Made one observation this morning of a different behavior in the mixer when changing the volume with the mouse vs. changing the volume from a mapped controller:
When I change the mixer volume of a mixer channel with the mouse let’s say from -5 to -10 and switch to another song and then back to the song in which I changed the volume, the changed value of -10 is still there.
When I change the mixer volume of the same mixer channel in the same song with a mapped controller from -5 to -10 and switch to another song and then back to the song in which I changed the volume, it reverts to the original value of -5 , likely from the last saved state.
Not sure if this is “by design” or a minor bug (and which of the two is the intended behavior).
