Hello
Which audio interface has lower latency...
Babyface Pro FS or RME Fireface UCX II
I need short latency (6ms) for VSTI.
My VSTI: Pianoteq 8, VIlabs TrueKeys and Ravenscroft 275, NI Komplete 12, etc.
Thanks for tips
greeting
Both interface use the same driver, there is no difference to expect.
The computer itself should be able to play those software-instruments, then the interface will serve you.
The biggest latency comes from the software-instrument itself, the interface can't compensate this.
6ms should be no problem for both interface.
Usually, you only have the half of RTL when playing VSTi, all drivers / RME interfaces should do.
You should be able to use an ASIO buffer size of up to 128 (maybe even 256) samples at single speed (44.1/48 kHz).
Some RTL values from Windows:

So you should concentrate more on the feature set that you require.
You can use my Excel for an overview:

When using UCX II you can also use the new features like Room EQ and Crossfeed and you have a full implementation of FX chip. Other features: more powerful headphone outputs, DURec (for standalone and backup recordings), Autoset, more I/O in general.
As waedi already wrote, I also think the specifications (and maybe optimisation) of your computer are much more important.
I can easily play software percussion instruments on my old Macbook (2012!), using a Babyface pro and a Malletkat MIDI controller. Buffer size 128.

Sorry, doesn't want to be too picky here, but regarding the initial question about latency:
CPU performance doesn't change things like RTL, this is static / predetermined by driver, sample rate, buffer size.
Of course, it is important to have the CPU power to process VST/VSTi in time.
Best low DPC latencies to have an agile system (with good drivers not allocating / blocking CPU cores for too long).
If the CPU power is not sufficient, you can try to freeze some VSTi tracks.

Do you want to play these software-instruments live ? ( I did assume this )
Do you hear a delay ?
Do you wish to get help to reduce this ?
What computer is this ? Windows or Mac ?
Both will get you easily below 6ms.

1. Do you want to play these software-instruments live ? ( I did assume this )
2. Do you hear a delay ?
3. Do you wish to get help to reduce this?
4. What computer is this ? Windows or Mac ?
1. Yes. Only two piano tracks at the same time
2. I feel the Latenc up to 6ms
3. The keyboard response is faster and more pleasant to play with low latency. I play VSTI live. I hear and feel differences ap to 6ms, unter 6 ms, i feel good . Yes, yes, I know that there are statements that you can't hear anything under 10 ms, but that's bullshit, smart shooter claim. And my ears aren't the best. I like reduce the latenc to minimum
in my laptop
4. My laptop with: Windows 10 with Cubase 12
Latency is highly dependent on the system. I once got Windows 7 running under 3ms on a laptop years ago. Without any audio interfaces. Directly via audio input. Today I cannot operate my PC with Win 7 due to a lack of drivers.
I have i 9 13900K processor with MSI MEG Z790 ACE MAX Manboard with 64GB DDR5 RAM. and Schenellsten M.2 running with Hammerfall HDSP AIO.
Cubase 12 configuration without dropouts Live only with 2 piano tracks at the same time at 128, 48kHz at 7.5ms latency... That's very critical for me. I can play, but playing the piano is more comfortable under 6ms.
Now I want to make my laptop faster with Win 11 than it is currently.
I stopped turning off the services... Because then Win10 was no longer stable. You could do this very well under Win7 and it also helped bring the latency to 50%.
I'm now trying to make my Win11 laptop faster. Current Focusrite Scarlet 18i8 gen 2 have 9.2ms latency... A real "struggle" for me... The new audio interface should bring me under 6ms
A sensible reduction in latency by switching off the services might still be possible. Unfortunately the high latenc comes from ACPI and unfortunately you can't switch it off on a laptop... I've already followed countless instructions without any useful results and always ended with a reinstallation of Windows.
If you have useful tips, I can implement them.

Hallo Mirek
Thanks for these deep answers.
You are fine by requesting lower latency than 6ms, I know Jazz drummers who complain 3 ms.
Babyface or UCX ll ?
Can you effort the UCX and may need the extra inputs and outputs one day ? Then the UCX ll is the real deal.
Otherwise the Babyface Pro FS is a quantum leap and you will be happy. May you can find a music shop who borrow you a Babyface for a test ? Try before buy... (and let us know how the latency has changed)
For the Windows, the experts will help you.
Hallo Mirek

Hi
Quantum leap, in which meadow?
Quantum leap from Scarlett to Babyface
The latency, the driver, the overall handling of audio with Totalmix

Ah ok
My question was; Do I have more advantages with Babyface Pro FS than with Fireface UCX II or the other way around?
The UCX II has the more complete feature set and also got some features of the flagship interfaces UFX II and III.
Autoset, DURec, Display, Mic Preamps with a gain range of 75 dB, full implementation of FX chip, stronger phone outputs.
It has WC (word clock), which you should have just in case you need to connect a preamp without digital input (to receive clock signal). More I/O ports and more variety in terms of types of ports. More analog I/O ports make it easier to integrate e.g., external FX, be it Lexicon PCM reverb unit or what not. Then also the new features Room EQ and Crossfeed.

The Babyface is designed to be a mobile interface which can also be operated with USB bus power.
Therefore, it has some limitations and not all features like UCX II or the flagship interfaces.
A disadvantage can be the cabling on the desk if you plug all cables on all three sided.
So if mobility is not your 1st priority or "must have", then the UCX II is the more complete offering port and feature wise.
You can use my Excel comparison sheet to compare the interfaces.

Ok. Thanks all User here
