ACE-Step v1.5 XL Base

A cinematic chamber-pop track set in a terraced citrus orchard after sundown: warm flugelhorn lead, pizzicato cello ostinato, marimba droplets, bowed vibraphone shimmer, brushed frame drum, and tight electronic sub pulses. Female alto vocal in Spanish with close-mic intimacy, call-and-response with a small male baritone harmony in the chorus. Structure: 8-bar atmospheric intro, verse with sparse bass and hand percussion, pre-chorus rising strings, expansive chorus, instrumental bridge featuring odd-meter marimba and muted brass, final chorus with layered harmonies, clean ending. Mood: tender, curious, quietly triumphant; high-fidelity studio mix, wide stereo, natural dynamics, clear lyrics.

Replace only the designated ten-second middle passage with a distinctive case-file stinger for an aquatic veterinary podcast. Transition naturally from the incoming muted electric piano by letting its final chord ring into a close-miked pattern of delicate stainless-steel instrument taps, then introduce a tense three-note bass clarinet figure, bowed vibraphone shimmer, and a brief filtered hydrophone texture resembling movement inside a treatment tank. The passage should feel precise, diagnostic, and quietly urgent, with a clearly different timbral identity from the surrounding bed. Preserve the source tempo, key, room character, and broadcast loudness. In the final two seconds, thin the percussion and resolve the clarinet figure so the untouched brushed drums and electric piano can return seamlessly. Instrumental only; polished professional podcast mix.

A 150-second cinematic electro-tango set in a volcanic rail depot at midnight: bandoneon lead, muted trumpet replies, deep upright bass, brushed snare, crisp palmas, low analog synth pulse, occasional steel-wheel percussion, and a smoky solo female Spanish vocal. Structure: tense 8-bar intro with distant train brakes and sub-bass rumble, sensual verse, explosive pre-chorus with claps, hook with soaring bandoneon and trumpet, instrumental break using rail-metal hits as rhythm, final chorus with layered harmonies, clean resolved ending. High-fidelity studio mix, wide stereo field, punchy but warm low end, dramatic dynamic swells, modern soundtrack polish, danceable yet mysterious.

Create a seamless natural continuation of the supplied podcast theme for an investigative series about forged manuscripts, stolen first editions, and provenance disputes in the antiquarian book trade. Preserve the source audio's tempo, key, acoustic space, dry production, four-note motif, and distinctive palette of harpsichord, felt piano, pizzicato cello, brushed drums, and restrained tape texture. Do not restart or abruptly change style at the edit point. Gradually develop the motif through a slightly tenser harmonic turn, add a subtle bass-clarinet counterline and crisp rim-click pulse, then reduce the arrangement into a concise, authoritative final cadence. End with a clean, convincing broadcast-ready sting rather than a fade. Sophisticated editorial tone: curious, meticulous, quietly suspenseful, never melodramatic or horror-like. Instrumental only, with enough midrange space for a host voiceover.

Compose a polished 60-second instrumental opening theme for “Spore Evidence,” an investigative podcast about forensic mycologists using fungal traces to help solve crimes. Distinctive electroacoustic noir with restrained broken-beat jazz: dry bass clarinet motif, muted vibraphone, pizzicato cello, brushed snare, soft sub-bass, prepared-piano ticks, and subtle granular textures resembling spores moving beneath a microscope. Intelligent, curious, methodical, and slightly uncanny, but never horror. Begin with a crisp three-note sonic identity and sparse microscopic detail; establish the main motif quickly. Around the middle, reduce to a steady, unobtrusive pulse with minimal harmony and ample frequency space for host narration. Gradually reintroduce vibraphone and bass clarinet, then finish with a concise, confident version of the three-note identity and a clean resolved ending suitable for an edit point. Premium public-radio production, intimate acoustic detail, controlled dynamics, memorable melodic branding, coherent arc, instrumental only.

A cinematic Nordic electroacoustic ballad imagined as a remote polar data center singing to itself at dawn. Deep sub bass pulses like machinery, brushed drums, bowed metal percussion, prepared piano, granular synth pads, warm analog arpeggios, and a small Icelandic vocal ensemble. Begin sparse and intimate, build into a powerful chorus with layered harmonies, then open into a wide instrumental bridge with shimmering high strings and distant radio textures. Emotional, precise, spacious, high-fidelity production, modern soundtrack feel, clear vocals, dramatic but restrained.

Transform the supplied dry narration into a polished musical e-learning clip for professional seed-vault technicians. Preserve the source speaker, exact wording, sentence order, intelligibility, timing, and recognizable speech rhythm. Turn the narrator's natural pitch contours into restrained melodic spoken-word phrasing without making the delivery theatrical. Build a precise, frost-bright electroacoustic arrangement around that cadence: soft glass marimba, muted prepared piano, bowed vibraphone, low clarinet breaths, and a quiet mechanical pulse suggesting refrigeration equipment. Let short instrumental figures echo the narration's original rhythm and melodic inflections, with subtle emphasis on each required action and a gentle harmonic lift for the emergency transfer instruction. Calm, authoritative, spacious, scientifically credible, and suitable for an internal compliance course. Keep the voice centered and close, with music clearly beneath it. End cleanly after the final instruction.

Three-minute cinematic electro-acoustic cantata inspired by a skyborne weaving guild gliding above green canyons. Start with close-mic textile loom clicks used as percussion, soft bowed vibraphone, and distant frame drums. Build into a 6/8 groove with kora arpeggios, warm analog bass, crisp handclaps, brushed cymbals, and airy modular synth pulses. Add a clear lead vocal with layered call-and-response choir, hopeful and adventurous mood, spacious production, wide stereo field, dynamic arrangement with verse, lift, chorus, instrumental bridge, final chorus, and gentle coda. Make the hook memorable, rhythmic, and singable, with natural human phrasing and no harsh distortion.
