How Stem:Ample works

A four-step song architect: Vision → Build → Review → Export. Choose Quick (5 cards), Standard (11 cards), or Studio (all cards) to match how deep you want to go. Each card is one creative decision — genre, mood, tempo, vocal style, production, and more. Lock the values you love, mute the ones you don't, then export a platform-tuned prompt for Suno, Udio, ElevenLabs, and more.

1. Choose Quick, Standard, or Studio at the top of the Build zone to set how many cards you need to fill.
2. Cards marked ★ Key card are the ones your chosen mode recommends — fill these first.
3. Tap Inspire Me to seed all cards based on your genre, or use Happy Accident for a random combination.
4. Lock any card to freeze its value through reshuffles. Mute any card to drop it from the exported prompt.
5. When your threshold cards are filled, the I'm Finished button glows gold — tap it to move to Review.
6. In Step 4 Export, use the Priority Zone to choose which of your cards lead the prompt, then copy for your platform.

A 4-step generator for short loop ideas — BPM, note count, key, and constraints. Outputs a platform-specific constraint line you can append to any Session prompt.

1. Set BPM and note count in Step 1.
2. Pick a key and scale in Step 2.
3. Add or remove constraints in Step 3.
4. Copy the platform-specific constraint line from Step 4.

Your Authorship Fingerprint and saved Blueprint Library. Save any Session as a named Blueprint to restore later, share, or compare across projects.

1. From the Session page, use Favorites to save a snapshot.
2. From Blueprints, you can name, describe, and tag each saved Blueprint.
3. Use the Blueprint Locker to export the full library as a JSON file.

A song decoder that reverse-engineers the creative DNA of any reference track. Enter an artist and title, and Stem:Code analyzes the song across dozens of musical characteristics — groove, harmony, production, arrangement, melody, instrumentation, and more — then lets you hand-pick which ones become your prompt. Your first decode is free. After that, Stem:Code is a Pro feature — upgrade any time to keep decoding. Use the Simple/Studio dial at the top to switch between a clean, guided view and the full detailed workspace.

1. Enter an artist name and song title in the search bar, then hit Run Sequence Decode.
2. The DNA Builder auto-selects the strongest 15 characteristics for you — nothing is exported until you say so.
3. Use the checkboxes, Creative Goal presets, or one-click Keep filters (Groove, Production, Vocal Style, etc.) to curate exactly what you want.
4. Copy a ready-made prompt for Suno, Udio, Stable Audio, MusicFX, Riffusion, or ElevenLabs — or copy the Studio Brief for a full written breakdown.
5. Hit Save to Locker to archive the full decode result for later reference.

One JSON file that contains your entire workspace — current Session, all favorites, all history, Loop:Seed favorites, Blueprint metadata, and Stem:Code library. Owned by you, stored on your device.

1. Click the gold Locker button (top right) → Export JSON.
2. Back up the file anywhere — Dropbox, iCloud, your masters folder.
3. On any device, open Stem:Ample and use Load JSON to restore.
4. Cloud sync is live for Pro subscribers — your workspace syncs automatically across devices. Free tier still works great with manual Locker export/import.
