Hi everyone,

Hi have one scene that I would like to activate and deactivate by MIDI - switching power on/off
I am using the trigger (0.5) and wrap (2.0) as explained here: viewtopic.php?p=4407#p4407

Now, I would like to have it activate with a fade in, and deactivate with a fade out.
Is there a way to achieve this? I have tried many different possibilities, and have come to a point of such confusion that it is even difficult to retrace my steps.
My most hopeful attempt was to create a scene fading in, and a duplicate scene fading out, and activating those with different MIDI notes. The problem is that after trigger the OUT scene, it remains with power on, and I wanted to have turned off but ready for another triggering at will.
I hope you can understand the situation, thanks for your help.

Add some smoothing...

Thanks Sadler, in your solution I believe that whether the scene would be visible or not, it would anyway still be running.
This is something I wanted to avoid not to use up my PC resources, and therefore I was working with powering on and off.
This screenshot shows what I'm trying to achieve - again, with fade in and out on triggering.

Yes, the scene or media would still be running. But you could also have a power off on the scene that activates when the fade is complete. Sync the two nodes using a global.
Also, depending on your exact use-case, a multimix may work for you. That will turn off inputs that aren't being mixed.

Thank you very much Sadler.
Based on your previous answer I got to work and managed with the following combo, although yours is probably more elegant and efficient.

Thanks again! Was stuck here for the past 36h
