Config advice

[pieca]

Hi,

I'm considering to buy an UAD1 for my Logic rig.

This is my config :
Logic pro 7.1.1
Dual 2 Gig G5 PCI
RME HDSP 9632
In Logic my latency is set to 128

Is there any incompatibility issue with my G5?

Is the 128 latency buffer ok? (I don't want to change it, because I'm used to track even at the last step of the mix)

The main use of the card will be the La2a plug, is 20 plugs are ok on a sigle uad and Logic?

Thanks for your help.

You will have to change your buffer size between tracking and mixing (using the UAD-1 cards). I have a similar set-up, and go between 128 for tracking and 1024 for mixing. Mind you, I'm using 3 cards and a ton of UA plugs.

You can get 14 LA2As with 1 card.

Also, the 'problems' with UAD-1 cards and G5s (AMD Chipset) are well documented here. It's really not a big deal. Read more:

According to UA's specs, 20 LA-2A should be possible @ 44,1 kHz...

Thewit,

Thanks for your feedback.
The 1024 buffer setting is a big issue for me as I'm used to track even at the end of a mix and I'm using the software monitoring. I'm also using a lot of EXS and 1024 buffer setting is a too high value for me.

I've found this on the UA FAQ :
\"With Powered Plug-Ins, you can actually use small buffer sizes without reducing system performance because they use almost no host CPU power. Powered Plug-Ins bring real-time performance to your native workstation.\"
Low audio buffers seems to be OK?

14 real world LA2A seems to be really lower than the UA official specs. It may be due tou your G5 and the 75% max card load on your computer.
From the UA website, my G5 (dual 2 ghz PCI) is not concerned by this problem.

Any other users latency report?

Thanks.

20? When did they change that spec? I got 14 right off the box. Either way, remember that you will get 'slightly' less than speced with the chipset problem. Your milage will vary.

I felt the same way you did with the mix/track buffer settings. But learned that I have to lower them track and this leads to clicks and pops. Experiment for yourself, you may be doing less than I am and may get away with it.

I use a lot of UAD plugs on my busses and have to disable them or it's latency hell (PDC).

Using Logic's in the box effects you can get away with much more than the UAD-1 card.

Hi Pieca,

I have the same G5 as you have. These models don't have the amd chipset so there are no worries about any limmitation. I didn't test how many instances of which plug I can get, but the Uad behaves the same as in my pc, all pc projects open with all Uad plugs and I use a lot of them.

I work with a buffersetting of 256 when producing. You can easily work all the way to the final mix with it, as long as you bounce/record the final mix with the 1024 buffer. This is just to make sure that there are no tiny clicks/plops in your final mix. Better be save than sorry :wink:
