Midi issue


I recorded classical piece using BBC orchestra. Worked great. Next day no sound but one little piece of oboe..all the midi notes are there? no sound. All other song working, it just this one. Did i hit a wierd button? nothing is muted. Even tried resetting bbc instrument for a few tracks. Any ideas?
I have this occasionally in Cubase. The problem I found was that for some reason the samples actually didn’t load completely. In my case closing Cubase wasn’t enough, but shutting down the computer and starting again did work? I’m sure you’ve tried this though. Spitfire are really good if you try problems on them, by the way.
