# AI Track Generator Add vocals or instrumental layers to an existing source track with style guidance and avoid-list controls. > Canonical: https://aimusicis.com/ai-track-generator ## Finished instrumentals, six briefs Complete tracks rather than loops, each written to a different brief. Nothing here needs a vocal to make sense. ### Progressive Layers Eight minutes of build where each layer enters on a 16-bar boundary. ### Battle at the Bridge String ostinato with timpani and low brass, pushing from 120 to 144 BPM. ### Jazz Funk Session A head, a Rhodes solo, a 7/4 bridge, then back to the groove. ### Melodic Techno Arc An arpeggio opening across eight minutes into a full pad. ### Forest Dawn Chorus Field-recorded birdsong under a slow pad, no rhythm at all. ### Texas Jam Overdriven Strat at 118 BPM, twelve-bar with a double-time turnaround. ## Add new layers without replacing the song AI Track Generator starts from an existing audio source and adds the missing part: vocals, harmonies, instruments, or backing layers that fit the original track. ### Choose what to add Switch between Add Instrumental and Add Vocals before submitting so the model understands the production job. ### Describe the backing style Use the style and instruction fields for instruments, energy, genre, vocal direction, and arrangement intent. ### Avoid bad fits The avoid-list field helps steer away from unwanted sounds, styles, instruments, or vocal traits. ## How to add tracks with AI Use the page when a song has a strong core but needs added vocals, instruments, or arrangement depth. ### Pick a source Upload a track or choose one from My Music. The generator validates that a source exists before spending a generation. ### Choose vocals or instruments Select Add Vocals for singing or harmony layers, or Add Instrumental for backing parts and arrangement support. ### Write the style brief Describe the layer you want and list any styles, instruments, or vocal traits to avoid. ### Finish the result Use stem separation, mastering, covers, or visualizers when the enhanced track is ready. ## Controls for adding vocals and instrumentals The generator keeps source selection, layer type, backing style, and avoid-list controls in one focused flow. ### Add Instrumental mode Generate backing layers that fit the existing source song instead of replacing it. ### Add Vocals mode Create vocal or harmony layers for tracks that need a topline, hook, or vocal texture. ### Avoid-list guidance Tell the generator which instruments, styles, or traits should stay out of the added track. ## A beginning, and somewhere to end ### 3 moments A track needs: a way in, a peak and a way back out. ### 1 length decision Length changes the arrangement more than any instrument choice. ### 0 editing No editing is needed afterwards if the structure was named at the start. ### 6 upload formats MP3, WAV, OGG, M4A, FLAC, AAC - accepted when a reference sets the arc. ## Who generates finished instrumentals ### Content teams on a deadline A brief in, a finished instrumental out, with no session to book and no library license to check. ### Producers sketching an arrangement Hear a full instrumental of an idea before committing a day to programming it. ### Game and app developers Score menus, levels and trailers from one consistent palette rather than stitching stock tracks together. ## Tools related to AI Track Generator ### [AI Music Generator](https://aimusicis.com/ai-music-generator) ### [AI Music Generator With Vocals](https://aimusicis.com/ai-music-generator-with-vocals) ### [Text to Song Generator](https://aimusicis.com/text-to-song-generator) ### [AI Text To Music](https://aimusicis.com/ai-text-to-music) ## AI Track Generator FAQ Answers for creators adding AI vocals or instrumentals to existing audio. ### What is AI Track Generator? The AI Track Generator adds new vocal or instrumental layers to a source track while keeping the original song as the foundation. ### Can I use a saved Aimusicis song? Yes. You can paste an uploaded source URL or choose a finished track from My Music. ### What should I put in avoid elements? List instruments, genres, vocal tones, or production choices that would clash with the source song. ### Is this different from remixing? Yes. Remixing transforms the arrangement; add-tracks keeps the source and adds supporting vocals or instrumental layers. ### How do I get a real ending? Ask for one. Left unspecified, arrangements tend to fade or stop rather than resolve, and a resolved ending is what makes it feel finished. ### Should I specify a length? If the track has a job - a video, a set, a slot - yes. If you are exploring, leave it open and let the arrangement find its own shape. ### When should I fill in avoid elements? After a run rather than before the first one. List whatever kept turning up that you did not want; as a guess up front it is mostly noise. ### Can I use the AI Track Generator for commercial projects? Aimusicis does not currently issue a commercial-use license or certificate. Download access is separate from usage rights; review the current Terms and confirm you hold the rights to every uploaded or referenced source before publishing. ### What should I do after using the AI Track Generator? AI Mastering, AI Music Visualizer and AI Stem Splitter are the usual next steps. Results stay in My Music, so what you make here can be picked up in any of them without re-uploading it. ### How many credits does AI Track Generator use? AI Track Generator draws 5 credits per run. New accounts start with 10 free credits, and every plan and pack is priced in the same credits. ### What are the input limits for AI Track Generator? In simple mode the description is capped at 500 characters. In custom mode lyrics run to a maximum of 5,000 characters, depending on the model version. The style field accepts up to 1,000 characters (200 on V4 and V3.5), and the title up to 80. Finished songs download as MP3 files. ## Add tracks with Aimusicis Upload a source song, choose vocals or instruments, and add the missing layer in one connected AI music workflow. _Last updated August 28, 2026_
