Question 1

How do I loop a MIDI file in html-midi-player?

Accepted Answer

Set the 'loop' attribute to true on the <midi-player> element, either in HTML or via JavaScript with player.loop = true. This makes the player automatically restart after finishing, as shown in the API basics section.

Question 2

Can html-midi-player play multiple MIDI files at the same time?

Accepted Answer

No, it has a limitation where only one player can be active simultaneously. Starting a new player stops any currently playing one, which is explicitly mentioned in the limitations and affects multi-track applications.

Question 3

How to change the visualizer to staff notation?

Accepted Answer

Question 4

html-midi-player vs MIDI.js: which is better for web projects?

Accepted Answer

html-midi-player is better for simple, declarative embedding with built-in visualization, while MIDI.js offers more low-level control over MIDI synthesis. Choose html-midi-player for ease of use and visualizers, MIDI.js for custom audio pipelines and broader browser support.

Question 5

How to load a local MIDI file without uploading it online?

Accepted Answer

You need to serve the file via a local HTTP server, as browsers block direct local file requests. The FAQ suggests starting a simple server and using a relative or absolute URL to the hosted file for testing.

Question 6

Does html-midi-player support real-time MIDI keyboard input?

Accepted Answer

No, it's designed for playback from pre-loaded MIDI files or NoteSequence objects, not real-time input. Adding live performance features would require integrating additional libraries beyond its scope.
