I was going through the autopttr references and could not under stand this one. If some one can explain this to me I would be grateful, since I'm not sure what the dirty word means ;)
"The word dirty, followed by a 1 or 0, enables or disables the patcher-dirty flag. The default is 0 (disabled). When enabled, the autopattr object will dirty the patch whenever its state changes."
What does it mean to dirty a patch in this context?
