not sure if this is what you want...

Thanks that did the trick!

Hi,

perhaps a bit late, but The sadam Library contains an object called [sadam.empty], which would detect (or generate) empty strings.

HTH, Ádám

Thanks Adam for the suggestion I eventually went for a JS solution as i could combine so many objects (route,prepend,change (for symbols?)in a few lines of code. The more I use Max the more I end up just writing a js for what should be simple things. I don't think max is that good for simple non realtime data processing. Detecting an empty string should be a lot easier than this. It's just a bit messy having to link up a new js file or the time, would be nice if you could 'embed' a js like the way you double click a col object to see some stuff. Anyhow just my 2 cents. Here's my script it's simply to pipe a host into a udpsend object. I can now just have this inbetween my textedit and udpsend object.

var lastHost = ""; function text(host){ if (typeof host != "undefined" && host !=lastHost){ outlet(0,"host" , host) } }
