What is the best way to trigger a my sequences?

[jinglejedi]

I am currently piecing together some animations of photos that will move across the screen at various x,y,z, positions. I have figured out how to make the image move using a rectangle geo, (with an image texture) and have the rectangle linked to 3 differnet partial-sine waves that transform into x,y,z values that cause the image to float in and out of the screen at various rates. The only problem is I need a way to trigger each photo sequence as I will be following along with a live narrator. I have a MIDI keyboard I would like to use so I can assign a different key for each photo animation I create.

The wave CHOP has no way to connect a trigger input. What can I use to trigger my animation?

you can use a count or speed CHOP, followed by a lookup CHOP with your wave CHOP in the second input

Right now the issue I have is there is multiple instances of moving objects that need to be independently triggered. When I open my env. and hit play, they all come barreling onto the screen at once. How can I set it up to trigger them one at a time, and non of them start when I just hit the bottom play button.

for now substitute the midi keyboard with a Constant CHOP or an array of Button COMPs
Simillar to a keyboard you would trigger everything manual by either clicking the button or setting the appropriate channel in the Constant CHOP to 1 and back to 0.

Would that help?

The animations play on thier own regardless of whether there is a trigger input or not. It runs as soon as you open up touch. All I am doing is using the reset input on the speed chop to restart it, but obviously that would not work if I have to load it up for a performance live.

Here is a download link with a JPEG image of what my Touch arrangement looks like. (Scroll to bottom of web page to download)

Perhaps that will help.

Hey,

attached is a version of your trigger/speed network that would do what you are trying to do, I believe..

The Speed CHOP will increase by 1 every second when given a channel with the value 1 in it's first input. The second input will reset the speed if given a channel with the value of 1.

Have a look at the wiki page at http://www.derivative.ca/wiki/index.php ... Speed_CHOP for a more detailed explanation.

So if you don't want the animation to run on start up, just have a ll the channels in the Constant CHOP called "trigger" set to 1 as this will reset the speed and hold it at 0.

Hope that helps

Hello Markus,

Thanks for the tip on how to hold back immediate playback by connecting a constant CHOP to the reset input of the speed CHOP. I can now open my project, hit the global play button and it stays in place. Now I just need to figure out the easiest way to trigger it using my Korg NanoKontrol. So far all I can do is hit the bypass button of the constant CHOP in order to initialize the speed CHOP. I have tried various methods but to no avail. I could enlarge all my constant CHOPS and use the mouse to click the bypass buttons one by one, but I would much rather use the MIDI controller to do this. How would you do it?

Hey,

have a look here on how to get Midi going:

If your kontroller is the nano pad...

Actually I have the Korg NanoKontrol. Might get the nanoPad down the road. I like the idea of nice big buttons to hit for a live performance.
