MIDI Track Licenses & Sources
Review the license and original source for every curated MIDI track, plus the bundled SoundFonts used by the browser player, before you download, publish or redistribute audio.

01 — Read first
Attribution is part of the track
Miditor's public player reads a curated third-party MIDI catalog through
a same-origin Miditor API route. Each record keeps a
license and source_url field alongside the
title, composer and MIDI URL so the rights record is visible in one
place.
If the live catalog is unavailable, a small set of Miditor-owned demo arrangements marked CC0 1.0 keeps the player usable offline. The A320U SoundFont files are separate GPL v2 assets; using the player does not transfer ownership of those files. When a field is blank, the rights are not verified by this page; contact the source or do not reuse the file.
02 — Before reuse
Check the permission you need
Keep the source visible
If you publish or share a permitted track, preserve the required credit and link back to the source URL shown in the directory.
Ask when metadata is missing
“License not provided” and “Source URL not provided” mean exactly that: this page cannot establish permission for you. SoundFont notices are listed separately from MIDI track records.
03 — Curated catalog
Track attribution directory
This directory reads the same curated queues used by the MIDI player and keeps one row per track. Search by title, composer, instrument, style or license to find the attribution you need.
04 — Browser audio
Bundled SoundFont notices
Miditor bundles the A320U General MIDI bank and its compact drum bank so playback and conversion can work without a runtime audio provider. Both assets are released under GNU GPL v2 by their original author.
Read the A320U license notice and the linked GPL v2 text before redistributing the SoundFont files themselves.
Quick answers
Frequently asked questions
Where does a MIDI track's license come from?
The player reads a curated third-party MIDI catalog and preserves each record's license and source URL. A small Miditor-owned demo catalog is used only as an offline fallback. The page also records the separate license and source information for bundled SoundFonts used for browser playback.
What if a track has no license or source URL?
Treat missing metadata as unverified. Do not redistribute, publish or use that track commercially until you have confirmed the rights with the original source.
Can I redistribute MIDI files from the player?
Only when the individual track's license permits it and the required attribution is preserved. The catalog license is not a blanket permission for every track. SoundFont files are separate third-party assets and remain subject to their own license and notice requirements.
