1. most likely this is the culprit:

class_addmethod(arp_class,
		    (t_method)arp_bang, gensym("bang"),
		    A_DEFFLOAT, 0);


with this code you say that arp_bang() expects a float as an argument.
but arp_bang() does not!!
(and btw, you already have added a bang-method with the class_addbang() 
for arp_bang()


2. it might be a better idea to use "static" for all functions that you 
don't want to export (all but the _setup() function(s))

3. pd-dev is the list... :-)
