Have just started a new project from scratch, using Play from EastWest and a few Cubase plugs.
While editing the drum track (first double-click, and then undock the drum editor, I discovered that undo no longer works. I see the events in History, but can’t go back.
This is potentially catastrophic if it happens on a real project, not just something I spent an hour creating just to play around with Cubase 9.
Can’t reproduce it as such, but the history remains frozen in this project.
I just posted something similar. I create a VST synth, start recording. When I hit stop the midi events are drawn but I can not double click to edit nor resize. And: Undo/history is no longer working.
My workaround: Duplicate the VST Synth track, then delete the troublesome track.
The new events are now editable. However history is still not working.
