My engineer has the Protools HDX setup and has almost no latency with massive sessions, he probably uses more or the same about of FX plugins as me on a 12 core mac from 2012. I’ve been using a Mbox mini 3 and Scarlet 2i2 for the longest time, but once sessions begin to grow I can’t run sessions lower than 1024 buffer rate without pops. Asio gaurd is worse when engaged.
Specs:
Windows 7 Ultimate
DAW: Cubase 8 (newest update) and Vienna Ensemble Pro 5
CPU: 3930k
RAM: 64gb 1600mz
Motherboard: GA x79 UD5
HD: 10 SATA 3 SSDs for samples, 1 for OS and DAW. Mostly 840 Pros and 850 Evos.
PSU: 1500W
The most intense libraries were in my sata 3 ports, the rest sata 2. However I upgraded to a LSI adapter, now all my SSDs are sata 3 through my PCIe lane, and my OS drive remains in my motherboard SATA bay. That has only helped with load times or drop outs. I have also tried using multiple VE Pros with less instruments.
My question is - How do I get low latency with big sessions? Is there something like the HDX box for Cubase or do I just need an internal RME or UAD soundcard? Maybe I need a slave? I know theoretically a better sound card should only matter while recording, but this is kind of pathetic for my setup. I don’t think upgrading to the newest Chipset will matter, since my Sandy Bridge Enthusiast rig is very good.
One thing I can point out that helped tremendously - I now mix exclusively in VE Pro, disabling all outputs to Cubase except like 10 outputs, so I can modulate certain synths and instruments.
Yes internal RME! Not UAD. UAD is great but not for low latency. I can run my larger sessions on 128 and asioguard even helps then. But my large sessions might be small for you or the other way round. What kind of CPU load (not asio) do you see in task manager when you run such a session? One of the big advantages of RME is that it allows higher cpu load at low buffer settings then the competition and that the buffer settings are true not triple buffers as with some other cards. So even 256 and 512 are playable, but 512 is on the edge. Piano, orchestral are etc fine drums and percussion a little difficult.
Mbox and scarlet are AFAIK very bad for low latency.
I’m around 30-40% in task manager, leaning more towards 30 most times. Ve-Pro is never higher than 70% cpu, switching from 4 to 1 buffer does not help much.
Can you recommend a good cost efficient RME? One that can compete or be better than the HDX. Something basic, I only need to record 1-2 instruments max, main priority here is latency.
If you have a PCI slot second hand hdsp9632 are really cheap. For PCIe it is the HDSPe AIO.
Also a multiface with a hdsp (PCI) or hdspe (PCIe) card will do. Also RME usb and firewire drivers are really good so any of those.
But… better then HDX? RME does not do any processing. Only asio is done in hardware hence the low load of the driver.
And again but,If you only see 30% on the cpu that gives good hope that RME will make a lot of difference. But what is your total CPU load cubase and VEpro included? If that is about 90% or even higher RME might give you somewhat lower latency like 256. But it is difficult to predict without testing it.
Also performance is worse on a mac the on windows with the same hardware. My good experience with RME is on windows not mac (no experience).
Cheers!
256 is good enough for me. Pretty sure I have one PCI port left, the HDSP 9632 should be good. Doesn’t the multi face defeat the whole purpose of internal and no firewire? Here’s one:
The problem buying second hand is some are hot and unregistered, just like LSI adapters. Is HDX the pro when it comes to latency there’s nothing upper tier as good and expensive?
I’m supposed to include vepro as well? I thought task manager was an over all representation of cpu usage.
Yes it is overall! But you mentioned 30% and then 70% for VEpro or is that 70% what VEpro says?
If 30% is overall you can run even lower then 256
hot and unregistered???
Ah wait intel macs running OSX never had PCI slots (only powerpc did). So you either don’t have PCI but PCIe or a hackingtosh. RME never made pci card drivers for OSX since they never existed. So you would if I am correct need a PCIe AIO.
VePro stays at 70% max. Task manager is always around 30%, while vepro is at 70%.
I have a macbook pro for travelling, my main rig is PC, I updated the specs in my OP. I’m going to test this RME and see how it goes! I should also update to Vienna Ensemble 6 eventually for performance boost.
One more question before I buy, at the bottom left of my board near the PCI lanes, the last lane looks different and backwards, would this PCI RME fit? This is the only lane accessible, my GPU is a monster and is furthest from my PSU.
I thought so thanks! I’m reading that the drivers are going to be outdated soon, and that there’s lower latency with PCIe vs PCI. HDSPe AIO is my next cheapest option?
Meh I can always get a PCIe adapter for my next motherboard.
So here’s the combo:
I already have a RCA to quarter inch cable.
I’ll be paying around $350US for both items, with no warranty, or returns (like most these ebay ads). I can get it brand new at sweet water for $530US. Might be a good ieda to just fork over another $200 for security.
Also, pretty sure this PCI version on ebay is not carried anymore, here is a newer versions:
Lower latency on PCIe is not true. Maybe with above 100 Channels. I have not seen anything about the drivers stopping development. HDSP and hdspe is one driver. I am pretty active on the rme forum.
Yeah the 200 extra might be worth it. I got my SH cards much cheaper, but in Holland from a site called marktplaats. Not international (though owned by ebay)
The hdsp9652 is an adat card only. no audio outs. I have that one too. same generation as hdsp9632.
The second one is a digiface/multiface adapter card, so no audio card at all but for their break out cards.
Price is OK. Here a little cheaper but not that much. Thing is PCI is dying and not on new motherboards any more. Therefore they should be cheap I think. They can be made to work on PCIe if needed with an adapter board but it is a DIY project and not pretty. Thing is I can only be sure that they work great here. So the cheaper the better. If it doesn’t work out for you it would be nice if you can sell it without loss.
If possible ask the seller for the revision of the card, some older revisions don’t start on the newer motherboards and need a modification.
To bad things are never easy in computer world.
Wow looks like Startek are the only ones making PCIe adapters. I was hoping for a company like Sonnet or OWC.
What do you mean by revision, firmware upgrade?
The unstable and unpredictable PCI adapters are kind of a deal breaker, I assumed there would be higher end ones available. I might try to talk them down to 200. This is kind of a bandage upgrade for now, I plan on a new chipset early next year. By then I may want thunderbolt over PCIe.
Any other internal soundcards you can recommend? 246buffer would be good enough.
Sorry I was wrong! That is for the HDSP card not the HDSP9632! So no worries.
The startek do work I heard. Maybe the cheap ebay ones too. As long as they have a power connector.
