    Composes, arranges, performs and mixes original instrumental music as editable notes. The agent writes every note into a project file; scripts check the score, play it on sampled instruments (pianos, guitars, basses, drums, orchestra, saxophones, erhu, steel drum, mallets, organ) or built-in synthesizers, Surge XT presets and drum machines with player-like timing, dynamics, swing and legato, mix it with buses, sidechain, delays and reverbs, and master it to MIDI, stems, an MP3 and seamless game loops. No audio-generation model: every note can be changed and re-rendered. Use it whenever the user wants an original instrumental track, game, film, video or visual novel music, an RPG scene, horror or anime-opening-style cue, orchestral, baroque, piano, jazz, blues, bossa nova or organ music, pop ballads, rock, metal, EDM, techno, synthwave, chiptune, lo-fi, boom bap or trap beats, an arrangement, a revision of one phrase, editable MIDI, stems or a mix, even if they only ask for 'a song' or 'some music'.
