Harmony AI launches Composer Pro: generative music suite for game studios and raises $18M

Gaming · 4 min read

Composer Pro allows composers to define emotional states and rulesets so the engine generates adaptive music that transitions seamlessly during gameplay. The suite exports stems and interactive assets compatible with middleware like FMOD and Wwise, and includes tools for tempo locking and instrumentation constraints.

Harmony AI’s $18 million Series A, led by Soundline Ventures, will fund integrations, an expanded sample library, and partnerships with middleware vendors. The company also intends to develop a collaboration hub where composers and sound designers can version-control interactive music assets.

Early adopters in indie and mid-sized studios praised Composer Pro’s ability to quickly iterate on branching themes without hand-authoring dozens of variations. Harmony AI emphasizes composer control: generated material is a starting point, not a finalized score.
