I have a song recorded in which I used Play vst (QL Pianos), worked fine until today. Now when I open the project i get a message “missing ports” and then “unmapped”. After which the Play vst does not appear in the project. I went to devices, instruments and tried to reload Play and it couldn’t do it. Tried vst connections, rebooting, restore to an earlier time (Windows), resetting my interface… Nothing. I started a new project, loaded Play, and it did work there. Help?
