Editing Names
To edit a Port name, click in the left (Custom Name) column to select the name. Then click again to invoke the edit control (or press F2). Type in the new name; the original name is always displayed in the right column. The Port icon color represents whether this is an input or output port. Input ports are colored Green; outputs are Light Blue. To remove a custom name, edit it and delete the text. It will be replaced by the original hardware port name.

After you have edited the names to your liking, press OK to save your changes; choosing Cancel will discard changes. The Custom Port names are saved globally. All running instances of MIDI-OX share the same custom Port names.
