Yes, I'm interest.
When the song is out of time, that sounds like Ableton lost the connection to the driver Core-audio.
Ableton interrupts the delivery of audio.
The audio-interface can't help out when audio is missing from the source.
You could make a test and play a few hours some songs from another DAW, Reaper and focus on dropouts ?

hey guys, thanks for the quick reply!!!

https://www.dropbox.com/scl/fi/zzpw9u0l … q&dl=0

here i bounced one moment on stage with a drop out. i included the click track for better reference...

in this example it happend that the drop out was pretty much still in the grid (quater notes) but other times it was completely messed up...

hope this helps

yes, that's what I mean , reproduce the fail with another DAW.
You can use Reaper for ever for non-commercial use.
After the 60 days nothing will happen.

I mean you don't need to build up exactly the setup as in Ableton, just put a song into reaper and play it in endless Loop until the test is done.
Because how should the audio driver have the ability to disturb your Ableton in that way to bring the project out of timing and make audio dropouts.
An audio dropout yes, this can happen thru the driver or the interface.
But inside a DAW functionality ? I highly doubt the RME driver can do a mess there.

You did a fresh MacOS install on a new computer, therefor Ableton is also a new version.
After 20 years there has changed a lot in the tech background.

Also the question, how is the interface connected to?
By USB ? And wich driver exactly did you install ?

Hey, so i downloaded Reaper and I’m doin some testing now…
Btw: firmware:  v55
Driver: v4.12
And i use the ff ufx+ with a usb3 (blue) to usbc cable

Like i said before: when i freshly installed OS on my mbp m1, i tried the kext driver first (because it has better performance) but unfortunately it had dropouts too…
So i tried the driver kit driver which i still use now

On the M1 Mac, the Thunderbolt connection works without issues. USB has problems on some of the Apple Silicon systems.

If you can get an Apple TB3 to TB2 adapter, install the Thunderbolt driver and use that instead of USB.

I did not read (or missed) which macOS you currently use.

Hey guys, i found the tb2 to tb3 adapter but  i absolutely can’t find a thunderbolt 2 to thunderbolt 2 cable!
Even chatgpt couldn’t find a seller!
Am i missing something??
Am i really the only person with a ufx+ and a MacBook Pro M1 ? Is everyone else connecting their interface with usb3?

Please can someone provide me a link to buy this tb2 cable cause next week i gotta play at a wedding!!!
slowly this whole dropout issue gets pretty annoying! I mean so far i did spend around 60hours to solve my dropouts! And i earn my money with music but my ufx+ has to be reliable again!

Would even consider to sell the ufx+ and get a ufx3 instead but its just that i don’t really need the extras channels…

Please can someone help me!!!

Hhmm strange, both of your links say either “not in stock” or “currently unavailable “ ….,
I’m based in Austria/Europe

Thanks waedi for the link but that’s exactly what I’ve been using since the very beginning! But a few posts above jeff said on some apple silicone machines the usb3 doesn’t work properly that’s why I have to try the thunderbolt connection…

As far i know it’s the exact same plug but the protocol is different! Thunderbolt has a chip inside the plugs which acts like a pci connection and mini display is an apple protocol purely just for external screens…
so it has to be a dedicated thunderbolt cable
As far i know

This is not a Thunderbolt cable. It's a Type-C to mini-DP monitor cable, to be used with Type-C outputs that support DisplayPort alt mode to connect to a display. It will not work as a TB3 to TB2 adapter.

Again, a Thunderbolt cable is active (in the sense they have electronics to make a handshake between the host, the cable, and the connected device; they not necessarily have signal amplifiers) and must support the protocol, that's why they are significantly more expensive compared to regular miniDP or USB-C cables. The cable you linked before is strictly for connecting displays to DisplayPort-enabled Type-C port, which does not require an active cable. The description on Amazon page even specifically mentions this.

The white mDP-mDP cable you link here from the digitec.ch site will also not work as a TB cable due to it being passive.

In short, I would not bother with TB for connecting an audio interface when I can use USB, which is simpler, cheaper, more reliable in practice, and is a much more flexible connection.

I would try to write a shell script which terminates not needed processes on macOS and check whether audio drops vanish.

If you use ChatGPT it can write you such a script. In a good case of luck it is a working script.
Be warned, you can't trust ChatGTPs proposals.
The quality is between good and crap, sadly often crap.

At least it can give you some ideas as a basement.
But I would definitively review every line whether it looks sane, safe, reasonable.
Then refine it step by step.

This under the assumption that many audio drops will most likely come from background processes and network activity.

Then another shell script to reactivate most needed services like WiFi, BlueTooth, TimeMachine, Spotlight.
Or simply reboot to come back to the default state of services.

If your system doesn't perform well with the UFX+, the UFX III won't change that, as much as we'd appreciate you buying more RME gear...

Have you tried all available USB ports? Is this a direct connection? Sorry if I overlooked something in the long thread.

There were a bunch of posts on this forum about a very similar issue with stutters and dropouts on M1 and M2 Macs a couple of years ago, and AFAIR the problem correlated with higher levels of "memory pressure" (or something like that; I'm not a Mac user myself). And there were reports that it was largely addressed in the next macOS release. So you might look up these discussions here, perhaps there are some useful tips.

As to the Thunderbolt workaround, I don't believe this is a good solution. It may or may not work, and in any case there are many doubts regarding its future, at least for audio.

BTW, the RME interface itself has little to do with the issue. It just manifests more prominently due to the high channel count, but there were also quite a few reports from people who had it with dual-channel USB interfaces and DACs.

Just ordered the original apple tb2 - tb3 adapter and i ordered a used original tb cable! Cause i can not find a new one!! Wherever I looked it was sold out…
As soon it arrives and i made some test i‘ll get back to you… thanks for the help

The issue I am referring to affects USB playback only. PCIe and Thunderbolt are not having the same problems on the affected Macs.

We had cases where the flashing mic symbol indicated connection issues to the wirelessly connected iPhone, leading to dropouts...

Hi there,
I´m having these dropouts as well with the following setup:
Mac M1
Sonoma 14.6.1
Digiface Dante (firmware v57, driver v4.16)

With dropouts the yellow/orange microphone symbol disapears.
Sometimes dropouts are just one/30min, but sometimes one/minute.

I try to use my Digiface on all my jobs first, but when dropouts start I always change to my UCX on USB, which just works fine.
hmm. Ideas?

thanks
Christoph
