Only some instruments playing in older files


I’ve been using Cubase happily for years, but today, I’ve tried to open some older work files and the instruments aren’t all playing, even though the recorded data is there, and there’s a sound through the system on the correct instrument setting when I hit a midi key. Nothing is obviously muted, and it’s happening with a number of files.

Anyone know what it might be?

Welcome ! :slightly_smiling_face:

Are you sure that the instruments involved are the same, routed the same way and with the same MIDI channels ?
Another thought : some VSTis that were bundled in Cubase years ago no longer aren’t. I don’t have their name in the mind right now, but it’s somthing to check, maybe…

Hello! Yes, I think so… and the VST’s still patch through fine on the midi.
