searching for a object that will send me bang when the data change from zero to non zero?

funny but searching for help HHH

[edge~] does just that. There's no helpfile for it in Pd-extended, but I posted one here.

thank you mr Maelstorm

After rereading your post, I realized you didn't say whether it was a signal or message data. If it's signal, [edge~] is the easiest way. For messages, you can just do this:

[!= 0]
|
[change]

[sel 1]
