* Read track.

*
* - *0x01*: drums track
* - *0x02*: 12 stringed guitar track
* - *0x04*: banjo track
* - *0x08*: *blank*
* - *0x10*: *blank*
* - *0x20*: *blank*
* - *0x40*: *blank*
* - *0x80*: *blank*
*
* Flags are followed by:
*
* - Name: :ref:`byte-size-string`. A 40 characters long string
* containing the track's name.
*
* - Number of strings: :ref:`int`. An integer equal to the number
* of strings of the track.
*
* - Tuning of the strings: List of 7 :ref:`Ints <int>`. The tuning
* of the strings is stored as a 7-integers table, the "Number of
* strings" first integers being really used. The strings are
* stored from the highest to the lowest.
*
* - Port: :ref:`int`. The number of the MIDI port used.
*
* - Channel. See :meth:`GP3File.readChannel`.
*
* - Number of frets: :ref:`int`. The number of frets of the
* instrument.
*
* - Height of the capo: :ref:`int`. The number of the fret on
* which a capo is set. If no capo is used, the value is 0.
*
* - Track's color. The track's displayed color in Guitar Pro.*/
