Let the whole orchestra evolve.
Grow melodies, sculpt their voices, teach the ensemble your taste.
Four engines. One living score. A sound only this garden could make.
Planting the first population…
The living population
A living arrangement
Click a lane to add a quantized note; click an existing note to remove it. Edits create a new, saved variation. Drums use kick / snare / closed hat / rim by lane height. Audio and JSON retain fractional tuning; MIDI rounds to semitones.
Choose a voice. Change the ecosystem.
The archived originals stay unchanged.
Harmonic sculpture & arrangement curves
Eight additive partials. Fundamental is anchored; the other seven evolve and learn a spectral target. These partials sound through “Living harmonics”.
Falling Empire’s three-point arc becomes bar-level density, breath, space and width automation. These are genes, not the protected master gain.
Keep what matters.
Current-generation champions, hall elites, rotating ancestors, favorites and diversity representatives are protected from learning and mutation when carried forward.
Learn. Explore. Listen.
The search controller learns which mutation families improve craft. The diversity atlas protects alternative solutions; your comparisons train a small preference model.
What the learner actually optimizes
Neural gradients optimize an explicit motif-and-chord teaching loss, not perceived beauty. Spectral descent fits eight harmonic amplitudes. Coordinate search checks generated notes; symbolic craft and novelty drive population selection. No gradients pass through quantized scores, imported synthesizers, or your speakers. Audio is rendered only for listening or export.
