Yes, but the "reference" device did not use the "plug" plugin, which was in the 
"default" device, which did not have the card parameter.

Try something like this:

pcm.reference {
        @args [ CARD ]
        @args.CARD {
                type string
                default 0
        }
        type plug
        slave.pcm {
                type softvol
                slave.pcm {
                        type hw
                        card $CARD
                        subdevice 0
                }
                control {
                        name "Reference"
                        card $CARD
                }
        }
}
