OK I may have inadvertently done some thing in settings to cause this. If I open the midi key editor, with a vst instrument assigned used to be able to click on the notes of the vertical screen key board and hear what the note would sound like on an instrument track assigned to a vst. Also if I hit record, and set up quantise, I could click the screen keyboard and they wouldbe recorded. Now that doesn't work. I can still hear the notes if I click on the grid where they have been inserted or if a add a new note. Can anyone tell me what to look for to get the vertical screen keyboard working again?
