I use the split window in every project to hold my Marker and Arrangement tracks. Cubase doesn’t always recognise that you have clicked in the other pane and so - if you’re not careful - carries out the operation in both.
To try this:
- Split the Project Window (it’s the [/] button above the r-h scrollbar).
- In the split, create (e.g.) an Arranger track and create an event on it.
- Now go back to the lower pane and make sure you have a track and/or events selected in it. As if you had been working normally.
- Now select the event in the upper pane you just created and change its colour.
Any event selected in the lower window - or entire selected track if no events are selected - changes colour too. This happens with other commands too - such as delete! Thankfully, the changes in the lower pane can be undone with Ctrl-Z, leaving the changes in the upper pane. If you notice in time.
How many times has this caught me out?!
The only way I’ve found to guarantee that the action is only in the upper pane is by selecting the track (Arranger in this example) first.
Can this be addressed so that the pane last clicked in - whether on a track, event or empty space - become universally active and the other universally not.
