A MIDI track is created much like any other track (see Adding Tracks, Busses and VCAs). However, there are a few things that are unique to creating MIDI tracks.

When adding a MIDI track using the Add Track/Bus/VCA dialog, the MIDI Tracks item should be highlighted in the Template/Type list on the left. This will enable the Instrument combobox while disabling the Configuration and Record Mode comboboxes.

The Instrument combobox allows the selection of a plugin for the track to be created that will generate audio in response to MIDI data; if the track is intended to drive an external device then -none- should be selected instead.
