Drop a track in. Stemulator turns it into a DAW-style mixer with every stem on a fader, the chord progression following along live, and studio-quality pitch and tempo control. Built for producers & musicians.
Musicians Mode is what stems are for. The mixer, the chord map, the tabs, the metronome — all wired together around your song.
Musicians Mode lives on top of features no other stem separator offers — the ones that make stems actually usable on stage and in your DAW.
Download the entire chord progression as a MIDI file. Drop it into any DAW and play the harmony on any synth, sample, or instrument.
Generate guitar, bass, and piano tabs directly from the chord detection. Export the whole set as a PDF — no manual transcription, no third-party tab service.
Stems land time-stretched to a clean integer BPM your DAW can snap to. No warp markers, no transient smearing.
Stemulator detects the true first downbeat and trims every stem to start there. Drop into your DAW at bar 1 and everything lines up.
