Any new updates on this?
We are most unfortunately at a dead end. Steinberg will do nothing to help fix this, even if an audio interface manufacturer wanted to help. They feel it’s not their problem. I ended up buying a Pro Tools subscription for tracking because Avid’s software works just fine with aggregate devices (as do all the other competitive DAW platforms). I’m beyond frustrated. It’s a Steinberg-only problem and they won’t do anything to fix it. I’ve been using Cubase since 1998 and Nuendo since version 1.0 in 2000.
I feel you on this.
I got Logic Pro so I tracked with it yesterday. Having an iPad is really cool to use with the aggregate feature. Shame that Steinberg won’t do anything about that issue.
I am here because I was searching the webs out of frustration because this works intermittently with Cubase 12 and Monterey 12.4. Fwiw my hardware IS STEINBERG HARDWARE (a UR242) and I just want to agg it with other things. =/
I have an update at least if you are using Lynx Aurora(n) and/or Hilo converters over Thunderbolt (TB3 in my case).
As some may know, Apple is in the process of forcing driver developers in macOS to move away from kernel extensions (KEXTs) to their new Audio Driver Kit model with driver extensions (DEXTs). The main difference to me is that it gets 3rd-party code out of the operating system kernel (KEXT) which risks security, stability, requires reboots to update, etc., and puts the driver code entirely into user space (DEXT) where reboots aren’t required to update the driver, it’s much safer overall for the OS, etc. The new driver model is completely different from the old kernel extensions and requires audio manufacturers to do a good bit of development to support this new standard.
Fortunately for my situation, Lynx has a public beta going now with this new driver format. Download it here:
I helped them out with testing over the past couple of weeks and am happy to report that Cubase 12.0.40 running on macOS 12.6 with this new driver works with my 2 x Aurora(n) / 1 x Hilo aggregate device.
Perhaps the move to DEXT drivers by all of the current interface manufacturers will make this issue with Steinberg products go away. I’m skeptical but happy that my setup is working once again.
Fire away with questions.
How is the performance with small buffer sizes? External clocking is OK?
IME, aggregates worked fine for a bit, then not so much, then fine again etc. depending on your version of drivers and MacOS.
Let’s hope that moving to user space solutions will give more stable results that will last for a couple of MacOS versions.
I think I have my buffer set to 128 samples at the moment and it’s working fine so far. Haven’t tried anything lower just yet. I have a 3-interface setup (1 x Lynx Hilo and 2 x Aurora(n) units) in the aggregate. The Hilo is clock master and I have BNC clock cables going from it’s clock out to the first Aurora(n) and then on to the second, so there’s really nothing for the computer to do with clocking other than the application passing on the current sample rate to the Hilo and the Aurora(n)s follow suit.
For me, aggregate devices stopped working with Steinberg apps on macOS 11.x Big Sur. All apps I have from other manufacturers worked fine. This new beta driver from Lynx gets me back to being able to use aggregates for the first time in almost two years.
Yes after using Cubase for 20 years… no more aggregate device support. It is the end of the road - couldn’t recommend it to any friends and colleagues. Over to Logic Pro.
Steinberg shot themselves in the foot with this.
Using the Aggregate Device is not recommended for any serious work because of synchronisation missing.
For any serious work? Are you kidding? I have 72 ins/outs in my studio because I track things like drums & percussion. No way to do that on a single interface.
And secondly, calling out a synchronization issue is misinformation. My Lynx Aurora(n)/Hilo units sync clock amongst themselves with BNC clock cable - absolutely nothing to do with the aggregate device itself. The aggregate device simply accumulates the channels into a single device. I do set a clock master which is my Hilo, but that’s only because the DAW/software needs to tell which interface to change sample rates. The other units fall in line.
Read the background in this post. It is extensive and I’m finally in a working configuration again with really zero help from Steinberg.
What was your work around… agree it is poor from Steinberg not to let us know that was going to happen
Lynx released a new driver compliant with the new macOS Audio Driver Kit model and aggregate audio devices started to work with Steinberg software again. I’m on the latest macOS Ventura 13.1. Note that all other software I use (Pro Tools, Ableton Live, Omnisphere, etc.) worked with aggregate devices this entire time using both the old KEXT driver and the new one. The problem was always Steinberg-specific for me.
Ah lucky for you, I use an apollo, a apogee symphony mi1 and motu , 3 interfaces and can’t get audio out of them… logic works great…but when I updated Cuba’s to v 12 it just stopped.
hi. i have a some question, if cubase 11 has no more available aggregate device, so what’s version of cubase / nuendo still had a available aggregate device choices in the driver setup?
I’ve always been able to select an aggregate device in Cubase once set up in the macOS “Audio MIDI Setup” app, it’s just that all Steinberg apps stopped passing audio through an aggregate device when I upgraded to macOS Big Sur 11.3 with Cubase 11 almost 2 years ago (see original post in this topic). Everything worked on macOS Catalina 10.15.x and prior for me before the upgrade to Big Sur.
Hello, I already wrote this here before… we use Cubase 12.0.30 or 50 under BigSur and Monterey with six audio devices (4x MOTU + 2x RME = 240 channels) as an aggregate device and so far there was no problem and everything works for us (MacMini M1 ). Perhaps the problem is not really with Steinberg, but in the drivers of sound card manufacturers. j&r
