Im using this on OSX Monterey on intel with Cubase pro 14.0.10.
It installs and get starting with ease. It is a very good companion for a mix surface. (I use Avid). This is a fairly new product and the software is not ready yet. The DAW integration seems OK, it introduce a GUI lagging in cubase itself, it might be the unit or it might be Steinberg to blame. And the firmware on the unit crashing very often. The easiest way is to select Q-control and do some channel switching from the unit. It wont take a long time before it resets. (on firmware version 1.1.9 and earlier)
Pros: Using steinbergs new javascript interface for cubase.
Cons: It requires a lot of privs to work. Security concerns since it reads your keyboard (qwerty, not only in cubase) and could steal your passwords. Im not saying that they do, but if they get hacked you will be hacked too.
Conclusion.
At the moment I do not recommend this for cubase. Wait until the software is ready.
Update to 2025.03.01 software release 1.1.11 and still fails on cubase 14.0.10
Update 2025-04-13. Software release 1.1.19 stability issues seems to be solved. A bit sluggish but works as it should.
