[ANSWERED] ​Triggering opacity of a image with a piano



  • Hello

    I'm quite new to this software, but i heard great thing.

    For my first project i would like to use a midi keyboard to trigger the intensity on a image with velocity, and then let it slowly fade to 0 opacity.

    I've manage to have the keyboard trig the intensity, but it stays on until i press it again.

    Any cues?

    thanks

    See my attached image. You can trigger the intensity of the projector directly with the "note on watcher" actor and input this value also into the "envelope generator" actor. With the trigger delay you can define the time when the envelope generator triggers to fade out to zero. The rate time of the "envelope generator" defines the fade out time.

  • @michel Thanks! exactly what i was looking for!

    Now, do i have to do the same for all my different images, or is there a way to have the keyboard trig different images in the same setup?

    If you want the same trigger to do the same for multiple projectors then you can directly link them; you can have more than one connection from the same device. 



  • Not exactly. I want my different keys to trig different images. Is it possible to do it with only 1 note watcher? and automate it?

    @pirgil

    If you have different movie players/projectors and you want to trigger them depending on the note you are playing, you need the same setup for every key. The default for the note on watcher is that its listening to every note. If you press a key you see on the output side of the note on watcher what port/channel and pitch was triggered. Type these numbers on the input side of the note on watcher then it will only listen to exactly that note in future.

    for easier midi assigning you can also use the midi learn user actor: https://community.troikatronix...

  • if you are only playing one image at a time, you can automate the system with one Note On Watcher - you need to load a series of image files into your bin and change the reference number in the Picture Player. The Limit-Scale Value actor is for assigning the range of keys to the range of images.
