Grid Fade In/Out

[Zorpiedoman]

When I set the fade in or fade out for a grid, it seems like all attributes are fading in or out at the same time.

If I am fading in a simple, single, solid blue light, It starts out as a shade of white and goes blue.  I'm guessing this is because the saturation is "fading in" also.  Is there a way to lock individual sources so they are not affected by the grid fade in/out?  I would lock my saturation and my hue so that only the intensity is fading in or out.  For that matter my fixture has a dimmer and I would lock everything except that.  that way when the light comes on it goes from a dim/dark blue to the full blue color

thanks!

You can put attributes in different grids if you need different fade times.

You can also set the fade on the source. The way to do this depends on what the source power is linked to. For many inputs, you can specify the fade time. For even more control, edit the formula and use the fade function.

[Mathieu]

You can also lock the saturation and hue attributes. Select all hue attributes and then set the min&max to the same hue. Click on the middle of the hue picker to move both min&max at the same time.

Make sure to look at the 1st video tutorial to learn more about attributes.

Found an even easier way...

If I just assign a pallette to ALL the RGB attributes of a fixture they all remain fixed.  Then the fade ins and outs are perfect.

Good idea to use the color palette!

Now my final task is figuring out how to assign midi channel messages to my grid that turns all my "color grids" on and off.  Gonna go watch a video.

Are you using note or cc messages?

[John Shelley]

Either.  I've made a bunch of grids for each "scene" in my show.  Then I made a single 1x100 grid with activation attributes for each scene-grid.  One power source and by setting the X coordinate, it moves to a scene to turn it on.  Works great using my mouse.

Now I just need to understand how to assign anmidi note or cc message to that source th change it's value to jump around this grid.

If you want to use a CC message, you can use something like this for the source's x slider:

xtopercent(midi.controlraw(1, 1))

So if the CC value is 0, the source goes to the cell position 0, CC value=1, position = 1, etc.

[John Shelley]

didn't even need that.  Just chose CC47, (what I'm sending) and the value changes the position.  I had to make my grid 1x128, of course but it WORKS!!!  My system works perfectly!!!

*doing the happy dance*

Great idea to resize the grid! I think it needs to be 127 though since midi values are from 0 to 127.

[John Shelley]

...which is 128 positions.  :)

I'm so psyched, this works perfectly for what I need!

You're absolutely right :)

[John Shelley]

So help me out one more time if you could...

I want to send MIDI control messages to alter the fade in and face out time for the grid.

I'll send the message on CC49 as follows:  

0-50 = Fade In time in tenths of a second

51 = Fade In Linear

52 = Fade In Exp

53 = Fade In Log

54 = Face In Sig

60-110 = Fade Out time in tenths of a second (subtract 60)

111 = Fade In Linear

112 = Fade In Exp

113 = Fade In Log

114 = Face In Sig

So, if i want the fade in to be linear for one second I would send two messages: 51 then 10

And if I want the fade out to be Exponential for half a second I would send two messages: 65 then 112

What would the formula look like?

Is this possible, or am I understanding this wrong?

Looks like this is not possible as the fade function is an action, not a setting... (I think)

fade(2,100) has the value go from 0 to 100 over two seconds when the function is activated.  

I was hoping that I could send the midi message early to kind of say, "ok next time I activate this grid, fade in over two seconds.... and it would do that every time until I changed it.

Hmmm.

[Mathieu]

I think I see what you want and yes, it's a bit tricky to use the same CC message to control multiple things. But it's possible with the latch function. Something like:

fadein(latch(midi.control(1,49) <= 50,  midi.control(1,49)*0.1), !grid.onactivated)

Each time the grid is activated, the fade in will execute. The fade time is updated each time the CC49 message value is <= 50. 

[Mathieu]

...but it would be easier and cleaner to use different CC messages, one per parameter you want to control.
