It’s an interesting feature.
And it seems you can also layer with it.
But as an example. You have a snare (Track 2) and another track (Track 3) with a channel strip configured as a side chain on Track 2.
If you freeze Track 3, even if Track 2 is playing, the resulting audio track is empty.
It is not what you can do with resampling.
Anyway, thanks for the explanation, Lars.
