Question (or Task)

How can one have an envelope running in reverse with just a simple toggle? I expect a behavior that reverses the timing of the envelope, running from end to start and not a (1 - Output of Envelope). It should also be done with an ADSR and not the GraphicalEnvelope, since I want to have hot parameters.

Solution(s)

One idea would be to use an ADSR envelope with the AttackTime parameter set to

((1 - !Reverse) * !Attack s) + (!Reverse * !Release s)

and the ReleaseTime parameter set to

((1 - !Reverse) * !Release s) + (!Reverse * !Attack s)

This causes the ADSR to use !Attack and !Release for the attack and release times when !Reverse is not on, and the reverse when !Reverse is on.
