Hi,
I've noticed that drawing a similar curve as and Event Fade on the Volume Envelope yields vastly different results. The Fade Out on an Event is gradual and natural, but the same shape on the volume envelope is incredibly aggressive and sucks the volume down way too fast in comparison.
On all other DAW's I have used, I have not noticed this and had always found it very easy to move (the equivalent of) an Event Fade to the Volume Envelope with no discrepancies.
