• Show Duplicate Emulated Ports
When this option is selected and you are using a MIDI interface that supports time-stamping, the MIDI Studio setup window shows both the DirectMusic time-stamped output ports, and non-stamped duplicate emulated output ports.

Some MIDI Interfaces will not properly load or unload their drivers unless you quit and re-launch Pro Tools | First. Refer to the documentation that came with your MIDI interface for more information.
