UAD and Liquid Mix problem

[frankjosephs]

I have a Magma chassis (an older one with the flat grey cord) with 4 UAD cards. I recently bought Liquid Mix and added the PCI firewire card that Focurite recommends in to the Magma chassis .

My problem is that when I am using a lot of the UAD plug-ins the Focusrite craps out with a very low channel usage.

I'm wondering if an updated chassis would give me better fire power or if the problem may be elsewhere.

what kind of motherboard do you have? I would try gettng the firewire card and the LMix on another bus entirely. Does another PCI slot on your MoBo have its own bus or use a different bus than the chassis?

I'm on the same line as nightowl.
I heard from a guy in a musicstore that the Liquidmix \"eat\" bandwith on the firewirebus. So my guess is that 4 uad and one liqudmix really get the pcibus occupied. If you have a firewireport on the motherboard, try to put it there. I don't know if it share the same bus as the pci.
Or if you can buy a pci-expressfirewirecard and that way get the liquidmix on another bus. This is just a guess, and I advice you to really check it out with someone on youre musicstore.

Im also having thougths of buying new hardware soon and thought alot about how much the pcibus can take. I know that the creamwere pci-card with 15 sharkprocessors in the begining could oveload the pcibus.
But i think i've seen someones setup on this forum that has 3 uad and two powercore in one magmachassi, and that should be a lot.
And i have a frind who's got protools HD 3 in a casual pc.
But maybe protools work different. I think that the pci-cards in protools are connected by a cable and maybe they cooperate better that way.

Well just a few thoughts from me.
Is there someone who knows more about the capacity of the pcibus?

Probably shouldn't post this, as the PC version of LM is not available publicly as yet.
However, I have had the unit on test for 2 months now, and on my PC it gets better with every build.
I only run 2 UAD-1 cards, and the LM is not on a PCI firewire controller, but in series with 2 external HDD on a Mobo controller.
It's working just fine here - with both UAD-1 almost maxed out, at 44.1 and 48KHz I am still getting the full count of 32 channels on the LM unit.
Okay, at 96KHz it drops like a stone to only 8 channels.

I am assuming the poster with the problem is on a Mac?
If he is on PC, then what beta build is he running, and is the LM manager actually set to the maximum of 32 channels, because by default it is not.

4 UAD's and 3 Powercore's in my chassis, they work fine so far. Just mixed a song @ 96K with them and my only problem was native power, but that looks as if it's Nuendo's fault (~60% usage shown in the task manager, 100% in VST meter. Go figure! Nuendo would crackle, but I could load other apps at the same time - even the Windows Media Player and it'd play perfectly...)

What a wonderful setup!!!
Now i know that i most likely can add a few powercore in the future!!!!
