Home: Isadora: User Patches, Tips & Tricks: How to trigger something once...

skulpture User May 20, 2008, 6:04 AM Post #1 of 9 (3707 views) Shortcut How to trigger something once... Can't Post I am receiving OSC triggers from EyeCon. The trigger sets off the envalope generators in Isadora, it all works great but I was just wondering how I can make a 'gate' or 'switch' that allows only one OSC trigger an then ignores the rest. Does this make sense? I want to gate or stop the messages so that the person triggering them does not trigger again by accident. Any ideas? An instant without duration.... www.grahamthorne.co.uk

Connect your osc trigger to the trigger input of a Trigger Value actor set to zero. Connect the value of the trigger value to the on/off input of a gate actor. Place the gate actor in between your Osc listener and your envelope generator. Does that make sense - I should have made a picture or sommat. You've probably sussed it by now anyway. Don't forget to reset the gate actor to on Gav

[In reply to] Can't Post I did try the gate actor but the gate just went on/off/on/off because the trigger was still coming in from OSC. I have figured out a way, its a bit of a poor excuse for a solution. (see attached) Basically I have used a "trigger value - 1" going to a "calculator +1" an connecting that to the OSC channel. Thus once triggered it changes to channel 2 stopping any more data. Its not the best way and I can't use channel 2 now but its working for now.

I'm almost certain that if you send a 0 to the Gate Actor then the gate should never go on. It will go to off and stay there. Trigger a trigger value of zero.

[In reply to] Can't Post Hi Gav, I did read your post yes, but probably read it to fast! Your right it does work, I will probably re-do the patches I made today using the gate actor. Thanks mate.

[In reply to] Can't Post In the past, I've used a pass value actor set to a max of 1 so when the curve hits one, even if a pulse or a trigger is still coming it, nothing passes. There is an integer counter inline before set to stop counting at 2 (for some reason when it's set to 1, it occasionally won't fire properly. Anyway, this is setup so these two actors both stop calculating after 1 pulse for the pass value, and 2 for the IC, to save on cpu (however minimal it is). Actor attached.

[In reply to] Can't Post You can use the MultiBlocker actor with a time of like 99999. That's 27 days or so; not really just once, but pretty much the same result unless your making an installation that will run for a year, etc. Best, Mark - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Mark Coniglio / TroikaTronix Creator of Isadora
