CC121 and Mac M1?

Can I hope for connectivity…?

Any info on this? I’m going to be getting M1 Mac soon and would like to buy the CC121 as well, unless it’s not going to be supported.


Got the MBP with Apple Silicon and used it with Cubase 11, the CC121 didn‘t connect yet. Perhaps I made a mistake with the setup?! It‘s been a long time, that I connected it in the first place on the old machines (MBP from 2013, still running nice though). Any Ideas?

There is no support yet. And who knows when?

I just received my CC121. It seems it doesn’t work with my Mac M1 / Silicone / Big Sur.

  • I’m running Cubase 10.5.30
  • I installed TOOLS for CC121 V1.7.7.pkg
  • the “Cubase ready” button on the device is blinking
  • I see the CC121 in the device list, but when I click to add it, it isn’t actually added (video:

I bought the device since I believed it is supported, or soon will be supported on Mac M1:

Steinberg, please advice!

Thank you.

I have exactly the same issue on a M1 Mac Mini running Big Sur 11.3.

  • running *Cubase 11.0.20
  • installed TOOLS for CC121 V1.7.7.pkg
  • “Cubase ready” button on the device is blinking
    Cubase sees it in the devices list, but when I try to add it, it does not get added.
    The device worked perfectly on my previous computer, so Im pretty sure that it needs an update.
    Steinberg team, any help?

Steinberg released the latest Yamaha USB-MIDI driver (V1.5.0): Yamaha USB-MIDI Driver V1.5.0 · 4.7 MB

It has to be installed on top of TOOLS for CC121: TOOLS for CC121 1.7.7 · 4.7 MB

I’m confirming everything works for me after installing the driver (Cubase 10.5.30 on Mac M1 with Big Sur)! :slight_smile: :+1:

Same for me, now it works again. Thanks Steinberg for the driver update!
