Is it possible to change the number of inlet or outlet from inside callback functions, eg receiving the message "inlet 5" will cause inlets to be added/deleted to get those 5 inlets.

We know from the buddy example how to change that number from passing arguments typed in the object box, but found no way for a more dynamic behaviour.

You could always prefix you input/output messages with an int

specifying what "virutal inlet.outlet" messages belong to.

Thnaks for answering. My purpose was actually to change the inlet/outlet count after the object has been created. I was looking for the same behaviour you have when using the script message "replace" with arguments for changing inlet/outlet count. But probably, the script deletes the old object and creates a new one for replacement.

In fact, we found some workaround, but were interested in your answer for a better understanding of the setup/and object_new functions.
