Be aware that if you're creating new abstractions on the canvas this way, pd (and/or) tcl/tk produces a noticeable spike in cpu usage, depending on the complexity (and visiblity - gop?) of the abstraction. I was about to check if lowering the priority of tcl/tk (that's wish8x.exe on win) could alleviate this
I didn't notice anything. But (for now) I'm just doing the simplest:
delete one object, create it with a new parameter and connect it to a
inlet / outlet. I'll look around anyway.
