Hi,

I am curious if there would be a way to send messages to objects when a patch is being closed down. Similar to closebang but works when Pd is being shutdown as well.

I have an Arduino controlling Leds with PWM. The PWM frequency is set by my patch. Is there a way that when the patch is being closed somehow to automatically send a "0" message to the object setting the PWM.

I want to do this so that when the patch is closed the Leds all shut off. Otherwise they will stay on and there will be no way of shutting them off without opening the patch again, setting them to off and closing the patch.

Your help is appreciated, thank you

Daniel

Thanks sebfumaster, do I need to be on Linux to do this? Can I do it on Mac?

I don't understand how to get this working it seems really over my head, would anyone mind explaining how to get this working in a patch? Do I need to do some compiling?

Thanks
