Hi!
I would like to ask for a readout of what instrument is missing. Recently I worked on a lot of older sessions and I encoutered a lot of problems recalling the sessions. The biggest problem is that when you named an Instrument Track “Lead” for example, Cubase only says Instrument “!!!Lead!!!” is missing (when you don’t have it installed any more) and you have no idea which VST it is actually looking for. So please make it possible to know which VST instrument it is actually looking for.
I’ve just recovered from a system disk failure and have only reinstalled my Steinberg stuff, so I’ve got a ton of missing plugins on most (all?) Projects at the moment. However if I open one of those Projects it displays all the missing plug names and can even export the warnings. I take it you don’t see it?
I hadn’t thought that saving might inhibit the warnings. So I made a copy of an old Project & opened it which generated the warnings. Then I saved, closed & re-opened it. Still got the warnings.
