Intelligent music workstation
Understand your track.
Work the section that matters.
Stay in control.
StemSense pulls your song apart, lets you talk about any section out loud, and generates ideas that actually fit your key, register, and feel — not generic MIDI, not AI slop.
Reach up — voicing in the upper register
How it works
01 · Understand
See your whole song at once
Upload a track and StemSense separates it into six stems — vocals, bass, drums, guitar, piano, and other — then maps key, tempo, sections, chords, and note events across every layer.
02 · Work the section
Talk about the exact part that matters
Draw a region on any stem and ask. The agent answers from measurements taken off your actual audio — onset counts, register, harmony, rhythm — never from generic music theory.
03 · Stay in control
Get options that fit — not output
Every idea is scored against your track’s key, register, rhythm, and harmony before you ever see it. Each option ships as playable audio, real notation, and a MIDI file for your DAW.
Every idea is checked against your track before you hear it
StemSense measures first, then generates — and only surfaces what survives.
Grounded
Deterministic measurements run before any model call. The agent states facts, not guesses.
Verified
A two-model firewall reads the numbers, then speaks — so claims about your track can’t be invented.
Filtered
Every generated option is scored and judged. You only hear the ones that fit.
Watch
A real session, start to finish
Upload, stem separation, a spoken question about a crowded chorus, and three generated voicings dropped straight into a DAW.
Engineering
How it was built
The stem-separation pipeline, the real-time voice agent, and the constraint system that keeps generated ideas honest.
