Encore Chart Format

To work in Encore, a chart requires the following:

  • Properly formatted info.json
  • At least 1 backing.ogg
  • At least 1 valid instrument track in <name>.mid

Details about these files and the format will be noted below.

info.json

A fully fleshed out info.json file will look similar to the following:

{   
	"title": "Through the Fire and Flames",    
	"artist": "DragonForce",    
	"preview_start_time": 41727,    
	"release_year": "2006",    
	"source": "rb3dlc",    
	"album": "Inhuman Rampage",    
	"loading_phrase": "Woah it's an encore in here!",    
	"genres": [    
		"Power Metal"    
	],    
	"charters": [
		"Harmonix",
		"TheGuitarHeroNerd",
		"Gwarb"
	],
	"length": 449,
	"icon_drums": "Drum",
	"icon_bass": "Bass",
	"icon_guitar": "Guitar",
	"icon_vocals": "Vocals",
	"diff": {
		"drums": -1,
		"bass": 5,
		"guitar": 6,
		"vocals": 4,
		"plastic_drums": -1,
		"plastic_bass": 5,
		"plastic_guitar": 6,
		"pitched_vocals": 4
	},
	"midi": "notes.mid",
	"art": "cover.png",
	"stems": {
		"drums": [
			"drums_1.ogg",
			"drums_2.ogg",
			"drums_3.ogg"
		],
		"bass": "bass.ogg",
		"lead": "lead.ogg",
		"vocals": "vocals.ogg",
		"backing": [
			"backing.ogg",
			"keys.ogg"
		]
	}
}

The minimum fields required are

  • "title"
  • "artist"
  • "diff" and child fields, like "drums", "bass", "guitar", and/or "vocals"
  • "stems" and at least its child field, "backing"
  • "midi"
  • "sid" or "icon_drums"
  • "sib" or "icon_bass"
  • "sig" or "icon_guitar"
  • "siv" or "icon_vocals"

Because the info.json file uses JSON, it is very much noted that you should always follow JSON syntax. JSON and its various syntactial quirks will not be covered here, but the most notable issue is that capitalization is parsed, and any incorrect capitalization can render a field useless.

Unlike other song formats, the midi file does not have to be named notes.mid, as long as its name is properly noted under the "midi" field.

notes.mid

This is formatted extremely closely to a regular CH/RB chart that utilizes a notes.mid, although any plastic/5-fret/Pro/Classic chart should be in a track named PLASTIC_<inst>. All PART_<inst> tracks should be formatted for Encore pad gameplay.

Note, <inst> is a placeholder for the instrument being charted. All acceptable instrument track names at this time are PART_DRUMS, PART_BASS, PART_GUITAR,PART_VOCALS, PLASTIC_DRUMS, PLASTIC_BASS, and PLASTIC_GUITAR.

Refer to the chart below for the different difficulties and pitch information.

Solos

Solos are marked per instrument at pitch 101 (F6), between Expert's lift and tap pitches.

EVENTS and BEAT

Every notes.mid needs an EVENTS track and a BEAT track.

Beat

BEAT is a mapping of each beat line to be displayed in Encore. On pitch 12 is any major beats, like the first beat of the measure. Even though you can technically use any other pitch, it is highly suggested to use pitch 13 for any other minor beat. Typically, the templates distributed will already do this for you.

Events

EVENTS has three required text events.

  • A [music_start] event tells the game where the first beatline should appear.
  • A [music_end] event tells the game where to stop displaying beatlines.
  • An [end] event should be placed at the very end of the chart MIDI, or where the game should cut to the Results screen.

Audio

As Encore uses BASS and BASSOPUS, you can use WAV/AIFF/MP3/MP2/MP1/OGG/OPUS files for music. OGG and OPUS are highly recommended.

Album art

Album art must be .png or .jpg, with a size of 512x512.
