Vibrato does not play for more than one bar

[MrDrone-ru]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The vibrato stops at the end of the bar, then one note from the vibrato range plays, not necessarily the base one.

Expected Behavior

Vibrato for the entire duration of the note.

Steps To Reproduce

Play a vibrating note, which consists of 2 or more notes linked through a bar.
4-5 bars in my example

Anything else?

Also I wanted to change the vibrato option via code:

const settings = {
                    file: ".....",
                    player: {
                        enablePlayer: true,
                        soundFont:'https://cdn.jsdelivr.net/npm/@coderline/alphatab@latest/dist/soundfont/sonivox.sf2',
                        scrollElement: wrapper.querySelector('.at-viewport'),
                        vibrato: {
                            noteSlightLength = 350
                        }
                    }
}

But it caused an error "Invalid shorthand property initializer"
However, this

api.settings.player.vibrato.noteSlightLength = 350;
api.updateSettings();

works fine.

In your settings object you have a syntax error. You are using an = sign to define values which is not valid JavaScript. You need to use a : there.

Regarding the bug: Actually in the GP5 file, the tied note on bar 5 has no vibrato applied, so the audio playback is correct. I double checked the binary file during reading, and there are no vibrato effects on this note. So the file reading is correct.

It seems a bit funny that we are having the same bug like Guitar Pro in alphaTab because they also flag the tied note with a Vibrato on import:

While from a file format perspective the bugfix would be correct to not show a vibrato on the tied note, I think it would be better to keep the current display and ensure the audio is generated also with a vibrato.

What holds me a bit back to just make the change is that it could be that someone has a vibrato only on the first note, but stop at the second note.

Thanks for reply.
I just thought that it would be possible to set up the behavior of AT like in Guitar Pro 5, and there the tied note plays vibrato without a sign. It probably plays the tied notes as one, and it turns out to be a bug.
Interestingly, if this file is imported into GP8, there is automatically vibrato on both notes.
