Hi Philipp. (2nd time for you, 1st time for the list)

your rigth, here it is from Miller :
"connect object-number outlet-number object-number inlet-number".
The four numbers count from 0 up; objects are bnumbered in the order they're
So "connect 1 3 0 0" would be "connect the fourth outlet of the second
object to the first inlet of the first object".

I don't think so, but I'm not a specialist of it....

Here what i've found on the list that looks realeted :
 |Does anyone know of a way to dynamically destroy an object using the
 |"send pd-xxx" approach? Also, is there anyway to disconnect objects

did you find/make anything?
i ve only managed to selectall,menu_cut and start over from scratch. ;)

the problem with both destroying and disconnecting is getting the
reference to the object.
 you could either emulate a mouseclick,
or work out how to access the stuff via canvas/glist directly,

 |I agree...  there's no way (as yet, anyway) to get a pointer to the last
 |created object in a patch (for instance) so taht you could store it and use
 |it later to delete the object.  Doing this well would be somewhat


 |and would make the "pointer", etc., objects run slower (stale pointer


 |would be harder.)
 |An easier hack would be to give canvases a way to delete objects by


 |index... would that help?

that would totally help, since, given you re building patches from within pd,
you have to keep track of the object-positions anyway, in order to make

Hope this help you.
