Watch it work.
A short walkthrough of Stemio in real use. Stems coming in, auto-sorting into types, and mix presets rendering on the fly. The fastest way to see whether it fits your workflow before joining the waitlist.

Three sample stems. Solo a lane, render a preset, hear the mix version generator in action. Instrumental, vocal-only, sync-ready alternates. This is roughly what working in Stemio's stem mixing platform feels like, no signup or upload required.
