Observed Results

Same score rendered by AlphaTab:

I observe at least 3 problems:

• The quarter notes are displayed with a flag, like eighth notes
• The time signature is missing
• The rests are missing

Steps to Reproduce (for bugs)

Initialise AlphaTab with these options:

$('#alphaTab').alphaTab(
    staves: { id: 'tab', additionalSettings: { 'rhythm': true } }
);

(Like in the Guitar Tabs sample, which is not working in the online demo, by the way)

Good finding. I haven't used the tab-only display a lot so I missed various details. In the latest commits I added several improvements to the tab-only rendering:

• Quarter notes are rendered properly now
• Time signature is now rendered for tab-only display
• Rests are added
• Dotted notes are shown properly

I compared the alphaTab output with the Guitar Pro rendering and beside some minor alignment differences it should show the features correctly now.

Is there anything else you spotted already?

Great ! You definitely are a very efficient developer. I'll let you know if I observe other display errors.

Just in case you didn't notice it, the two first examples under the "Guitar Tabs" tab are missing in the online feature samples. It seems like the files/features/Rhythm.gp5 file is missing.
