Cubase Pro 10 with VST Instruments

Hey everybody,

sorry this might be a stupid question but I´m about to surrender.

I create a new Intrument track (like Native Instrument). Then I want to record this instrument…

Do I need to have a MIDI keyboard to get it recorded??? When I use the vst internal keyboard it doesn´t write any midi information into the vst track while recording…

In Cubase 9.5 I didn´t have this problem?!?!?
