调研方向

Start from the tuning model that holds each string's alteration, then follow it through the three inputs the issue names: the Guitar Pro importer, the alphaTex parser (which currently has no syntax for alterations), and the MusicXML importer, where the tuning-alter element's sign says sharps or flats. Finally the renderer that prints tuning names must stop forcing sharps and use the per-string alteration. Done means a GP file, an alphaTex string and a MusicXML file each display the author's intended accidentals. Note an open pull request (#2838) already targets this.

描述

https://github.com/CoderLine/alphaTab/discussions/2785

Problem

Currently alphaTab forces the use of sharps on the string tuning display. It doesn't allow changing the tuning to prefer the display of flats. Guitar Pro also allows specifying the tuning alteration.

Desired behavior

alphaTab should allow customizing the exact display of tunings.

  • The guitar pro input should be respected
  • alphaTex needs to allow specifying the alteration too. Likely we should adopt the alteration as explicitly written by the author. That means the alteration should be per-string, not globally.
  • On MusicXML the https://www.w3.org/2021/06/musicxml40/musicxml-reference/elements/tuning-alter/ might give an indication whether we have sharps or flats. Negative values are flats and positive ones sharps.
