[PD] Strange bug in my patch

I remember a bug in PD that if you create an instance of an abstraction 
(even by hand with ctrl+1) which contains dsp objects, its content 
doesn't start doing dsp processing until one more object is created 
(i.e. it is not added to the dsp chain when it should).

If more than one object (abstraction instances) are created in one 
message-tree (i.e. triggered by one "bang"), _maybe_ all of them will be 
mute until the creation of any new object in a separate message tree.

So a workaround in your case could be to programmatically create some 
"dummy" object after creating new "attack generators" and "pitch 
shifter". If the guess I have exposed in the second paragraph is 
correct, you will need at least a [delay 0] before the creation of the 
dummy object.

However I think you could implement the whole thing without dynamically 
creating objects, by acurately arranging sends, receives (with and 
without tilde), throw~s, catch~s, statically creating a big number of 
"allocatable" objects (capable of playing one table now, another one 
later etc according to messages they receive), managing polyphony (maybe 
with [poly]) and of course, switch~ing off every object that is not 

By the way I don't see anything inconvenient at all in what you asked :)
