


About how to use delay compensator plugins, I'm quite sure that in this
forum there is a post I have made, some months ago.

Oh. So the plugins run on the DSP card up to a certain point, and then begin to use the CPU? Or is it that the more the plugs use the cards, the more the cards use the CPU?

No. Plug-ins do never use the cpu. But there's some cpu usage due to, I think, the data running form the sequencer to the uad-1 and back.
I think that the increase of cpu usage you get at certain point is related
to \"hardware and software communication\".
If I've understood right, every time you put a uad plug-in on a track,
you audio data travel from seqencer to uad and back.
1 plug-in = 1 travel, 2 plug-ins= 2 travels, and so on...
I'm quite sure that your computer cpu has to manage all these data exchanges.

Is there some documentation that explains how this works in detail?

I don't know.
