In beta 12 we improved the 'compromise' a bit by showing an edited state of the REQ preset (by flashing), so the base of the current settings is still revealed.

Hello,

here to report a little graphic bug :
When you use the "gain" button in the dynamics section, it draws a red line on the right of the graphic visualisation, which can be removed only by closing the section, and it mays need many retries to clear it.

Thanks for the software !

Thanks to the entire RME team for their attention and effort.

All the best

You are on AMD?

Kind of same thing happend to me few days ago, but I am still on beta 11. I was watching some movie in vlc player, and all of the sudden no sound on pc at all. I restart PC and everything was ok after that. It happend only twice now in week or so, so I couldn't figure out what was the cause.

I am on Intel 14th gen.

Yes, I'm aware, this is likely related to the TMFX 2.0 direct3d 12 implementation clashing in some way with AMD drivers.

As I said in my comment, the process dies. There's no TMFX exe visible in task manager. When I try to run it myself, I see it pop up for a moment and the process dies again unless I go and fix it by running tmfx 1.99 first, closing it completely and running 2.0 again.

It doesn't happen on every boot up, yesterday it happened for the 3rd time, today it hasn't, I usually keep my PC on for the whole day.

Hi,

Bug Report: Fader Group Behavior in TotalMix FX Beta 12

Description: When switching between snapshots that involve stereo-to-mono channel changes, Fader Groups incorrectly expand to include unintended channels.

Steps to Reproduce (YT video https://youtu.be/rHafu_KL6lA):

1. Save Snapshot 1 with channels 1 and 2 configured as Stereo.

2. Modify configuration: switch channel 2 from Stereo to Mono.

3. Create Fader Group 1 linking faders of channel 1 and channel 2.

4. Save Snapshot 2 with this configuration.

5. Switch back to Snapshot 1, then again to Snapshot 2.

6. Observe that Fader Group 1 now links three faders (channel 1 stereo, channel 2 mono, channel 3 mono) instead of the expected two faders (channel 1 stereo, channel 2 mono).

Expected Behavior: Fader Group 1 should consistently link only the two defined faders (channel 1 stereo and channel 2 mono) across snapshots.

Actual Behavior: After switching snapshots, Fader Group 1 incorrectly includes an additional fader (channel 3 mono).

Impact: This behavior causes unintended grouping and control inconsistencies, making snapshot recall unreliable in configurations involving stereo-to-mono changes.

Environment:
Windows 11 25H2

Hi,

Bug Report: TotalMix FX 2.0 beta 12 – crash on startup with specific screen resolution parameters in config file.

Issue Description: The TotalMix crashes immediately upon startup when specific configuration values are present in the file last.FirefaceUCXII1.xml. This file is generated automatically by the application during a previous normal shutdown.

Steps to Reproduce:

• Completely exit the application (not just close the window) so that it generates last.FirefaceUCXII1.xml.

• Ensure the configuration file contains the following values:

<Frame0>
    <Window>
        <val e="WinPos.left" v="0"/>
        <val e="WinPos.top" v="0"/>
        <val e="WinPos.right" v="2560"/>
        <val e="WinPos.bottom" v="1600"/>
        <val e="ScaleType" v="2"/>
        <val e="IsMaximized" v="0"/>
        <val e="IsFullScreen" v="1"/>
        <val e="FuncType" v="0"/>
    </Window>
</Frame0>

• Launch the application.

• The program hangs and then closes immediately.

Condition Triggering the Bug:

((WinPos.right - WinPos.left == 2560) &&
        (WinPos.bottom - WinPos.top == 1600) &&
        (IsFullScreen == 1)) 

If either the window width or height values differ from 2560 or 1600, the application does not crash.

I think this is the issue. I had the problem happen today again and for me it's directly tied to whether I have TotalMixFX in fullscreen mode when I shutdown the PC.

I looked up the window settings in the last.FirefaceUCXII1.xml when TMFX was unable to open and this is how it looked like.

After changing the fullscreen variable to 0 and retrying to launch it worked. Then I set TMFX up like I always have, on my 3rd monitor in fullscreen, then closed TMFX through tray. This is how it looked after reopening the xml:

What I think might be happening is a monitor layout mismatch vs the last.xxx.xml config, my pc has 3 screens and i cycle between two display output configs, outputting to my main screen + totalmix screen for the first half of the day and 3 screens total for the rest of the day. Not sure where the issue occurs exactly though as I don't change the layout of the screens when totalmixfx isn't running. Might be related to when totalmix actually updates that xml file?

Just an FYI, seems having Gsync on causes flickers when TM is open AND selected with the mouse, if I select another window the flickering stops, this all goes away when I turn Gsync off.

Running Beta 12 and W11 Pro....Loving the high contrast look, please do some more skins RME!

Hi,

Cosmetic issue (in beta 13):

When right‑clicking on a Channel in the Hardware Inputs and selecting Change Channel Layout, the Channel Layout window does not automatically switch to the Inputs Tab. Instead, it displays the last used tab and requires an additional click on Inputs Tab if Playbacks or Outputs Tab was previously active. In comparison, for Software Playback and Hardware Outputs, the correct tab is activated automatically.

Thanks

Oh wow, what?  You guys implemented my suggestion for a fullscreen shortcut??

ICH LIEBE EUCH!!!  Vielen, vielen dank!

Thanks for updating the most stable and reliable drivers/software in the industry. Can't wait to try it when is officially released.

Hey guys,
I noticed that in the new Totalmix 2.0 (Beta 13) the Fine mode modifier for the faders doesn't work (Shift Key + Scroll or Mouse Drag).
If I switch back to the old design it still work as expected!
Thanks!

Any chance improved Mono/Stereo channel handling will make it into the TMFX 2.0 development???

Love the new look!

But what about changing the window decoration to match the dark mode on Windows 10 when that is enabled? It's currently bright white and it doesn't really match the new aesthetic.

The Mac OS screenshot looks much more pleasing.

Anyway, really appreciate the resizable UI and the new loudness meters. Great stuff!

Nice one!

Bug Report in TotalMix FX 2.0 Beta 13

Issue: GUI malfunction in Room EQ window.

Description: After opening the Room EQ window, minimizing the main TotalMix window (either via standard minimize or using Windows + D) and then restoring it, the Room EQ GUI stops visually updating when adjusting parameters. The parameter values do change internally, but the interface does not reflect them. Closing and reopening the Room EQ window restores normal visual behavior and shows all previously applied changes.

Steps to reproduce (as shown in the attached video https://youtu.be/VF1QBHxKv7s ):

• Open Room EQ window.

• Minimize the main TotalMix window (regular minimize or Windows + D).

• Restore the main window.

• Adjust any Room EQ parameter.

Environment:

Windows 11 25H2
UCX II (drv 1.276, SW 36) / TotalMix FX 2.0 beta 13
CPU/iGPU Ryzen 9 7950x (drv Adrenalin 25.12.1)
dGPU RTX2060 12GB VRAM (drv 591.44 studio)
4 screens: 2560x1600, 2 x 1920x1200, 1920x1080
96GB RAM

I'd like to also report that the RoomEQ window has something wrong with scaling, every time I open RoomEQ it spawns a window that spans over my 3 screens instead of scaling to the monitor im currently using totalmix on. Resizing it works, but when I close RoomEQ and then reopen it, it goes very big again.

Basically, it is the case that quite a few windows of the TotalMix FX program will not open in the middle of the window, but rather arbitrarily somewhere at the edges. For example, the 'Settings-window' etc. When operating with several monitors (screens), the window chaos seems to become even bigger. For example, with the Room-EQ window. I have already addressed this circumstance here in this thread. I really hope that future TotalMix FX versions will basically open the other dialogs in the middle of the window and remember the state of position.

Here comes beta 14, addressing various feedback (aka bugs and issues) from this and the other thread. Download links in first post - Check it out!

- gain labeled dB

- Room EQ windows are now cached with size and scale information

- Window sizes are now correctly adapted when changing between monitors with different DPI settings

- In Classic design REQ windows were wrongly positioned as well – fixed

- Minimizing the app the REQ windows were not minimized simultaneously – fixed for both taskbar and tray icon

- Nearly all dialogs will now be opened in the middle or above/below the respective element, reducing mouse travel

- Fixed wrong menu entries for Fireface 802

- Menu entry ‘Store current state into device’ was disabled

- Undefined title bars of windows are now set to black (menues unaffected)

- Removed several write processes during shutdown that were no longer needed

- Re-added the Load and Save buttons in the ARC Settings dialog

- Loading Snapshots with Groups (Mute, Solo, Fader) after Snapshots without Groups could cause Groups to not load

'nuff said!

Well done! Thanks !

+1 fully agree; a black title bar doesn't look good.

I also think the readability of the right side of TM FX  still needs to be improved.
For example, titles of sections like "View Options", "Snapshots", "Groups", "Layout Presets", ..
For the font, I would use a brighter "white" to give it more contrast and I would use capital letters again
at the beginning of words to increase visibility/separation of the different areas.

Agreed, also since yesterday (and this might be because of this weeks w11 security update) I can no longer execute a shortcut from taskbar or desktop, as windows now says this is a potentieel malicious internet shortcut. The tray icon, or executing from the program files / rme folder works fine. But a shortcut from tmfx in that folder doesn’t?
