That's correct. Sorry about the cryptic help file, I'll make a better one. > It appears that the tables are correctly allocated by this, but they are > not initialized; i.e. the arrays are created, but the code that fills > them in is not triggered, even though there is a [loadbang] in > [waveTables] that's supposed to trigger it. > > So my question is first, am I even close to using [singleton] > correctly? and secondly, do objects created by [singleton] get a loadbang? They don't get a loadbang, because they are dynamically created. Dynamically created abstractions don't execute their loadbangs! It's possible to trigger the loadbang manually with a message to the subpatch, the objects are created in. For singleton.pd this subpatch's receiver is is pd-$0-container. Attached is a version of singleton which automatically sends a loadbang message to it. After I get over my jetlag, I'll consider making this the default in sssad's version of singleton.pd as well. Also it may be useful to send the value of $0 to an outlet, maybe the first one, but that may break patches which rely on only a 0 or a 1 coming out there, so I guess I'll have to introduce a second outlet.
