Where's the setting for "Do you want to create a midi track"

When putting a new VST instrument in the VST instruments window, It asks “Do you want to create a MIDI track”. I must have checked that said “don’t show me this again” and checked “no”.

I want to reactivate it but I can’t find where to do this. Looked in Preferences and elsewhere but couldn’t find it.

Anybody?

Thanks!
