Summary0008411: No midi sound from saved midi region
DescriptionThere is no sound from the midi track that was saved before i open the project. If i make a a new identical midi track (same vst, preset, plugins, untouched audio routing as i always do) there is sound but that midi track will have no sound if i save and re open the project again.
Steps To Reproduce1. Record a midi region with a vst on Windows
2. Save project and verify that the midi region had sound before closing the project
3. Open project and midi region got no sound, the plugin itself won't produce any sound even though master bar is showing sound.
Tagsplugin, VST, Windows

This is also on new PC so it should not have to do with my old PC

Audio produces sound fine but midi doesnt.
I can only hear the audio files when opening this project and need to make a new midi track to be able to hear that midi track only (Old ones still silent)
