Um
I disagree with that (the SNAP feature part).

There are many times when an audio track phrase is not aligned to snap ...
Just sayin'

If it was created with MIDI and quantized what you say would be true, but for a lot of my recordings the only MIDI is the click track.
It will likely help to know about that feature, but at times it may cut off a bit of what you want!

The key (to me) is making sure to pay attention to the numbers in the from-thru section when cutting/pasting/copying and make sure to use the same start number as the paste point.

Example -you want a phrase from measure 10 copied to measure 27-
copy the phrase (example 10-1-112 thru 1-4-111) making sure to paste it at 27-1-112 (the exact same time in the measure so it doesn't lose the timing and feel).

The issue is that it depends on exactly what it is you want to use; may not always be full measures.
If it IS full measures or beats then using the SNAP or even the Bars window is convenient.
The Bars window makes copying sections of a song (multiple tracks) very easy and convenient.

I do not work here, but the benefits are still awesome
