This method works pretty good nowadays indeed, sorry to not put
explanation comments, but I can give some clues...
We create [dac~ n] (n is channel number) in a subpatch protected with $0
variable in subpatch name.
Instance specific dynamic patching is explained here but this is a bit old:
Now we can put $0 at the middle of a name, then [makefilename] method
I don't think we would go on mem alloc issues by doing simple things
like this, it might happen on huge dynamic creation but I never
maybe someone that knows better pd core would give more accurate answers.
Also, I've made it fast and figured out that [t b b]-[$1] is useless,
you can directly connect [loadbang] to [pack $0 $1].
Look at internal messages to know more about dynamic patching:
