BillyT you rock!
I have been playing around with your new tuts on dynamic content and the volume slider that were just added here recently. I was trying to do something almost exactly like this on my own but I wasn't sure about the loop part. I had coded something that was close but wasn't working...then I searched and found this posting...whew...perfect answered my questions.
By the way your tuts are awesome. Written in a way that is easy to understand and modify...plus they are in MX on OS X! Thanks.
