Re: Official Linux drivers/tools a possibility?

Hey Waedi,

i am actually using reaper @ Linux Mint at the moment, but routing through reaper ( same with any DAW without dedicated hardware ),
introduces a delay.

Totalmix is latency free, which is an important issue in pro audio recording.
Many artists  feel uncomfortable recording with monitoring latencies above 10 ms, and recording like 40 tracks at once
is  more safe @  higher buffer settings, you just cant risk to introduce possible pops and clicks resulting from a low buffer size.

Therefore Totalmix can be used as a great multitrack headphone monitoring mixer using an  Ipad for each artist to control several individual headphone mixes.

Re: Official Linux drivers/tools a possibility?

@arnojordan

Linux Mint by default is not optimized for low-latency audio (e.g., monitoring latencies below 10 ms). It ships with a generic kernel without real-time or low-latency patches. While it’s possible to manually install a low-latency or real-time kernel and configure JACK with real-time priorities, this requires additional setup.

For out-of-the-box low-latency audio performance, specialized distributions such as Ubuntu Studio or AV Linux are recommended. Using generic distributions like Mint involves further customization and tuning.

Re: Official Linux drivers/tools a possibility?

Hey Ramses,

i know this and tried that, even with low latency kernels it is impossible to get low enough while recording 40plus tracks at the same time.
Unfortunately we do not need low latency, we need no latency ;-)
And a.f.a.i.k that can only be provided by Totalmix.

Hi Arno,

"no latency" is not possible therefore I talked about "low latency" and more specific "under 10ms".
I choosed my wording carefully, because not for every DAW project/load the lowest buffer sizes are possible.

You can read my blog article here, which RTL (round trip latencies) you can expect from different solutions:
https://www.tonstudio-forum.de/blog/ent … cts-en-de/

RTL means time for AD and DA and the transport to/from the computer.
Even if we take the transport of audio samples over USB/PCIe/... out of the equation,
so if you have a direct flow from HW input to HW output you will have:
a) converter latency for AD and DA (where the more modern RME products have the faster converters)
b) around 1-3 samples (I do not know it exactly) latency for the transport of audio on the card.

Furthermore, it sounded as if you are not fully satisfied with your current setup in terms of latency.
And this is no wonder, because the Linux distribution that you choosed is not optimized for near real-time processing of audio.
So you should try a distribution that is optimized for such tasks and check how the latency improved.

EDIT:

I wrote you this with the intention to give you an idea of how you could perhaps improve the current situation
regardless of the topic of Linux support for RME drivers and tools.

Re: Official Linux drivers/tools a possibility?

Hey Ramses,

you are wrong, no latency is possible with totalmix because its core routines are implemented into the rme hardware.

i can use Reaper on Linux mint to record, i just need to use a safe buffer size. Why should i use a real time kernel if
it does not help me to avoid latency at all ?  Totalmix is doing exactly what i want, just like a hardware desk.
I just do not want to argue with my clients, i want them to know there is no latency, giving  them the peace of mind they need to perform as good as possible.

Re: Official Linux drivers/tools a possibility?

But even there you have AD and DA conversion in the signal path of audio and the transport over the recording interface hardware also needs something around 1-3 samples. It has been mentioned here by RME in the forum.

So if you would take an RME Fireface UC, see manual ch 33.2 Latency and Monitoring

Time for AD at 44.1 kHz: 43,2 samples (0,98 ms)
Time for DA at 44.1 kHz: 28 samples (0,63 ms)
Time for processing the sample in the FPGA, around 1-3 samples.

So we talk about a latency of around 43,2 + 28 + 2 = 73,2 samples = 1.66 ms (@44.1 kHz).
1,66 ms is not "zero latency".

If you monitor over the DAW you have to add the time for transfer to and from DAW to get the full so called "RTL".

About what latency are you talking, please?

To your other topic (which is not a linux topic).

The most awesome thing that may spark a revolution for Linux audio  would be the possibility to include a vst plugin support build into Totalmix,

It has been discussed several times in the forum that there will be no VST support in TotalMix FX, e.g.
https://forum.rme-audio.de/viewtopic.php?id=28535
https://forum.rme-audio.de/viewtopic.php?id=36598

Also see RMEs answer:
https://forum.rme-audio.de/viewtopic.ph … 13#p139913

In addition to what has been said in those threads, implementing it wouldn't be straightforward at all.

1. There is no actual audio passing through TotalMix FX.
TotalMix acts as an ASIO client and controls routing and certain settings on the recording interfaces — nothing more.
Trying to route all audio flows through TotalMix FX would be completely counterproductive in my opinion.
You’d end up with the same latency problems as when routing through the DAW — so you might as well just do it in the DAW directly.

2. Loading VST plugins directly onto the recording interfaces would also have a major impact on the system design.
Even if you were to go that route, you’d run into the same limitations as UAD and would need considerable onboard DSP power.
And at that point, you can forget about using standard third-party plugins — they would all have to be ported to the specific DSP architecture. How is that supposed to work?

If you don’t want to handle it in the DAW, just use a tool like LiveProfessor and host standard VSTs there.

That's a bit confusing statement. TotalMix not only stands for the software remote GUI, but also for the DSP mixer itself. So there is audio going through TotalMix. But not through the GUI software - except the Babyface.

ramses wrote:

I find this also misleading. TotalMix is not an 'ASIO client'. The only ASIO in TotalMix is found with the externally added FX of the Babyface.

Re: Official Linux drivers/tools a possibility?

Thanks for the clarification. Yes, my statements were not sharp enough.

I have thought a little further on that topic.

The question here is also what the expectation is.

Scenario 1:

Existing VST2/VST3 plugins could not be loaded into the FPGA or DSP on the recording interface, as they are not binary compatible.
So, if it is to run on the hardware, then VSTs would need to be developed and compiled for the particular DSP hardware.
The next thing is that it would possibly involve a hell of a lot of work to implement this with the flexibility of a DAW, where you can choose to use the VST as an insert or a send effect.
Another point is that it is rather unlikely that it would be usable on any existing RME device, as you would need additional DSPs for that. Maybe even more powerful FPGA.
So, all these efforts would not give any benefit for customers for their existing hardware and any potential new hardware would be a lot more expensive due to additional components needed and the development of new/additional VST that can be loaded into the additional DSPs.

Scenario 2:

If you want to use existing VST2/3 plugins, then they have to be loaded by TotalMix FX on the PC.
Then the audio flow would need to be routed through the PC.
You would also need many additional channels for the implementation of insert and send effect and the communication between recording interface and PC where those VST would be executed.
Look at the Babyface Pro, inserts (EQ) are implemented in the FPGA, but delay could only be implemented as a send effect which is shared between all of the channels and needs an additional (hidden) channel between recording interface and PC.
For multiple VSTs as inserts and sends you would need a lot of additional channels.
I think this would definitely weaken the stability and concept of the current mature TM FX design.
I would also introduce additional latency that can be quite high depending on the buffer size that you choose.

Re: Official Linux drivers/tools a possibility?

The new macOS driver with CC mention is great news, perhaps it's a small step to supporting TotalMix on Linux in the future, since now TotalMix seems to be working with CC mode.

Re: Official Linux drivers/tools a possibility?

I started working in AI and needed to use Ubuntu, and I am baffled to find out that RME doesn't support Linux...

Apparently since punkrockdude open this thread in 2018... Wow!?

I read the whole threat, and realized the problem. But also learned that some "other" companies managed to support Linux
with their audio drivers... So, it is still a little ludicrous...

Is there any alternative solution to this absurd situation, like a third-party ASIO driver or something like that that can fix this problem?

I won't be recording anything with it, only playback... I have a UFX...

I'm aware of class-compliant protocol; however, unless I have no choice, I would want to avoid switching back and forth...

cheers

Well, I do not know in OP´s case, but AI could do many things in respect to sound. AI is, beside others, used for signal processing, signal/speach analysis and signal/speech synthesis. And as an aid to setup different plugins....

Well, I'm not sure the relevance of me wanting to use RME UFX in Ubuntu, along with me having interest in AI, while having an inquiry.
Do I need to qualify to get an answer? SOL (smiling out loud)

I am a musician who has a home studio. Well, I am an ex-musician, and also a programmer..... Well, an ex-programmer...

However, I got into agentic AI work, thus the Ubuntu. Preferably I wanna be able to have verbal communication with agents, and if possible I wanna avoid the circumstance where I need to obtain some dinky and cheap audio card. I'd rather achieve my goal with RME that I already own....

And yes, thank you Kubrak. Although the information you provided wasn't focused on helping me, it was rather focused on helping to educate our 'market consultant friend here, and everything you said is true, and have that desired educational value for the right target, so well done... smile
One can also make use of AI to produce plugins. Furthermore, AI could play a role in psychoacoustics, studying how sound affects human perception and emotion, leading to innovative therapeutic audio applications. 

But, I'm mainly interested in AI agentic work, which involves developing and training artificial intelligence systems to act autonomously or make decisions without explicit human intervention. This concept delves into the capabilities of AI agents to understand, learn from, and adapt to their environment, thereby exercising a form of "agency."

So, that's my story...

Re: Official Linux drivers/tools a possibility?

I am not on Linux, but from what I know, you may use Class Compliant mode of RME interfaces on Linux. Many of RME interfaces do support CC, but not all.

Re: Official Linux drivers/tools a possibility?

Yes, CC mode is available, and thank you all. However, it would have been more useful if I didn't switch between Windows and Ubuntu several times a day.

Anyhow, I do have some alternative solution scenarios supported by Claude.

I'm hopping to get lucky! smile  I'll share my results here...

I have a UFX USB, so... But also, I'm not too excited about GitHub projects... mostly.

Re: Official Linux drivers/tools a possibility?

I would also love official RME drivers for Linux. Especially since in 2025, more and more people are making the switch to Linux 100%. Yeah, we have tools like WinApps and VMs, but let's face it, it's not as great as having a native solution.
RME makes rock-solid sound cards; I would be sad to switch over to another company just because the drivers aren't available, especially since options with 32 to 64 I/Os are quite rare, which the Digiface USB permits us to have.
Did the position change yet? Are we soon going to be able to just ditch our OS to finally be able to be 100% on Linux?

Re: Official Linux drivers/tools a possibility?

I'm here to signal my interest in officially supported drivers and software for Linux, too. Some kind of official information about Linux setups, best practices, do's/dont's would already be a great starting point.

Because I feel a strong need to act upon my privacy-related, as well as ethical concerns surrounding both Apple and Microsoft. And I've got the impression, I'm not the only one. I mean, even official administrations in Germany start moving away smile As much as I understand these things aren't directly related to audio/music production, yet: As creative/musician/sound-designer, these impact my integrity as a human being.

To prevent misunderstandings: I understand this is beyond the scope of the products I bought. It's not a demand; it's a wish.

Re: Official Linux drivers/tools a possibility?

Just doing the same as above here, would love to see official support as it's the main thing stopping me leaving Windows behind at the moment. It's great that people are making their own solutions but I'd like a bit more of a stable base than that.

I was amazed to find that my Babyface Pro FS and UCX II had better latency than Windows despite being in class compliant mode with zero tweaks done in the Linux OS. I imagine it'd rival MacOS with dedicated drivers.. Proper access to Totalmix is the bigger thing though.

I wonder why you use linux at all then? Your linux kernel and alsa sound are based on open source...
The location where the sources are published does't matter (for me)... Its an "official" alsa-project - sure only for firewire connected units...

Maybe useful for 802/UCX users:

Works very well with my FF802, as it directly communicates with the kernel's alsa via the snd-firewire-ctl-services...
