Adaptive game music

Switch between exploration and combat on a musical boundary and add or remove layers while the pad keeps sounding. Playback uses a separate 16% host monitor gain; begin with a low device volume.

Sections

Section

Boundary Swing for the built-in demo's arp and lead (Reset demo applies it) Crossfade / layer gain fade (seconds) Let removed layers finish their current gates (otherwise release after the fade; positive fades still mute them)

Layers (effective at the current beat)

Layer gain target Gain 0..1 (release slider to commit on the selected boundary)

Portable arrangement project Load arrangement JSON (at most 8 MiB)

Save includes named voices, synthesis settings, tempo/meter, sections and edited layer/gain targets. Loading replaces and stops the prior owned arrangement; Start is always explicit. Names and controls are rebuilt from the file, including projects with different sections/layers. Live beat position, pending changes and fades, oscillator/envelope/filter state are not saved.

No audio created.

Positive fades crossfade removed and incoming layers; shared layers stay continuous. Try lowering the shared pad gain while switching sections. Layer gain multiplies note expression without changing global engine gain. A change commits no earlier than the notes already admitted to the audio clock. Pause releases owned notes; Resume restarts musically from that beat, not an exact DSP-state restore. Tempo ramps are linear in BPM across beats.
