Enabling midi recording in Cubase 12 instrument track

I’m receiving a midi signal from my midi controller keyboard in Cubase but when I push the record button on the track it goes dead and nothing is recorded to the track. I’m stumped.

Hi,

Which MIDI Input do you use on the track, please?

How is the Preferences > MIDI > MIDI Filter > Record setup? The default setup is to filter SysEx data only.

How is the Preferences > MIDI > MIDI Thru Active setup? By default this is enabled.
