Chord Symbols style
Adjust chord symbol following simple replacements. Needs MuseScore 3.3 or higher to function.
Since the api doesn't allow much for selections, to run these plugins you have to select manually an example object. See usage for more details.
First open the file in any text editor (such as Musescore's plugin manager)
Add or remove replacement rules.
For example to replace all Maj7 with a triangle followed by a 7 (t7) add the following rule:
txt = txt.replace("Maj7", "t7");
or more simply:
txt = txt.replace("Maj", "t");
Select a Chord Symbol and run the plugin.
