some time ago, i built an fx-bank with some fx and a routing subpatch in it. as i remember, this worked without issues. but when i now open the fx_bank.pd in the attached zip file, and then open the routing subpatch at the left of the gui, i get a tcl error message (invalid command name....) and the gui is completely messed up.
what is the reason for that? has that got something to do with the [popup] externals? can someone help?
