An 'interactive music engine', audio tool Psai has launched on the Unity asset store, providing developers with a way to create interactive music scores that adapt automatically to gameplay.
Included with the engine are eight free themes, composed by music specialists Dynamedion. It also comes with a music editor that can be used to compose the interactive soundtracks.
Psai is being used in a few upcoming indie titles, such as Mount & Blade 2: Bannerlord, The Devil's Men and Black Mirror III, among others.
The engine is completely written in C#, so that it will work on all of Unity's target platforms, both with the free and professional version of Unity.
