What does the little red triangle on the Ruler do?

About once every 2-3 years I will see a little red triangle on the Ruler. You can move it about with the mouse, but there’s no tooltip so I have NO idea what it does.

What does it do?


Interesting! Do you have a screenshot of that by any chance?

Punch in / out markers - you’ve obviously accidentally activated it on the transport

Thank you.

It may seem weird. But in 20 years with Cubase I’ve literally never used them.

I wish things like that had tooltips.

Me neither!

Bit of a throwback to the days of tape, and pretty much unnecessary with pre-record and other DAW tracks I feel.
