Some basic questions, please help

How do I pause a vocal recording seesion in cubase elements 13?
How do I erase a portion of vocals without erasing the whole thing?
How do I also monitor a vocal recording with studio monitors while mixing it?

Hi and welcome to the forum,

Click the Stop button on the Transport Panel.

Use the Split tool to split the Audio Event into multiple events. Then delete the unwanted Audio Event.

What do you mean? What can you monitor already? What are the other tracks type?
