Cannot connect to coremidi


I got the message of Nuendo unable to connect to CoreMIDI after I installed CC121 all other midi devices I have worked fine. Sometimes CC121 also works but if I shut down Nuendo and start it again it gives me this message of being unable to connect to CeroMIDI.

What is the problem with that? Ableton Live and Logic can perfectly see all midi devices.

I just started getting this message. I re booted…same again :frowning:

It helped me by running Midi Monitor once the systems starts. its always in background and no more messages. Strange solution but works:)
