Hi, I am on Windows 10 latest version, the computer is a 9900k with 64gb (Gigabyte z390 Aorus Pro), AMD video Card.
Drivers are 4.36 and upgraded firmware after installation, it says version 20 and up to date.

Sorry for that, it is 20H2. Thanks in advance for looking into this!

Hi Ramses,
They are the same projects, same computer, just disconnected the MOTU, fully uninstalled drivers (also in hidden drivers in device manager), installed AIO PRO, new drivers, new firmware.

Opened cubase, load project, same sample rate (48k)

Regarding latency, since I uninstalled the motu I cannot measure it.
AIO PRO At 4096 buffer, Cubase is reporting 85ms in, 86 out, (170 asio guard).

But I remember that the MOTU was managable at 1024, I could play VSTIs without much delay, that´s not possible with the AIO at 4096. At 2048 AIO gives lots of dropouts.

I have read about safety buffers with USB, but Motu at 1024 should be roughly the same to AIO at 2048?

There must be something I am doing wrong, because I have only read succesful cases of composers running similar projects with similar computers and no hiccups, I went with PCIe and not a babyface because of all the recommendations.

About the headphones, I now it is possible but there must be something I could do, I have dissabled c states in the BIOS, and changed the computer outlet socket and it helped a little. I have read that I can shield the bracket with tape so it doesn´t make contact with the chassis.

Again thanks for your help!

Some information about your system would be helpful.

PC or Laptop ? Which CPU, Mainboard, how many DRAM, HD or SSD ?

I am wondering that you need such high ASIO buffer size values...
I am also using some VST and VSTi but usually can use buffersize values between 32 and 256.
In rare cases, when having a very bad VST, the maximum that I needed was 512.

And even with many tracks (400) and many VSTs enabled (~800) I have no audio drops at ASIO buffersizes
of only 32 samples and sample rates of single or double speed up to 96 kHz and no matter whether using
RayDAT (PCIe) or UFX+ (USB3), see here:
https://www.tonstudio-forum.de/blog/ind … cks-de-en/

And yes, if you select such high ASIO buffersize of 2048 or 4096 then the latency is that much.
But I am not sure about 4096 whether this is available for single speed.

Can it be the case that you run the project at double speed (88.2/96 kHz), because then the buffersizes
are double compared to single speed, that would explain the 4096.
But it could also be the case that the HDSPe driver has a higher maximum value at single speed.

How high are
- CPU load and
- your ASIO load
when playing back such a project ?

Are you running at high performance energy profile ?

How is your DPC latency on an IDLE system ? You can make measurements with the Tool LatencyMon.
Search the forum, several checks have been made already.
If you make this measurement please take care to do this on a freshly booted system, just logged in,
waiting until all processes are started up, then start latencymon for at least 10min.
On an IDLE system, please no keyboard activity or mouse movement, this Test creates a typical DAW load on its own.

> way less Vst than 800.
Could you kindly be more specific, way less is no number ...

> could it be the VEP extra buffer making some problems
I have no experience with such an environment, sorry.
What means on two extra computers ? Can you pls explain the signal flow ?
Does it mean that two extra computer are there as VEP7 "number crunchers" and that there is an instant communication between your main machine running the DAW and those 2 VEP7 computers ? Sorry, but you need to explain this to me a bit more ...

Otherwise .. .make a check .. similar project, do not use VEP, does it make a difference ?

Hint: if something does not work as expected, try to change 1 parameter and/or simplify to be able to catch the root cause ...

Does turning off Wifi make a difference ? We will see what LatencyMOn will report.

Don't hurry ..

Sorry, image quality is too low, if you export JPEG, please check that export happens with 100% Quality.
Otherwise its much likely that one can't read text, etc ...

Please also copy/paste

Thanks.

Well if Vienna runs as plugin / insert.
Then IMHO the same is applicable as for all other VST inserts.
Your Machine needs to process all inserts in such a track one by one.
You have the processing "outsourced" to two other remote machines, so the one or the other needs the time to
- get data over network
- process audio
- send audio back
Instead of the local processing you have on top the overhead of the remote connection.

I hope you have the network access through a LAN cable.
Wifi would be counter productive, because WiFi does not perform bidirection data communication.
It can only one talker send and receive.
Depending on the WLAN standards and whether you have consumer or enterprise equipment this can be better or worse.

Best is to have at least a gigabit connection to a network switch and a good card.
But all accesses to the network also create IRQs .. this increases slightly
- Interrupt Rate
- DPC processing
I am not sure whether Vienna also supports Jumbo frames.

You need also to check all network connections, whether you have good cables and no network errors.
All needs to be set to 1 Gbps and FULL-DUPLEX operation.
Just in case one link would communicate in half-duplex for whatever reason (misconfiguration, mix of auto and static speed and duplex settings) the network performance would go down.
Watch for CRC errors and speed/duplex settings on all active ports.

And .. do not use WLAN for such a processing ....

Is it ok to put the video card in the 8x slot and the RME in a 1x slot?

Very valid point. Or USB is connected to chipset and has no issues on the way "north" to CPU
if he used before USB ports that came from chipset ....

Thanks for the help, sadly returning it is very difficult because a a courier brought it from abroad and it would be almost impossible. not mentioning that UFX would be a lot more expensive, very sad that it can´t work as intended

I will try the sound card in the other slots to see what happens

Ramses do you need the latency mon data? I have ran it for 20 min

oh dear

I have an i9 10850k on a z590 board. Am I going to run into this PCI lane sharing issue too (when I finally solve my cable access problem)? If so, that might be the final straw. If it only works well on super computers, it’s no good to me.

Actually, this "should" also run with your computer. But a PC is complex and technology can sometimes be a real bitch.

As a normal mortal here you can actually no longer know what you still have to pay attention to everything to get a working computer for audio.
OK, there are some avoidance strategies to stay on the winning track if possible, but you really don't know until you test out the finished solution.

I heard from an acquaintance that the somewhat larger system houses in this area even get special customized BIOS versions from Supermicro, for example. Whether this is really true or just clever "marketing bla bla", I can't say. But I take it from the people that they have put in a lot of work to deliver a really smooth-running system.

Either you are lucky and make a golden strike or you learn it the hard way (what works and what doesn't work). That's why there's no shame in buying a turnkey system for audio. Preferably from people who really know what they're doing.

For me as a hobby user with semi-professional ambitions, it's easier, I have no project pressure at all. But if you live on it, I probably wouldn't hesitate to get something tested. You'll recoup the price by not wasting time on tinkering or money on new or additional purchases.

I have tried a single kontakt with the giant on it, it doesn´t play with a buffer below 512...no sound at 256, 128, etc.

That can´t be right, there is something more at play than pci lanes here

I have the latency mon images you requested, how can I upload them here for easy viewing?

ok, I took out video cards, working with the onboard graphics (can´t use it because I need several screens), the only non motherboard device on pci is the AIO card

nothing improved, so I don´t think it is pci lanes related, something else is wrong here, but I don´t know what else to do

Hello, everyone!

@Pablo1980
What other devices do you have connected to the AIO Pro? Are they properly synced?
Also, how many WDM Devices do you have configured, in the RME Driver Settings?

Another tweak, you can make, is to optimize Windows for 'Background Tasks'

Ah, nice!

Can you set WDM Devices to "0", so that you will have only ASIO operation and check if the situation improves?
(You 'll loose Windows audio, but it's good for troubleshooting. You can re-enable them, later )

Ok!

Also, try a test @44.1 KHz, if it's not too much of a hastle!

Hi

Just to mention it I'm a Windows 10 Cubase Pro 11 user and had the RME AIO for a long time and was rock solid allowing me working at even 64 samples buffer.
I switched to the new AIO Pro as soon as I saw it and my Cubase performance has decreased a lot,but I can still work at 256/512 samples so no big deal for me.

So I believe that something's going on with this new card and Cubase Pro 11.
Maybe it requires some driver/flash improvement.

Just my two cents.
