I recently upgraded to Dorico Pro 2 on OS X El Capitan (10.11.5), and while most features seem to work normally, playback has been having some strange errors. When I try to start playback from the beginning, it starts somewhere in the middle of the piece. After a couple restarts, I can eventually coax it to start from the beginning, but it still won’t play where I would like for the rest of the session. The playhead is moving, however, it’s not moving at the same position as the music being played. When I try to start playback from a specific location using the ‘P’ command, it always starts towards the end of the flow regardless of what location I’ve selected. I can’t find any consistent pattern between where it’s actually playing and where I want it to play–it’s not consistently 20 measures ahead or anything like that, it’s just always farther into the piece than where I’ve selected. I’ve already tried deleting the VST instrument folder in ~/Library/preferences, to no avail.
Any thoughts? I would rather not update from El Capitan if possible, but I know that that’s eventually going to have to happen.
