great @oid, it's working well now! (the one updated from https://forum.pdpatchrepo.info/topic/14537/poly-for-anything/16 because I think spoly3.pd was faulty)

Thanks also @jameslo for this very nice patch! It's more than I need but it is very useful.

I really think this kind of multipurpose abstraction should be shiped in puredata, along with [clone] to fullfill basic need and be consistent with Miller clone logic.
