All good points, thanks Ramses. Also, on the other hand, if I had "UFX III with Dante", and those 12micDs, I could take them to a variety of applications whether there is need for MADI, Dante or a combination of some sorts. This would in my case be, I think, more future-proof than committing to something with say MADI only. And, as mentioned, the other benefit would be that I could use the same hardware for multiple real-world applications.

Re: UFX lll

There are maybe two things to consider. Whether you talk about MADI or DANTE or MADI and DANTE in regards to:

1. space on the back of the unit
2. more channels require bigger FPGA

Consider, that RME perhaps wants to stay with 1 RU .. so space is tight.
MADI would perhaps need to be changed to SFP.
Dante would require (I assume) 2 LAN ports (like AVB: primary, secondary)

What I want to say is. Besides price aspects there is a lot of design work to be done.
As a "quick successor" for UFX+ needed to be made available, this surely could not be done now.

And when it should come, then it would IMHO need MADI as well, so that you can re-use your existing MADI devices.

Re: UFX lll

I still would wish for something like an update to the current UFX III with two MADI buses instead of one. Maybe per SFP to get the space on the back.

Because only then you have the possibility to
- record in double speed and
- to expand analog and mic ports at the same time

For example:
- M32-Pro AD and DA (bus1) and
- two 12Mic and one XTC on (bus2)

Or two split devices to the two different buses if you want to split devices according to the remote management tool
Auxdevice and MIDI Remote.

Or you need to change the configuration / setup to use the one or other devices for higher sample rates.

Re: UFX lll

I have begun reading, with interest, the many comments in this thread.
Thank You. Sorry that it's all a problem with thunderbolt. Appreciate the guru comments!

Sorry to be posting my thoughts in fact - the UFX III is brilliant.

I hereby state:-)~>

1) there are no greater devotees than me to RME. I started back at the beginning and have never used other than RME.

2) I will be waiting for the lowest latency... AND an interface that can use nearly ALL of the CPU... UNLIKE USB which craps out the CPU way earlier than Thunderbolt.

Therefore, sadly,  I wait for a USB4/TB4 FLAGSHIP interface.

NOTE: surely the "small USB-C plug concern could be gotten around.

A specialty jack that fits USB-C in the middle and an RME special BIG plug around the the outside of it.   

Maybe like the Mic inputs that combine TRS and XLR

ALL I've thought is covered here in the thread i started.

https://forum.rme-audio.de/viewtopic.php?id=36484

Note that in the above link/thread I mention (and link to) another thread i started as my initial reaction to the RME video called "Why still usb?"

I believe many of us are fine waiting for what may be called the RME UFX+ II

it should have USB4 AND Thunderbolt 4 

right?

(AVB etc. as add-on OPTION cards maybe good?)

I believe that makes perfect sense in 2024 ?

Re: UFX lll

I've had really good experiences with USB over the years, so I disagree with your idea that USB3 alone would not be well enough for an interface like the UFX III.

Back in 2014, I started using a UFX with USB2 and FW400, but USB ended up working better than Firewire.

Then, in 2015, I got a RayDAT and tested whether a PCIe card would give me any advantages in terms of CPU load or latency. I used the UFX in standalone mode, connected through ADAT, and found that it gave me no visible benefit over USB2 in terms of CPU/system load or stability. So, in my experience, USB2 worked just as well as a PCIe-based RayDAT.

I upgraded to the UFX+ in 2016 and found that using it via USB3 worked great, even with its high channel count of 188. And for even more channels, the MADIface XTC has 394 channels and is also well-supported by USB3.

In 2017, I wrote a blog article comparing UFX+ via USB3 and RayDAT via PCIe under load. I used a big Cubase project with 400 audio tracks, 2 VSTs per track, and 3 in the sum, so 803 VSTs in total. Even at the lowest ASIO buffersize of 32 samples at 44.1 kHz (or 64 samples at 96 kHz), there were no audio drops during playback, and the CPU and ASIO load was handled very well by my system (meanwhile a 7-year-old CPU). The conclusion was that there was no visible difference between using UFX+ USB3 vs. RayDAT PCIe based. Thunderbolt is "external PCIe" so it is compareable.

BTW, I just uploaded a new screenshot where you can see this test project with 400 tracks and 803 VST running on my current system with last recent Cubase 12.0.60 Pro:
https://www.tonstudio-forum.de/attachment/3003-11-2023-04-22-ufx-400tracks-load-test-44-1khz-32-asio-bufsiz-cub12-0-60-jpg/

Latency-wise, the difference between USB3 and Thunderbolt is tiny. I have a comparison chart of different solutions that I own(ed) that you might find helpful, see here: https://www.tonstudio-forum.de/attachme … es-v2-jpg/

If you're interested in getting some more information, like e.g. differences between UFX+ and UFX III and some recommendations, then please have a look at these two threads:
https://forum.rme-audio.de/viewtopic.ph … 62#p200962
https://forum.rme-audio.de/viewtopic.ph … 02#p217002

I would encourage you to try USB2/3 with the UFX series for yourself instead of relying on hearsay or unproven expectations. I also recommend getting a USB3 PCIe card with a supported USB3 chip, like the Sonnet card with FL1100 USB3 controller, to isolate your recording interface from the rest of your USB infrastructure. This can proactively prevent the addition of other USB-based devices from negatively impacting your connected recording interface.

One proactive tip, like I recommended in the above-mentioned thread (again the URL: https://forum.rme-audio.de/viewtopic.ph … 62#p200962). I would directly get a USB3 PCIe card with supported USB3 chip like the Sonnet card with FL1100 USB3 controller to fully isolate the recording interface from the rest of your USB infrastructure. It can proactively help, that adding more and more USB based devices (headsets, Bluetooth adapter, etc.) have no bad impact on the connected recording interface.

Re: UFX lll

@ramses    !!!

that is a kind and very helpful post - many will find useful - THANKS for that, from me*-)

So many good info's! - and on the preferred USB3 chipset(s) --  superb to know stuff like that!

It is very sad about the thunderbolt chips availability and the other bits detailed through the above posts.

I should briefly mention I have had terrific results with USB2 and USB3 also!!!

For live performance, CPU maximizing, and, well, just to satisfy "most flexible" and, 'obsessing on what's best' to match with computer ~~>>

I find myself having to accept that:

1)  the CPU hit USB has -- compared to Thunderbolt -- is real

2) that MY being concerned about 'CPU cost and latency' means I'm not a professional who needs to get on with being a professional and that I'm laughably more concerned about my perceptions. (meant sincerely, not sarcastically*-)


3) Anyone who wants one of the greatest interfaces EVER,  from the greatest proven company, should absolutely get a UFX III


My babyface pro is a happy little interface!


Many thanks again for great info and more, including "MC" and of course others!!! ~>  on earlier posts here - best wishes to all.

Re: UFX lll

BTW, Win10 already includes the drivers for the Sonnet card with FL1100 USB3 chipset.
Also nice: the drivers use the more efficient MSIs (message signalled interrupts), see
https://forum.rme-audio.de/viewtopic.ph … 26#p145426

Maybe the problems that you have were based on "bad luck", incompatible HW with 3rd party USB3 chips.

Such incompatibilities in HW can sadly always occur and, if I remember right, even with thunderbolt there could be issues.

The best is to ask people upfront or to try something out or you get a turnkey system where all such tests already have been made.

Re: UFX lll

I have an ADI-2 pro FSR and absolutely love the balanced headphones mode.  I realize this is primarily an audiophile feature but would love to see it added to the UFX III I recently purchased.  Is this feasible in the future?

Good question! Hope for this too. Was looking for a TB4 laptop (Intel only) but if I understand it all correctly, a Ryzen with USB-only will do for our UFX+ since TB functionality seems to be EOL as well hmm. So in the future (new laptops don't have tb3) we can't (correct me if I am wrong) use the full 188 channels via USB. Major bummer for us.

The studio machine has TB3 with a startech adapter to TB2 (ryzen) and it works super fast. USB on the other hand seems to have more load on my machine. So did this improve as well with the UFXIII?

And lastly will we be able to use the UFX+ with USB3 with full channel count in the future as the UFXIII seems capable...

Sorry, my bad. The full channel count does already work via USB3. Is this working also like a dream on AMD CPU's? Ryzen 5000 to 7000 series?

I just want to say that someone said Windows is an open ecosystem. I strongly disagree and believe it's a closed ecosystem. It's super difficult to develop for Windows. I've done it and got paid for it, but it's certainly not as open an ecosystem as on Linux, for example.

Re: UFX lll

What a beautiful topic!

I'm in a same boat with rfpm and some other guys.

I have RME Fireface UFX+. I use it with Mac and absolutely love it BECAUSE of Thunderbolt connectivity.

Whoever the speaking, Thunderbolt is faster and speaking directly to CPU, and I also can't imagine any reason to use USB over Thunderbolt.

Thus, when Fireface UFX III had been released, I was upset.


I don't know what is going on on Windows-department, but we, Mac-users always prefer Thunderbolt. It's a gold standard for high demanding devices.


I was planing to update my Fireface UFX+ to Fireface UFX III since I hear that UFX III use AKM chips and logics as in my also beloved ADI-2 DAC FS.

I also hear some advantages in Fireface UFX III over Fireface UFX+:

  • Better SNRs

  • Better THDs

  • SteadyClock FS

But my question is: are these advantages worth it? Will I receive any real better quality of sound? I'm a purist guy.

Is the loss of the Thunderbolt port worth the increase in sound quality? Is it, the sound quality, much higher? What do you think, guys?


Also I have questions to dear MC:

  • Are we going to see any Thunderbolt Fireface UFX in future? Or this is a final decision and I should try (buy) Fireface UFX III with its USB?

  • Which AKM chips uses UFX+ and which UFX III?

Thank you!

Re: UFX lll

Most of your questions are answered here, see also the links included in my post.
https://forum.rme-audio.de/viewtopic.ph … 39#p201239
It contains a detailed list of changes between UFX, UFX+, UFX III and also come calculations in terms of latency.

Thunderbolt can be regarded as "external PCIe" but this doesn't mean that USB3 is "worse".
With USB3 you also have a full-duplex connection, sending and receiving happens in parallel.

Bandwidth-wise, USB3 offers enough bandwidth to even support a MADIface XT with 196/198 channels IN/OUT.
The UFX III has "only" 94/94 channels IN/OUT, so also bandwidth wise you are on the same side.

Although I understand, that as an Apple customer, you might use thunderbolt a lot. Surely, also a requirement for Apple customers, because many use laptops and these are so slim, that it is better to have [also] thunderbolt ports, which are slimmer from plug perspective and where you can daisy-chain devices.

But from a workspace/handling/component-placement perspective, I prefer the 3 m max cable length of USB 3 compared to the approx 2 m of thunderbolt. Furthermore, with thunderbolt, everything is pricier. The cables and especially active extensions if you need more than 2 m. I also kind of "hate" the tiny thunderbolt plugs, I prefer the sturdier USB 3 Type-A and Type-B plugs.

The differences in latencies are really tiny and as I could demonstrate, you can also load your machine (I used the stress test of CPU-Z tool) up to around 98-99% CPU and with an ASIO buffer size of 64 samples @single speed I didn't get any audio drop.

As far as I understood RME (I am not from RME, I am a customer like you), there won't be any thunderbolt-based device anymore for the explained reasons, see forum.
If USB3 would not be a proven technology, RME wouldn't have offered it for the UFX III.

I upgraded from UFX to UFX+ and last recently upgraded to UFX III. UFX III is an excellent product.
For me important, quick converters as I am using the UFX III as parallel effect loop for my Marshall combos (stereo setup) and Lexicon PCM 81 and PCM 91 as external FX for amp and/or DAW, controlled by TM FX routing. Excellent solution, excellent recording interface. Works still perfect over a 10 year old PC. Fine tuned and upgraded heavily. Does everything reliably: Office, Gaming, Recording and extremely silent, my environment is very silent, around 28 dB.

Well, everyone has their hobby.

Are you trying to blame me for enjoying helping many people with their recording problems here?

Some things might seem off-topic to you. Then just skip over them if they don't interest you. However, I don't recall ever knowingly saying anything incorrect, and many people are satisfied with my advice. So what's there to complain about?

Of course, I understand if you prefer to hear directly from RME. But an answer is better than no answer at all.
BTW, if you read the forum regularly, you would have almost the same level of information.

And if I may give you a recommendation. If you do not want an answer from other people, then write RME an e-mail.
Should be clear that if you write via forum, that you get answer from all sides, RME and other customers.

The UFX III is a very good device. That's the short answer, and it hasn't gotten worse compared to the older flagship products. The converters are the same ones used in the ADI-2 Pro FS, and they are simply fine. If you want "the latest and greatest" for your monitoring section, just get an ADI-2 Pro FS R BE as well.

BTW .. Just recently, Bob Katz praised the ADI-2 Pro highly. And from converter perspecitve both devices UFX III and ADI-2 Pro FS are not far from each other, mainly different design/feature set.
As far as I remember RME never makes any claims what sounds better. Get the two devices and let your ears decide.

I think everyone can now see that you prefer Thunderbolt and that I apparently don't meet your standards.
Ok, so then somebody else on this topic ?! ;-)

Have a nice day.

Re: UFX lll

Well, I upgraded from Fireface UFX+ to Fireface UFX III. And want to say something and share some thoughts and measurements.

1. The quality of converters is much much better. Finally, this is the sound.

2. Fireface UFX III with its USB is even FASTER than Fireface UFX+ with Thunderbolt.

The latency in Logic Pro 11 on 96kHz with buffer size of 64 Samples was:
- with UFX+: 3,0 ms Roundtrip (1,5 ms Output)
- with UFX III: 2,9 ms Roundtrip (1,5 ms Output)

See the screenshots:

https://i.ibb.co/xDKD0NH/Screenshot-2024-06-15-at-23-06-54.png

But this is with DriverKit driver.

With Kernel driver Fireface UFX III shows even more crazy results:
- 2,4 ms Roundtrip (1,2 ms Output)

https://i.ibb.co/HBdjQ9F/Screenshot-2024-06-19-at-18-30-36.png


Thus, I'm happy with a new Fireface UFX III. Just amazing and ultimate product in all dimensions.

Maybe one thing: DAW-reported Latencies/Roundtrips are never accurate. I recommended use tools like REW for this.
F. ex: After you selected your UFX III in Logic, just change the Interface to your Built-in Speaker/Mic and click Apply. You will notice that the Latency does not change...

You write 32 samples @96 kHz, where did you configure 32 samples?

At least for Windows ASIO drivers
32 samples are the lowest ASIO buffer size for single speed (44.1/48 kHz sample rate)
64 samples are the lowest ASIO buffer size for double speed (88.2/96 kHz sample rate)
128 samples are the lowest ASIO buffer size for quad speed (176.4/192 kHz sample rate)

The reason is, the higher the sample rate, the higher the amount of data that is being transferred,
so with double the amount of data at double speed, you also need the double buffer size.

Even if Apple does not use ASIO drivers, the underlying transfer mechanisms are actually the same, and at double speed I would have expected Apple to use a higher transfer buffer, 64 instead of 32 samples. Is it perhaps a typing error, or where do the 32 samples @96 kHz come from, where are they set?

Thanks for clarification.

I don’t quite understand your question. In macOS we have 32 samples buffer size at 96 kHz sampling rate in DAWs such as Logic Pro and as well the same you can see on the on the RTL Utility screenshots. It’s not a typing error.

See the additional screenshot from Logic Pro:

Ok, many thanks for delivering this information, this is quite interesting.

Well, I am wondering, that ASIO has to use higher buffer sizes compared to Apple, although ASIO provides direct access to the recording hardware compared to Apple where audio has to go through Apple sound system additionally.

I would have expected that Windows and Apple share the same basic mechanisms for the selection of buffer sizes.
Therefore, I wonder, what the ASIO buffer size at double speed has to be twice as large compared to Apple
and wanted your confirmation of numbers, thanks for providing this.

It would be interesting if RME could explain the technical background.

Neither Cuabse nor Logic measure anything. They report numbers that are coded into the driver, and these are often enough wrong, sometimes even intentional, to fake short latency that isn't there. RTL Utility does measure, and also report the driver included numbers on the Log page.

Neither Cuabse nor Logic measure anything. They report numbers that are coded into the driver, and these are often enough wrong, sometimes even intentional, to fake short latency that isn't there. RTL Utility does measure, and also report the driver included numbers on the Log page.

That’s interesting. Didn’t know about that. Why then the numbers between real RTL measurements and Logic’s measurements are the same? Very good predication from RME’s side? :-)

They measure and enter the correct values, no marketing bs.

You already answered your question by yourself here...

the DAW measurements are actually quite accurate :-)

...by comparing these with your results from your RTL measurements.

Some geeks are discussing, and comparing interfaces here:
https://gearspace.com/board/music-compu … -base.html

Their current List: https://dawbench.com/images/DAWbench%20 … e-2024.pdf
Note they publish the results tested on different OS - so please consider it more like an orientation


You surely also have noticed, that RTL generates a real "Ping" Impulse. Logic, just reads the values, reported back - thats the Difference.

Made a Test (just) for you, to explain what i meant in my last post:

https://i.ibb.co/FJSsq3b/logic-rtl.png

Left side: reported values by Logic for IN/OUT of my FF802... Right Side:  I just switched the Input to Mic of a "dumb" Plantronics USB Headset.
So according to Murphys Law:
1,4ms - 1,1ms = 0,3ms Latency for this Mic??? - Never Ever!

If there are still people believing DAW calculations are accurate:
Buy cheap Headsets instead of expensive Units!
But before throwing your Units to Trash, contact me. I will recycle them for you ^^



Anyhow, if i may add my personal opinion:
I do not understand the hunting for nanoseconds in general here, if you make Music.
Why? Because this is not a "Real-Life"Usability Test. Its more like the gap between the consumption values of fuel by car manufacturers (which may be correct) and the real life on street.
   
Longer time ago, i made 2 scenarios, just for myself to see if the physics, once i learned are really true, lol...

1) Looping Back via a physical Cable, gives a quite more realistic Test. As it involves the DA/AD processing by the Unit (described in the RTL Manual here: https://oblique-audio.com/downloads/RtlUserGuide.pdf) - You will see, there are a few more milli/nanoseconds than via digital loopback. But i understood the sense of the loopback Button in TM. Anyhow - But still not a real life Example...

2) So I also made the RTL Measurement with a professional Kondensator Microphone, connected to IN of my FF, and the Monitor Speakers to OUT of FF. The distance between Mic and Monitors is about 4 meters in my case. As we all know: Speed of Sound (c) -> c = 343 meters/s - lets say ~ 3 meters/millisecond...
RTLs Results confirmed this absolutely. I had more than 20ms (if i remember right)...

-> So: If you just play a Synth, and we ignore all the equipment related Latencies, but your Speakers are 4 meters away from your Ears - calculate it yourself.
