Since Cubase 7.0x days (which I hated, went for a long time to Reaper thanks for all the bugs and quirks that were in it…) we are stuck with a 2 lined, 3 pixels width cursor in the arrangement window.
I have the pleasure to use again with 10.5.20 the event transparency setting (labelled now as ‘Event opacity’), but I still have a problem using this over-width cursor with its two vertical lines surrounding a black one. As the cross-hair cursor can be set exactly as needed in the preferences (both in width and color), why not allow the same settings for the project one ?
