CC121 suddenly dead

My CC121 stopped working when I updated to Cubase Pro 9.5.41. (It doesn’t work with Mac OS High Sierra 10.13.5, or with Mac OS Mojave 10.14.1) The Steinberg downloads page for CC121 driver shows the “latest” CC121 driver was released way back in JAN 2015! So I don’t know what to do. Is their a new driver for CC121 on the way?? Does CC121 work with the new Cubase Pro 10? I don’t want to go backwards to an older version of Cubase Pro.

I called Cubase support and they don’t know what to do either. Any suggestions?



Yes, CC121 works with Cubase 10.

Are you sure the HW is not broken? Or an USB cable?

I went ahead and updated to Cubase Pro 10 and also to Mac’s newest OS: Mojave v 10.0.5…and I can report that the CC121 is is indeed now working fine! Note: I did have to re-load the CC121 driver however, after updating to Cubase Pro 10.
Then it worked

Correction i meant to say i’m running MAC OS: MOJAVE 10.14.1, and Cubase Pro 10.0.5. and: the CC121 is now running fine, AFTER re-installing the CC121 driver (the most current of which is dated way back to Jan. 2015 on the Steinberg site, but it DOES work! :slight_smile:
