Howdy, for main inlets (left inlet), you can add whatever kind of method to whatever kind of type, being it a signal, a symbol, a list... but not sure if you can do this with non-main inlets (the documentation pd-externals how to put up my IOhannes seems to confirm this).

anyway, i kinda needed a right inlet to accept a signal and float (but this float is not being converted to a signal, it'll set up a specific method setting)

cheers
