I'm using pd to receive a value which is constantly given from a csound program. In my pd patch im using [r filelen] which gets the length of a audio file. I send this value to adjust the "loopend" of the sample I want to playback. However if I keep [r filelen] attached to the number object, It flicks very quickly back to the original loop end when I want to make adjust meants. How do I take a value thats has constant out put store some where and then send a bang perhaps when I need the value?
