I'm new to Pure Data and have a very simple problem I need to solve!

I have 2 bang messages, but I need to create an object that will only send a bang if there is a bang on both inputs at the same time. I have tried using a logical and (&&) but this doesn't do what I want it to!

Please help me!

Thanks,

Matt

2 bangs will NEVER happen at the same time. there will always be at least a tiny fraction of a second between each one. even if you bang them progromatically, one of the bangs will be sent before the other one.

so, what you need to do, is to define what you mean by 'the same time', by giving a threshold for the minimum time between bangs that will count them as occurring simultaniously.

hopefully the attached patch will do what you want. i have set the threshold to 10ms by default, but you can change that if you need.

cool thanks!this works great!

i also need a way to only send out a bang only if the left input has recieved a bang. if both are a bang then no output, if right only has a bang then no output.

any ideas?

to explain this is for using a rock band controller as a midi device!

if you look in my patch, there are two sets of 5 buttons, he lower buttons at the bottom of the neck, and the top buttons higher up the neck. when a lower button is pressed, only one of the coulours is toggled on. when you press a top button, one of the colours is turned on as well as the first grey toggle.

i need a way to be able to tell the difference between top and bottom buttons so i can send different midi messages. also, messages should only be sent when the strum bar is pushed with the buttons (strum bar is toggles 9 and 10 along)

i think you should look at [spigot]
