Expert Tips

What the pros know

Pro Tip

Rendering a whole soundtrack? Upload the batch in one go. Every track comes back normalized to the same level, which saves you gain-matching them by hand in the engine's mixer.

Common Mistake

Setting a loop point in the engine without listening to the ending first. The trailing silence is trimmed, but a long reverb tail that's part of the music still needs a crossfade or a chosen loop point.

Best For

Turning MIDI game music, your own or the retro classics, into background-music assets for Godot, Unity, and other engines that import OGG.

Not Recommended

OGG for an Apple-first audience. iPhones and Apple Music handle it poorly or not at all; render to M4A for that crowd.

FAQ

Frequently Asked Questions

Not out of the box. Both engines expect audio assets and would need a synthesizer plugin to perform MIDI at runtime. Rendering to OGG ahead of time is the standard approach.

The trailing silence a synthesizer leaves after the last note is trimmed automatically, which removes the usual cause of a gap at the loop point. Still listen to the ending; a reverb tail that's part of the music may want a crossfade.

Vorbis is open and royalty-free, so the format itself costs nothing to ship. The music's own copyright is separate; that depends on the MIDI you're converting.

Old games played their music through the sound hardware of the era, often FM synthesis chips. Our render uses FluidSynth with the FluidR3 General MIDI soundfont, which is sample-based, so the same notes come out with a different character.

OGG is the container, Vorbis is the audio codec inside it. Files here are Vorbis audio in an OGG container, which is what game engines mean when they say they support OGG.

Game Engines Take Audio Files, Not Note Data

Godot and Unity import OGG directly; neither plays a MIDI without a synthesizer plugin doing the work at runtime. The practical route for a town theme or battle loop you have as .mid is to render it once, up front, and ship audio. This page performs the score through FluidSynth with the FluidR3 General MIDI soundfont and encodes the result as OGG Vorbis.

A lot of the MIDIs people convert this way are old game music, which fits. MIDI carried game soundtracks through the 90s, and an OGG render puts those tunes back into a modern engine.

The Silent Tail That Ruins a Loop

A raw synthesizer render doesn't stop when the music does; padding and reverb leave dead air at the end. Across our test files that tail ran from 2.2 to 8.6 seconds per file. We trim it automatically, and for background music that loops, that's the difference between a clean cycle and a track that goes quiet before restarting.

Loudness is normalized by default as well, so a batch of rendered tracks sits at a consistent level when it reaches your mixer.

How to Get From .mid to .ogg

Upload one or more MIDI files.
Set OGG as the target.
Download each OGG as its render completes.

Files render on our servers, not in the browser: you upload the MIDI and download the finished OGG.

Why OGG for This Job

Vorbis is open and royalty-free, so engines and Linux distributions ship support without licensing anything, and quality per megabyte holds up well against MP3. Godot's own documentation recommends it for music. If the destination is a phone's music library rather than an engine, MIDI to MP3 travels better.
