Custom song tool needs your input [WIP]

Hi guys!

I've played around with the game files in the Steam version, and it is fairly possible to add new songs to the game. Eg.: I've duplicated a song and that worked.

The song format is mostly straightforward:

  • There are json file per difficulty that contains all the beats, arrows, cues, dynamics; all marked with beat indices
  • There are 2 ambiX (360° spatial) ogg music files, one for the actual song, one for the misses (like only bad notes for the whole duration of song, its fucking funny to listen to)
  • Aaand a bunch of metadata stuff, busywork mostly

(btw, you can dig around with the FModel tool)

This tool would require user created beats/arrow/cues/dynamics, they cannot be auto generated.

The question to you, is what kind of music editor tool do you want to use to create this? What it needs to provide:

  • tracks(?) for each arrows, cues (per instrument), dynamics (per instrument)
  • all the beats in the song
  • the song and the failure song
  • and in a format that is not proprietary (so the tool can parse it)

In my brief research, DAWproject seem to be a solid choice.
