I have recently had to replace the motherboard in my computer. After getting everything set up and loading all the RME drivers, I can see inputs from all three devices in TotalMix, including the 20 MADI inputs. Also, I MIDI over MADI control is working for all the devices, i.e. I can control gain, phantom power, pad, etc. from TotalMix 2.03. The web-based 12mic remote also shows everything as OK, including all the MADI routing. Mic signals into the Octamix XTC or the 12mic appear in TotalMix as expected. So far, so good.

However, my DAW (Reaper) no longer shows the MADI inputs as available (it did before). It shows the 12 UFX+ line and mic inputs, AES, and 16 ADAT inputs. Sound Forge also does not show the MADI inputs as available, listing the same inputs as Reaper.

In the MADIface Settings app (notification bar), only the UFX+ inputs are appearing under WDM devices configuration, i.e. 12 line and mic, AES, and 16 ADAT.

I have of course checked all the settings on the RME devices, and can't find any obvious problems (although I may have made an error without knowing it).

Maybe I have overlooked a setting somewhere in the menus of the RME devices. Any help that anyone could offer would be much appreciated.

I use several different DAWs. It's necessary that the 64 channels from the two FerroFish units arrive in sequential order in the DAW. At 88.2/96k, this happens automatically because the MADI channel count is 32ch per device. At 44.1/48k, I need to use a separate TotalMix workspace which uses the Loopback feature to send the second FerroFish's 32ch to DAW inputs 33-64.

Needing to use two different TotalMix Workspaces has been a major headache. We'll have a nice headphone mix built and refined tracking one song, and then that headphone mix is reset when the next song requires a different sample rate. Guest engineers are complaining quite a bit - if they forget to change the Totalmix Workspace, they won't see any of the 2nd FerroFish's inputs in their DAW, and I'll get a phone call and need to remind them of what to do, and to all of us as professional engineers seems like a hack workaround. Furthermore, using the loopback feature "prints" my TotalMix EQ/dynamics to the DAW, which is quite undesireable when using these features to refine the headphone and control room monitoring mix, yet needing to capture unaffected and clean sounds into the DAW. Again, explaining this to many experienced guest engineers goes something like this .. "the TotalMix EQ doesn't get passed to the DAW for the first 32 channels, but it does for channels 33-64". Huh?

Now I'm confronted with another hurdle. I want to expand my imputs and make use of the third MADI port on my Madiface XT2. In order to configure TotalMix to accommodate 96 sequential channels, I LOSE all of my hardware D/A outputs on the 2nd FerroFish, because those channels get "stolen" by loopback.

The solution is simple. An option within the Madiface XT2 control panel that simply leaves the entire channel count consistent regardless of sample rate. When the sample rate changes to 96k, TotalMix still shows all 64 channels for each of the 3 MADI streams - but the unavailable channels (33-64, 97-128) will effectively be dead - no audio - but the DAW will still see them, and therefore no channel remapping or Totalmix Workspace reset will be necessary.

If you think about this from my perspective, I think you'll see this is madness and for a high channel count flagship interface for one of the best companies in the world, is totally unacceptable that we need to create these odd workarounds. Please consider my thoughts on this matter. I would do anything to stay within the RME ecosystem, I love the hardware, software, company ethos.

Lastly - if anyone has any ideas for solutions I may be overlooking, I'm all ears!

Thanks for your time.

My current setup for location recording over MADI is:

Laptop (Windows) -- UFX+ <---  XTC <--- 12mic
                                  ------------------------->

Would it make sense to introduce a Madiface USB into the MADI ring for redundancy?

                                               Laptop
                                                     |
Laptop (Windows) -- UFX+  <---  Madiface usb <--- XTC <--- 12mic
                                  ---------------------------------------------->

I thought of another possible option with AVB (Which forces to run another cable from stage):

                                  -------------------------->
Laptop (Windows) -- UFX+  <---  12mic <--- XTC
Mac computer <------------AVB ------|                       

What do you think?

Thank you

I just wanted to share here in case this helps someone.  I spent days troubleshooting my RME UFX III MIDI Ports not showing up in any DAW or application at all on Windows 11.  I tried Nuendo 14, Cubase 14, Studio One 6.5, Studio One v7 and Studio Pro 8.  I also tried BOME translator and several local apps that can see all of your inputs.

To solve this for me, RME recently put out a Firmware Update in February 2026.  I was one behind.  I flashed it successfully within say 5 minutes.

Reinstalled all the latest drivers.  A dialog came up and told me to choose between my UFX III settings or all of my TotalMix FX settings.  I decided to choose TotalMix FX since I know I spent a month setting it up and saving all my backups.

After doing the above which shouldn't take more than 10 minutes with reboots all of my ports finally appeared in every Windows application and DAW.

Have a great day!

I checked whole RME lineup but did not find a solution.
Is there any current RME device that would convert 8 channels ADAT to AES/EBU to connect 5.1 Genelec system digitally to my UFX II ?
ADI-8 QS, which would be perfect, is not available anymore, even used.
We were using ADI-4 DD for that but it's gone now and it seems very hard to find a replacement.
I would appreciate any help, thank you.

If my Madiface USB is set as clock master (clock source: internal) and my M-1620 Pro is set as clock follower (via optical or coax), when I change the sample rate in the Fireface USB Settings panel or within my DAW, the M-1620's sample rate won't change accordingly (though sometimes, depending on the change and as highlighted in the manual, the two devices will achieve a lock or even a sync anyway). This is particularly noticable when I switch from 48 kHz to 96 kHz or vice versa. Those are the main sample rates I use for my projects.

I believe this is different behavior from when I've used ADAT or AES with other RME interfaces to sync a follower converter.

Is there any way around this such that I can let my DAW change sample rates on a per-project basis and not have to then manually change the sample rate on my M-1620 Pro?

And is this a particular limitation of the Madiface USB or does it apply to all MADI-capable RME interfaces?

Many thanks in advance.

I am sure you have had this topic a million times, I have read what I have found in the forum to try and solve this issue.

I’m trying to get my RME UFX III working with 1 x Ferrofish Pulse 16 with Ferrofish SFP Module Multimode, and 1 x Ferrofish Pulse 16 MX over optical MADI and I can’t get it to work.

I’m using SC-LC & LC–LC OM4 duplex cables, so as far as I understand that part should be fine.

everything set to 64ch
same sample rate everywhere
RME as master, Ferrofish on MADI clock
using optical
checked I’m not mixing up IN/OUT

With just ONE Pulse connected directly to the RME, I don’t have any issus. But when I daisy chain the LC-LC connection from one pulse to the other and back to Rme UFX III LC-SC i dont get any connection.
I figured I should mention that both pulse´s are the same firmware.

I did the routing bit for both of them so they dont share same "channels"

At this point I just want to know if I’m doing something wrong

I’ve just invested in a 12mic for location recording and have set everything up for a session over MADI - all working great, except… I can’t get any sound out of the headphone output - either for monitoring any of the internal mic pre channels or for my talkback over MADI.

The level meter on the 12mic display is showing a level, but is greyed-out, which the manual says is showing the input level to headphones relative to 0db. But there is no coloured level  (green/yellow etc) and so no headphone output. I’m sure I’m missing something simple, but I cannot even monitor a single mic pre, let alone my talkback (which is definitely routed right and showing the same grey level meter).

Does anyone know what I’m missing?
Thanks for any help!

• Mic input pops / clicking more likely due to plosives and organic sounds from my mouth than an issue with processing within Windows or at the interface.

• Clicking / pops and occasional crackles during audio playback (mostly at the start) seems to be unrelated to the physical interface itself. Perhaps more of an issue with Windows or DPC latency being too high / non optimal Windows configuration.

Hi,

I'd really appreciate any assistance with this.

I've not long purchased a UFX III (upgrading from a UCX II); I believe both devices shared the same issue but I've noticed it more so with the UFX as I've been experimenting more with it.

Windows seems to also crackle really bad with playback scrubbing of media content. Audacity is the worst for it but I also hear crackles at the start of Windows system sounds, playback of videos starting / stopping etc.

Can anyone help me out here as to what's going on? I can't seem to work this out myself.

So I connected the ADATs (2 optical cables to Digiface ADAT1 i/o and UFX ADAT2 i/o), flash my Digiface USB with CC software (CC 2 version). I've used the good quality USB-C - USB-B cable (but 5m) to connect it to my:

• Xiaomi 13 Pro. Unfortunately I got issues:

  1. All the apps mixes the sound to mono (Blackmagic Camera, system Camera, system Recorder). Cubasis LE 3 sees Digiface but won't record anything.

  2. I can't get any audio from the Xiaomi via Digiface.

  3. The clock source looks like it is set to internal even if I set it to Input 1 (ADAT1) before flashing.

  4. I could get undistorted (nice sounding) sinus with system Camera app, but with maaaany dropouts.

• iPad Pro 12.9 3gen:
  

  1. I got the stereo signal!

  2. iPad could send audio through Digiface!

  3. the sinus was distorted comparing to the one macbook was getting.

  4. Digiface wants to be master clock

• Macbook M1 Max (still using CC mode) :
  

  1. twodirectional audio works OK

  2. sinus is OK (with one glitch, might be because of the clock)

  3. Digiface wants to be master clock

I've uploaded my Reaper session with test signal and its recordings to https://pliki.lukowastudio.com/20260406rmecc/. (Yes, there are 44 and 48 kHz, I switched it to diagnose it better, also some apps converted the sample rate automatically without asking.)

Has anyone succeeded with similar setup? Any tips?

I posted this a couple of months ago in the TotalMix FX 2 Beta thread but I think the MADI forum might fit better:

I control an Octamic XTC via midi-over-madi setup like this: UFX+ -> M32pro DA -> M32pro AD -> XTC -> UFX+.
It often happens that Snapshots don‘t recall the gains or pad settings. Only when I manually change the gain a bit it will adjust. I can, for example, switch the pad on an XTC channel on and off every second in TMFX and it‘ll work maybe 60% of the time. I updated the m32pros to the newest firmware as control-messages where improved according to the changelog. Still not better.

Also, and I think this might be related: My UFX+ sometimes forgets all it's MIDI ports shown in TotalMix FX Settings
and only restarting the system solves it.

System:
MacStudio M4 Max
UFX+ via Thunderbolt 1.06, FW v112
Octamic XTC Software Version 26/47
M32 Pro AD and DA 3.06 v176

Best,
Frank

I'm under MAC M2 (Tahoe).
Is it possible to set the buffer size to more than 2048 ?
