transpositionPitches doesn't work on the fly (dynamically)

[kinesphere]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

In JS, after the initial render, if I run:

api.settings.notation.transpositionPitches = [7];
api.updateSettings();
api.render();

Nothing changes. All other things I tested work (e.g., api.settings.display.scale = 1.2;), but transpositionPitches and displayTranspositionPitches won't work, although they work fine in the initial render.

Expected Behavior

The notation should display the new pitch (different notes, in the case 7 semitones above from what is shown in the initial render).

Steps To Reproduce

1. Initialise an alphaTab JS in HTML loading a GP file.
2. Test in Firefox web developer tools via console, or by creating a function for transpositionPitches, updateSettings and Render.

Anything else?

The fix for me was to modify the library, adding inside the render function:
ModelUtils.applyPitchOffsets(this.settings, this.score);

I don't know where is best to have this, but it fixed the issue for me.

👍 I also encountered this when trying to implement an on-the-fly transposition feature.
