When I play my Arturia synths directly all MIDI controllers like modulation wheel, work perfectly. However in Cubase 12 the mod wheel is controlling other parameters and I can’t record them either.
In older Cubase versions it seem to work flawlessly.
I have no idea. I use Cubase for 30 years now and never encountered this kind of problem. Recording a midi controller used to be easy in the Atari days!
MIDI Remote is here to be able to control Cubase from your hardware. I don’t think this is what you are searching for. I was asking to make sure the MIDI Remote doesn’t filter the MIDI Messages.
Could you try in Cubase Safe Start Mode > Disable Preferences, please?
