Possible Solutions

(0.1 0.2 0.3 0.4 0.5).1 {ch "G"} |

\track "Guitar" "gtr."
\staff{tabs} \tuning e4 b3 g3 d3 a2 e2
:4 3.6 0.5 2.5 0.4 2.4 |

expected result
the tuning show in above staff or track for each of it, open g tuning on the top and standard tuning on bottom staff

Sounds like a good feature. Guitar Pro shows tunings in case of multi-track display just side by side. alphaTab currently just takes the first one.

Added #463 into v1.2 but maybe I will also shift it to the backlog.

please be awared about chord definition too, because it will have different intepretaion
e.g.

\track "Keith Gtr"
\staff{tabs} \tuning d4 b3 g3 d3 g2 \chord "G" 0 0 0 0 0
(0.1 0.2 0.3 0.4 0.5).1 {ch "G"} |

\track "Ronnie Gtr"
\staff{tabs} \tuning e4 b3 g3 d3 a2 e2 \chord "G" 3 0 0 0 2 3
(3.1 0.2 0.3 0.4 2.5 3.6).1 {ch "G"} |

expected result
the chord defined show below tuning definition for each of it
if not defined around the tunning, the open strings sound of standard tuning will produce Chord Em11 not G Mayor Chord (expected result)

Rendering of the tuning was "beautified" a bit and we render now tunings of all tracks displayed. The track name is shown above the tuning in case multiple tunings are displayed:

Chords of all tracks were already displayed, but there was an issue with the unique chord ids in alphaTex.
