Changeable Argument in gen~

Hello,

I'm making a bpatcher abstraction which I will use multiple instances of it.

The abstraction has a buffer~ object which has its own independence from the other instances as its name contains a changeable argument in its name. This changeable argument is set to the first argument of the bpatcher.

Now, I have a buffer operator in gen~ in the bpatcher abstraction and I want it to recognize the buffer~ outside gen~.

The challenge is that gen~ can have only one argument (the name of the referred gen~ file), and "args" is not valid unlike for poly~ or pfft.

I attached a simplified example to this message -- obviously it's not working well as gen~ has no argument.

Does anyone have a good idea?

Many thanks in advance!
