Oxygen 25 (maybe other midi controllers?) not working

Hi to the forum,

Using CUBASE 15, Oxygen 25 midi kbd controller is dead. Is identified by CUB15 but there is no activity at all.

With CUBASE 14 works perfectly. Also with HS in standalone mode is totally ok.

I am using macOS 10.15.7 without any driver installed. As said using CUB14 in the same computer everything runs smoothly.

Any changes made?. Something to previously take into account?

Thanks in advance for any help

Can you post a screenshot of your MIDI Port Setup in Studio Setup? Have you tried clicking on the Monitor in there to see if there’s any activity?

Here it goes. As you can see Oxygen25 is identified but not working.

Also checked the OnScreen Kyb is not working!!!

When you click on the first MIDI icon in the Monitor column, it pops-up an Input Monitor. Do you see any data streaming in there when you touch the keyboard?

Just a simple guessing:
At my place my USBconnection loose track of my midi keyboard for some odd reason. I just turn the power off on my midicontroller while Cubase running, and on again, and ‘pooff’ it gets contact and ok.

No activity at all on MIDI Monitor. Done as you said and also via MIDI Insert in the MIDI channel.

Also, as said before, On Screen Keyboard works only in a MIDI channel but not on a Instrument channel.

Really strange because everything works fluenty on CUB14.

Looking for the bug…

Thanks for the reply. Of course already done a hundred times with different settings. plug-in, plug-out, on/off, fresh restart of the mac …

Could be something related to MIDI 2.0 …
