<![CDATA[RME User Forum — [Solved] UFX+ Midi Ports Issue in Cubase Pro]]> https://forum.rme-audio.de/viewtopic.php?id=42910 Wed, 25 Feb 2026 19:44:18 +0000 PunBB <![CDATA[Re: [Solved] UFX+ Midi Ports Issue in Cubase Pro]]> https://forum.rme-audio.de/viewtopic.php?pid=249172#p249172 I installed again Totalmix v2.0 RC1 and everything is working as expected.

I confirm that the new driver is keeping the same UniqueIDs when the UFX+ is reconnected, and Cubase is remembering the correct configuration of the midi ports as expected.

One milion of thanks !! smile

Installing the driver has also installed Totalmix v1.99 and removed Totalmix v2.0, so I thought it wasn't compatible with version 2.0.

I will install again Totalmix v2.0 this afternoon and confirm if everything is working as expected.

Thanks @maggie33

The fix affects the TB MIDI Driver. Has nothing to do with the TM beta...

Please try Mac TB DK driver for UFX+, version 1.06:

https://www.rme-audio.de/downloads/driv … dk_106.zip

This one now takes over ID registering from Apple (which caused a random UniqueID), so when disconnected the devices will vanish (as expected and correct), but will now always have the same UniqueIDs when reconnected. That should fix it with Cubase.

The issue is fixed, thanks!

Will you copy this fix to the beta 2.0?

Yes, absolutely. Thats what I meant...  Lines 745-865 represent the device if its turned on (as your 2 diff's from #15 show in: "745,865d744" and "744a745,865")

Thanks for confirming my "theory".

Thanks @MC as well.

Thanks for your help @maggie33 !

My .mcfg file has only 747 lines after turning the UFX+ off. These are the 3 last lines of the file:

745       </array>
746   </dict>
747   </plist>

But my .mcfg file has 868 lines after turning the UFX+ on. These are the 3 last lines of the file:

866       </array>
867   </dict>
868   </plist>

It seems that when the UFX+ is turned off, all the info of the UFX+ is removed from the mcfg file…

The device is completely removed, powering the unit off and freshly generated powering it on...
Instead "marked as offline" (greyed out) in AMS, the device disappears completely. Right?
As described here: https://support.apple.com/en-ca/guide/a … %20dimmed.

Thats why the uniqueID's are freshly generated on power on/reconnect, what causes Cubase to recognize a new MIDI device (which is enabled by default).

----

Not 100% sure (as I don't own a TB unit), but maybe this info helps to identify the cause easier.

- The de.rme-audio.firefaceUSB3Midi (afaik, UFX+ uses it in USB Mode, too) driver uses the "offline key". Thats what makes Apple's AMS "happy"... This key marks the device offline/greyed out in AMS instead deleting it. 
I used my UFX3 here, just to show what I mean:
(the "-C 1" param just additionally show the upper/lower line. while the ! marks the real change):
Thats my result here:

diff -C 1 \
  ~/Library/Audio/MIDI\ Configurations/MySetup.mcfg.UFX3on \    
  ~/Library/Audio/MIDI\ Configurations/MySetup.mcfg.UFX3off  
....
*** 2068,2070 ****
              <key>offline</key>
!             <integer>0</integer>
              <key>uniqueID</key>
--- 2068,2070 ----
              <key>offline</key>
!             <integer>1</integer>
              <key>uniqueID</key>

To sum up, jordkits's issue indicates the same cause as my personal experience was.. (a while ago I was developing a midi driver and stumbled over exact the same point)...
I am pretty sure the TB driver  (de.rme-audio.RMEPCIeMidi) calls MIDISetupRemoveDevice (whatever triggers it) on poweroff/disconnect, instead setting the kMIDIPropertyOffline
See: https://developer.apple.com/documentati … y%20state.

(vs.: if system is rebooted, the TB driver doesn't get a "offline" trigger and doesn't call MIDISetupRemoveDevice with the result that the midi device persists in the config, as jordkit mentioned)

I have realized that the mcfg file is changing everytime the UFX+ is turned on, but also every time it is turned off.

This is the Diff Terminal reply after turning the UFX+ off:

Does this also happen if you reboot rather than switch the device off and on?

Sorry I don't understand, do you mean to reboot the computer with the UFX+ on?

We will have a look, thanks for the details. Does the same happen when using USB instead of TB? This might be an issue specifically with that platform.

I have never used my UFX+ through USB, maybe it would be a solution (maybe thunderbolt protocol always change the ids?)

It is true that the other audio device I have is a USB device and it is not causing the midi port issue in Cubase.

Unfortunately, it is a little bit complicated to me to connect a usb cable to my ufx+ now, cause I have a part of the rear panel of my UFX+ not accessible and I would need to dismount it, and it would take me quite a while.

If you agree, I would prefer to wait for your first feedback on this issue before dismounting and mounting it.

But if it's necessary that I test the usb connection, I will do it, no problem at all.

Is it ok for you?
