RPG Maker VX Ace

Create the impression of layering ambiences by cueing variant tracks on the fly!


My dynamic music script allows the developer to switch between different variations of a track on-the-fly using variable changes and a simple, customizable naming system. When the player triggers a change to the specified variable (e.g., losing enough health on obstacles, encountering a puzzle, or entering a dangerous area) a new variant of the track is queued without restarting, subtly using music to indicate where and what situation is happening in an area. It can be useful for many types of games, such as Zelda-style games with action battle systems or adventure games with puzzles and enemies you must avoid.


  • Use variations of a track (e.g. “Forest”, “Forest1″, “Forest2″; or “Forest”, “ForestPuzzle”, “ForestCombat”) and have them cue automatically with just a variable change.
  • Almost seamless; there is a small crossfade between tracks done by the engine (if I could find a way to disable it I’ll add the feature in the future but it’s plenty useful as-is)
  • Customize the naming scheme (default is numeric), the number of variations the scripts supports (default is 4), and the variable used to switch between track variations (default is Variable 1).
  • Only works with OGG and PCM (WAV) files, as Mp3s and midis do not give the data required for the transition to work properly.

Terms of Use and Notes:

The script is free for commercial or non-commercial use, just give me credit either in the game or in a readme, or on the game page. If alterations are made to this script, I still require credit (or if you have ideas for extensions, feel free to let me know via my site or any other way you can reach me).

Note that this script is best with custom music, as dynamic music is actually quite rare in games and almost unheard of in RPG Maker games. It’s meant to improve ambience by having certain elements of the arrangement play only under certain circumstances, within the arrangement (like Soul Reaver‘s music engine, which inspired the script).
