PlusMusic Documentation
The PlusMusic Adaptive Music Platform (AMP) is a complete game music solution and a true platform for developers. AMP is designed for ease-of-use and virtually instant implementation into Unity and Unreal game engines. The AMP middleware enables you to connect your game project with the AMP Music Library of handpicked, artist-created tracks for quick and seamless adaptive music playback in your game.
If you don't already have a PlusMusic account, go to app.plusmusic.ai and click sign up. Access to AMP middleware including the web-based Dev Portal and the Unity/Unreal Plugins is free, and developers with titles in development can get unlimited access to watermarked tracks in the Music Library. For projects set for public release, we offer tiered pricing for music licensing that scales as your player community grows.
Music tracks from the Library are automatically analyzed and mapped into sections called Adaptive Music Sequences (Sequences) that can be triggered in-game. We use proprietary Machine Listening processing to identify Sequences in the music according to criteria such as intensity, mood, and style. The full set of Sequences that can be used in your game project are available in the Dev Portal at app.plusmusic.ai.
In your game engine project, you specify Sequence triggering using our predefined prefabs, scripts, or blueprints. You can select transitions between Sequences, add stingers, adjust volume and intensity. Through this workflow, you define an in-game adaptive playback structure for the music that is independent from the specific track that is playing. Once the in-game adaptive playback structure is set, any track from the AMP Music Library will conform and playback according to those instructions.
In addition to Sequences, each track is separated into 4 layers or "stems" such as bass, drums, vocals, and top mix. The volume for each layer can be controlled independently. You can use the tracks in your project as a set game score, switch tracks from a predefined playlist, play them at random or even allow the player to choose which tracks to play at runtime.
We currently offer eight (8) Sequence types for each track:
high_backing
low_backing
backing_track
victory
failure
highlight
lowlight
full_song
High intensity exploration
Low intensity exploration
Mid intensity exploration
