I loaded inside cubase 8.0.20, a project from cubase 7.5
One track is transposed 1 octave down.
When I open the midi editor, the bar is in the right place, if I play the note with the keyboard
it shows I play the same note as the bar. But if I click on the bar the note is 1 octave down.
The only way I could use to surround this problem is to transpose the track.
I have about 18 tracks, only one behaves in this way.
If I created a new project with one track, and the same VST with the same patch, everything is correct.
