Should Fade In and Fade Out Times Be Respected w/ Function Percentage Adjustments?

[ohbcIT]

I am attempting to control a slider on the virtual console, bound to a function to control house lights. I have specified a fade in and fade out time for the function of 5 seconds. I am able to control the slider over MIDI to adjust the slider and control the function.

When the function is off and I set an initial value, via the MIDI intensity for the appropriate note, the fade in time seems to be respected. If I provide an intensity of 0 the fade out time seems to be respected.

However, if I make and adjustment after I have set the initial value, let's say from 50% to 90% - neither fade in nor fade out seem to be respected and the adjustment is immediate, which can be jarring to the audience.

Is this expected behavior? I was hoping to have adjustments to the same slider / function, via MIDI be smooth.

Thank You,

Is this expected behavior?

If you Start a Function the Fade In is applied, when you Stop a Function the Fade Out is applied.
When you change the Level of a Function while it's running, you do not Start or Stop the function (so No Fade In or Fade Out should be applied ).

I was hoping to have adjustments to the same slider / function, via MIDI be smooth.

If you follow the logic, you need to create specific Functions that change the level.
In your example if you want to smoothly change the level from 50% to 90%, you need to create 2 scenes (....... level 50% and ........ level 90%) and make your Level Change by turning one Function Off and the other Function On.

A more flexible solution would be to use two versions of the same scene (...... 1 and ..... 2), put them each in its own frame and give them both its own Submaster.
This way you don't need to create a whole range of scenes for all the different Levels you want to use.


If you are familiar with Loopback, you could also attach a Loopback Slider in Relative mode as External Controller to the Slider that controls your Level.
Create some scenes for this Loopback Slider:
- Level Up - Fast (DMX value 147),
- Level Up - Slow (DMX value 137),
- Level Neutral (DMX value 127),
- Level Down - Slow (DMX value 117).
- Level Down - Fast (DMX value 107).

Create Flash Buttons for those Scenes and give each button its own Midi Note as External Controller.
Now you can change the level with Up Down buttons from your Midi controller.

Remarks:
- the DMX values mentioned are just examples, you need to experiment a bit with that, to find the values that feel fine for you (in relation to the Sensitivy you did set in the Input Profile for this Loopback channel).
- instead off Scenes you could also make use of Sequence in Run Once Mode.
This way you cannot use Flash Buttons any more, but now you have the possibility to add those Sequences to a Speed Dial to control the Run Time dynamically.

Thank you for the explanation and the thorough answer. I will experiment further.
