Hi list, Here's a pd-vanilla subpatch that outputs an abstraction's creation arguments as a list. Just copy and paste "pd arguments" to your abstraction and it should work. It will output a single bang only if no creation arguments are supplied, so you can check whether they exist or not. I offer it as a kind of condensed alternative to Matt Barber's approach that was posted awhile back (which I cannot find at the moment).
