Adaptive Music System Pro is a complete solution for dynamic,

interactive game music in Unity. It gives you full control over

how music reacts to gameplay — from smooth beat-synced

transitions and vertical layer mixing to parameter-driven

intensity changes and spatial music zones.

Whether you're building an open-world RPG, a stealth game, or a

narrative adventure, this system lets you create a

professional adaptive soundtrack without writing complex audio

code.

Vertical Layering

Stack up to 9 layer types (Percussion, Bass, Harmonic, Melodic,

Ambient, SFX, Vocal, HighEnd, Custom) per track. Fade layers

in and out based on gameplay parameters with smooth volume

interpolation. Set conditions per layer — the system activates

and mixes layers automatically.

Horizontal Sections

Define intro, verse, chorus, bridge, outro and custom sections

within a track. Transition between sections using 8 transition

types: Immediate, Crossfade, OnNextBeat, OnNextBar,

OnSectionEnd, OnExitPoint, WithStinger, and Custom. Queue

sections or jump directly.

Beat Clock

Sample-accurate timing powered by AudioSettings.dspTime. Tracks

BPM, time signature, current beat, bar, and sub-beat position.

Schedule events on the next beat, bar, downbeat, or at a

specific DSP time. Built-in drift correction keeps everything

tight.

Parameter System

Drive the music from gameplay with float, bool, integer, enum,

and string parameters. Map parameters to layer volumes, filter

cutoffs, section transitions, and stinger triggers through the

automation system. Group parameters in the dashboard for

organized control.

Stinger System

Trigger one-shot musical accents (sword clashes, level-ups,

discoveries) with beat-quantized timing. 10 built-in

categories. Priority system prevents overlap. Automatic music

ducking with attack/hold/release envelope.

Mood System

Define mood profiles as ScriptableObjects with parameter

presets. Switch between Combat, Exploration, Stealth, Tension,

and 10 other built-in moods. Smooth blending between mood

states with configurable transition speed.

Music Zones

Place MusicZone components in your scene with collider

triggers. The system handles priority-based zone selection,

crossfading between zones, parameter overrides, and

layer-specific blending. 4 blend modes: Cut, Crossfade,

FadeThrough, LayerBlend.

Ducking System

Multi-source ducking with 6 categories (Dialogue, Stinger, SFX,

Cutscene, UI, Custom). Priority-based management with

attack/hold/release curves. Integrates with StingerSystem and

is available through MusicManager API.

5 Editor Windows

Music Composer — track editing, layer stack, section timeline

Transition Matrix Editor — visual grid of all

section-to-section transitions

Stinger Browser — browse, preview, and organize stingers by

category

Parameter Dashboard — real-time sliders, parameter groups,

save/load presets via JSON

Music Debug Window — live playback state, beat visualization,

layer status

Runtime Debug Overlay

Toggle with F3 in Play Mode. Displays track info, beat/bar

position, layer volumes, parameter values, transition progress,

and a real-time audio spectrum visualizer. Configurable

anchor, opacity, and sections.

Integrations

Timeline — custom tracks and clips for cutscene music control

Yarn Spinner — dialogue commands: music_play, music_layer,

music_parameter, music_stinger, music_duck

Ink (Inkle) — tag-based control: #MUSIC:, #LAYER:, #MOOD:,

#STINGER:, #PARAMETER:, #SECTION:

Performance

Object pooling for AudioSources (8 layer + 4 stinger default,

auto-expand to 32+16). Zero GC allocations at runtime.

Configurable concurrent layer limits. Mobile optimizer

component. DSP-accurate scheduling with drift correction.
