Safe the project under a new name!
Assuming you have a constant tempo, make regions from the 8 bars verse and chorus. Now delete everything around and in-between. Arrange the regions to taste.
Thats the quick way.
Alternatively you can copy/paste the regions into a new project. You can save yourself some work, by taking the original project, save under a new name, remove (not delete) all arrange content. Now paste your 8 bars of verse and chorus.
Thats just two of a few dozen ways to do this………..
Have a nice day!
The simplest way to do this is to select all regions that you want included in the file, then click Bounce, and the locators will automatically be at the first and last point of whatever is selected, and everything between locators will be bounced to AIFF or WAV or CAF. You can see the locators' position in the Bounce dialog.
