Topic: Fireface UFX II problems with Bitwig Studio 2 Windows

Bitwig has a problem with the Fireface UFX ll. If I open the ASIO dialog from Bitwig and try to do changes, then the ASIO dialog freezes and I have to click a few times until the UFX setup dialog opens. And also If I save the changes in Bitwig, the ASIO Window in Bitwig again freezes and doesn't recognize the new setup unless I close and reopen Bitwig.

I have a project with 10 tacks 24/96 which with 128 samples of audio buffer is getting drop outs and crackles and with 256 samples just a bit better. CPU usage around 12%

With the older audio interface Focusrite Clarett 8Pre Thunderbolt I didn't have any problem. Surprisingly the same project works with 64 samples audio buffer without any drop out and crackle.

What I tried to fix that issue.
E clean installation of Windows 10 Pro, disabled all unnecessary features in Windows like antivirus, defender, graphically effects, set the CPU performance to high performance in the energy & power settings, set the processor scheduling to background services, deactivated the system sounds.... In the BIOS I disabled Hyperthreading, The Audio and Vt-d.
Installed the latest FF driver and the latest Bitwig version, connected the FireFace to the various USB ports, replaced a known good USB cable.....but still the same. (apart the keyboard and mouse, no other peripheral devices connected)

LatencyMon doesn't show any issue during the test.

My PC configuration: i7 7700K, Gigabyte GA-Z270X-UD5, 16 GB Ram Corsair 3000 Mhz, Samsung EVO 960, PSU b-Quiet 500 W.

The dealer nearby told me, that his configuration (Bitwig 2 and Babyface Pro) works fine and doesn't get any trouble.

Anybody an idea how can I fix the issues? A PCie USB Card from Sonnet with a Frisco Logic Chipset? (800€ vs 1999€ nice!)

Re: Fireface UFX II problems with Bitwig Studio 2 Windows

Which Win10 version ?
Which RME driver version ?
Which UFX II firmware version ?

Eventually an older driver version might help, like here: https://www.forum.rme-audio.de/viewtopi … 94#p130994

That was for a 802, maybe also helps for your UFX II.

Use an USB 2 or 3 port coming from chipset.

You could get an USB3 card with Fresco chipset, but this should also work with any USB 2 or 3 port coming from chipset. 30 channels i/o is not that plenty.

You also might be bitten by some rest issues in Win10 which can lead to blocking of audio related processes up to 100ms which is a lot. See also my blog article: http://www.tonstudio-forum.de/blog/inde … ing-EN-DE/

Win10 1803 should have fixed the issue around "Virtual Lock" parameter. But sadly 1803 introduces other oddities: https://www.forum.rme-audio.de/viewtopic.php?id=27106 (sry only available in german, try google translator)

Maybe also consider a Win 7 parallel installation until Win 10 becomes more mature, shall this be windows related, which IMHO can't be excluded.

But maybe you can find already a solution using an older version of RME driver, although I regard it as strange that the latest driver version shall have this issue.

Re: Fireface UFX II problems with Bitwig Studio 2 Windows

Try to disable MMCSS in the Fireface settings dialog (About) for the dropouts. Try to disable WDM for the freezes with dialog changes.
