CREATIVE FREEDOM

Conservative preserves straightforward phrasing. Creative varies entrances and breakdowns. Experimental takes greater structural risks.

02Loop library

0 SOUNDS LOADED

Import 4 / 8 / 16 / 32 / 64-bar loops. Files stay on your device.

Loops should already match the selected BPM. No time-stretch, EQ, compression, reverb or mastering is applied. Length mismatches are flagged instead of being silently corrected.

DESCRIBE THE ARRANGEMENT

This first version interprets energy words, named stems, intro preferences and final kick replacement. Complex instructions may need manual timeline edits; no cloud AI is connected.

FINAL KICK REPLACEMENT

FINAL PHRASE

INTRO

Import loops, then generate your arrangement.

05Clip editor

NON-DESTRUCTIVE

Select a block on the arrangement timeline to edit it. You can move, extend, shorten or remove clips without changing their source audio.

06Reference track

YOUTUBE + LOCAL

YOUTUBE VIDEO URL

Paste a video link to load a reference player.

YouTube can be played and referenced here, but its raw audio cannot be analysed from a URL. Some videos disable embedding. For automatic energy analysis, import an audio file you have permission to use.

REFERENCE AUDIO FOR ENERGY CURVE (OPTIONAL) Use reference energy pattern when arranging

REFERENCE STRUCTURAL MARKERS

Annotate moments from the YouTube video manually. These markers are saved with the project; audio is never extracted from YouTube.

PREVIEW MIX LEVEL 50%

Affects auditioning and the optional mixed preview WAV only. Individual stems are exported at original levels.

ALIGNED FULL-LENGTH STEMS

Each stereo WAV starts at bar 1, includes silence where the stem isn't playing, and ends at precisely the same sample. No effects, normalisation or automatic mastering. Existing sample rate differences require basic resampling. Long songs produce large files on iPhone.
