not yet...but if you post the patch, or the part with th 200 or more  

i would test the difference.

I am surprised where this discussion is going...many useful tips so far.

I personally dont like that $0 $1 confusion somehow, but thats just  
because i dont remeber what i did when i open
the patch many months later or so..

Wires are somehow more "haptic" and its a part of pd that i like,  
sort of the typical pd-character, but
as in the 24 24 matrix thing - when you have to do more than 100  
connections in one patch, then its kind of silly, this weaving
so dynamic object creation or just "automated" connecting seems to be  
a good way..

To come to a little bit more practical example..

I am facing the problem - again with the mapping library - and this  
is, where it does not work with abstractions - i would like to have one
abstraction with a mapping object inside, but not always the same...

i post the example, later - where i am now experimenting with this  

basically its like that..

lets say you have an abstraction:


inside of that there is the core-math object like

exponential_curve or exponential_sigmoid

so it would be cool to just send the argument "expoential_curve" to  
the abstraction so this object is created..

well...not very clear i guess..

but i will post it later

What about the

route audio~ float  - object ....

did nobody ever have the same problem ??

good night luigi
