    Default Create strobe effect in livepro?

    I'd like to create a strobe effect in LivePro so that I can hotkey it and apply it to whatever effect in a track/zone is running for live punctuation of effects. However, I can't seem to see where i would modulate the brightness/intensity like that.

    I've looked in key effects at blanking masks but that just seems to draw the frame, colour effect just seems to do cycling of the blanking, and regular effects only have positional parameters available.

    About the closest I've come is a key effect using colour, saturation, lightness but UI can only get it to fade rather than step as there isn't really a suitable waveform (needs square really)

    Can anyone help?

    You could make a color cycle that does that (by setting the color to black for the whole image part of the time), but I can't think of a way to do it without changing the color of the animation.

    I'll take a look, I only have 532 projectors anyway so colour isn't really an issue for me..




    Yep, seems to work although the preview window doesn't really show it working at the correct frequency. I guess it'll display fine on the projector but it's tucked away at the moment so testing properly will have to wait.

    You might be able to do it with the RGB Oscilators... Set the Speed and Frequency real fast...

    Can't guarantee it will work but worth a bash...

    you can also create a new colorcycle with a brush for the entire gradient cycle, create 2 colors like black and white and lower the brush frequency as low as requered.. than you can apply the strobe on all frames.

    Good question, and that would be awesome to have a HOT key, that would strobe whatever was being projected, sounds like something Pangolin would have to install though....

    Why would Pango have to install it?

    It's just a case of creating the colour cycle effect in a cue, and assigning a midi key to the cue. Choose the tracks you want to effect and hey presto... Only thing is it would overwrite any other colour cycle effect in place at the time, but for single colour thats not too much of a problem unless using blanking masks.

    Shame it doesn't work like my lighting desk tho, that can be set up to have different behaviours. So you could have it like an LTP channel where it reverts to the previous effect when the current one is released.

    In fact there's so much about my lighting desk that I like and keep thinking 'why can't my laser controller also do this?' Ironic then that my desk is made by the people who did the Chameleon laser controllers

    You can also create a new key effect, add an color action "rgb levels", and make the timeline color start at value -255 , second step, value 0.

    I have added a simple example.. incomplete.. but i think you will get the Idea. Stil needs finetuning..

    I'm jss sayin....
    I'd like to have a simple strobe button right next to the stop button, VS.
    Having to program color cycles, map midi, and still end up with having messed up the original colors..

    Now that I think about it, I would just have to modify the electronic interlock circuit on my projector, with a simple circuit that would quickly switch on/off

    its not a pre-programmed dmx laser your playing with
    When you use livepro , you have the most sophisticated live software availeble, with a huge learning curve. But if you master the program you can do unbelevible things..

    Pangolin already made the function possible, but you have to be creative to create your own workspace for that. My guess is that pangolin did not include that, cause its relatively simple to add it as an effect. All major functions outside your workspace, like scene cross, need separate buttons to assign it.

    But you can always ajust 1 tile specificly to a midi button. Its all in there
