Charting Songs with Editor on Fire (EOF)

Editor on Fire (EOF) is the community chart editor most Frets on Fire and Clone Hero charters use. It is free, and it produces the notes.mid file that Frets on Fire reads. Charting well takes patience: a good chart is timed to the music, not just notes dropped on a grid.

Set up a chart

Create a song folder with your audio as an Ogg Vorbis file, then open it in EOF and set the song’s tempo map by tapping along to the beat.
Place the beat markers first, then chart one difficulty at a time — start with Easy or Medium and build up.
Use the guitar audio track for the notes you chart; the backing mix belongs in song.ogg, not in the playable track.

Test before you share

Play the chart in Frets on Fire or FoFiX at full speed and at half speed, and fix any notes that feel early or late.
Check every difficulty you claim to support — an untested Expert chart with impossible chords helps nobody.
Fill in song.ini with the correct title and artist, and credit the original song and any chart source honestly.

How to Add Custom Songs to Frets on Fire

Frets on Fire’s real library is its custom songs. Every song is a folder, and the game only sees it when the folder layout is exactly right. This guide covers vanilla Frets on Fire and FoFiX; the layout is the same, only the songs folder location changes.

The song folder layout

Windows (portable or installer): [game folder]\data\songs\[song name]\.
Each song folder must contain song.ini (title, artist and metadata), notes.mid (the chart) and guitar.ogg (the playable guitar audio).
song.ogg (backing audio) and artwork such as label.png are optional.

Add a song, step by step

Extract the song archive and check that notes.mid and guitar.ogg sit directly inside the song folder — not inside a second folder with the same name.
Rename the folder to something simple, with no special characters, and keep file names lowercase on Linux.
Restart the game (or rescan, in FoFiX) and look for the song in the song list.

If the song does not appear

Work through songs not showing: the double-folder problem causes most cases, followed by a wrong file name (notes.mid, not notes.MIDI) and a missing guitar.ogg. This wiki does not host or link commercial song packs — only use charts you made, charts shared freely by their creators, or audio you have the right to use.
