Is this a bug or a feature with audio regions?

Question

ok so I have an audio part in a project then copy/paste in a later part of the arrangement and after that change the size of the new copied part with the mouse(dragging from the end of it)it changes and messes up the original version as well. I just recently switched to Logic from using Cubase so is this some feature of having the regions linked together somehow or is it just working wrong?

Answer 1

I found the part that talks about how copy/paste is supposed to work, and it turns out that the manual describes how people want it to work instead of how the app actually works. It says that copy/paste makes a copy (a new region) and the two can be edited independently. Copy/paste is NOT supposed to create a clone.
Unfortunately, the app doesn't work the way the manual describes. Here's the relevant part from the manual:
"To copy a region (method 2):
1 Select the region, then choose Edit > Copy (or use the Copy key command,
default: Command-C).
This copies the selected region to the Clipboard.
2 Set the desired playhead position by clicking on the Bar ruler.
3 Choose Edit > Paste (Command-V) to paste the contents of the Clipboard into the
Arrange. The paste will occur on the selected track at the playhead position.
If several regions are selected, their relative time and track positions are retained. "
"*Copied regions are actually true, independent replicas of original regions. Changes*
*made to a parent region will not affect child copies.*
If you want this type of behavior—where changes to the parent region affect child
regions—make use of the Loop function (see “Looping Regions” on page 329), or
create cloned or alias regions (see “Repeating Regions” on page 324).
*When you copy an audio region, a new region is automatically created in the Audio Bin.*
*The new region will retain the name of the original, with a sequential number added.*
As an example, kickingloop.1 will be the name of a region copy, if the original region is
called kickingloop. A second copy will be named kickingloop.2, a third kickingloop.3,
and so on."
Looks like either the manual or the app is wrong. Hopefully apple will actually read the bug reports and fix the app.
