The gap this workflow fills
Search results for AI stem separation are dominated by DJ mix tools, production utilities and product comparisons. That helps if you only need cleaner audio. It does not explain how to use separated stems to run a live visual show. This page is for DJs, VJs, bands and livestreamers who want stems to become visual triggers.
Best stem-to-visual routing plan
- Split the track into practical groups: drums, bass, vocals and music bed are usually enough. Too many stems creates noise and more failure points.
- Choose the visual role for each stem: drums can drive cuts and flashes, bass can drive scale or pulse, vocals can reveal lyrics, masks or camera layers, and the music bed can control color drift.
- Normalize levels before showtime: avoid one loud chorus causing every visual layer to max out.
- Keep a full-mix fallback: if a stem file fails or routing changes, REACT can still follow the main audio feed.
- Test silence and breakdowns: make sure the system looks intentional when stems drop out.
Recommended show setup
- DJs: prep stems for headline tracks, then use the live master output for transitions and unprepared requests.
- Bands: route kick, vocal and backing track stems separately when available. Use the room mic or interface feed as backup.
- Livestreamers: keep CPU headroom. Stem playback, OBS and real-time visuals compete for the same machine.
- VJs: map only the stems you can explain to the artist. Simple mappings are easier to troubleshoot under pressure.
Where REACT fits
REACT turns audio into live visuals without requiring a full VJ programming rig. With separated stems, you can make the show feel more intentional: percussion can control motion, vocals can control focus, and bass can control impact. Start simple, save presets per set, and keep a fallback scene ready.
