Three controlled experiments
A voice over B, B voice over A, then a no-collision phrase-matched drop swap. The engine never returns three cosmetic crossfades.
Version rack
Three arrangements.
No random crossfade.
Each version follows the bar grid and has a different structural idea. If the sources do not fit, Mashups refuses the pairing instead of shipping noise.
01 / 03
A Voice / B Body
A's topline enters after a two-bar runway over B's groove.
02 / 03
B Voice / A Body
B's topline takes the inverse test over A's rhythmic body.
03 / 03
Drop Swap
A owns the setup; B lands on bar nine with no overlapping toplines.
The handoff
Keep it. Fork it. Start the chain.
Export a 15- or 30-second vertical video carrying both source passports and permanent Mashups attribution. Standalone audio and stems never leave the Green Room.
Keep one arrangement to unlock the watermarked video renderer.
Next chain
Publish the attributed project after sign-in.
The project stores arrangement parameters and source lineage, not a detached downloadable master.
Closed source pool
Only Mashups originals and verified contributor tracks enter this deck.
Permission travels
MASH-GREEN-0003 and MASH-GREEN-0002 stay attached to every render.
Exact scope
Only watermarked 15/30-second videos may leave this prototype; no WAV, MP3, stems, paid media, or DSP distribution.
