Fades

 

The fading definitely doesn't seem linear.

 

I also copied the same test sequence over to some channels on my 1.14 controller so I could watch them together, and it performs exactly the same as the 1.13 controller.

 

The exact reason isn't the power requirements though.  In the most basic circuit design with a way oversimplified explaination, it has to do with the fact that the "perceived resistance" of the LED is not fixed as it is with an incandescent.  As the current changes, so does the resistance that must be used in ohms law calculations.  The controllers are designed to alter the overall power going into a fixed resistance, not a varying one.  The result is a non-linear gamma curve.  Add to that the fact that some LED vendors are now using voltage doubler circuits and other capacitive devices and the exact shape of the gamma curve becomes even more complex.

 

The only good way to get a linear fade out of an LED is through current regulation on a DC circuit.  Firefly is a good example of this.

 

Now back to the topic at hand... we don't even know if the OP has LEDs...

 

I do know D-Light has been working on numerous fixes to the ramp timings, so this might be a firmware thing.  The ramp calculations in Aurora are the correct ones.  I've noticed the same effect on Firefly though when helping in the Red to black through yellow thread.  It might be possible to add an option in playback preferences to "pad" the ramps some, but I suspect the option would look really bad on LOR or hybrid LOR/D-Light networks.  I will look into this.
