No midi from dybler2 to cubase12pro

I often dont get any midisignal from dubler2, I try both dubler2 and all midi inputs.
I use channel 1 and 2 as output.
I have same problem with tascam144 and ssl2+
Whats wrong?
Dubler2 works fine.

Hi, can you check the virtual MIDI port is set to ON in the audio device settings? If for any reason the virtual MIDI port is off and doesn’t allow you to turn it on you can follow the steps in our troubleshooting guide here -

If your virtual MIDI port is on but it’s still not working, it would be good to send some screenshots of Cubase’s preferences and we can try spot anything that might be causing this
