A DAW surface
over the actual code.

Drag a note, draw a curve, swap an instrument — the document rewrites itself underneath, and you never have to look at it. Or open it and edit the line directly. Both are the same edit, in the same history, with the same undo. What you touch locks; the studio's agents keep working around it. How the language works →

ARRANGER BUILDING

Briefs in, structure out

"Longer intro, later drop, darker middle eight." The arranger recomposes sections, energy arcs and transitions to your brief — at the next musical boundary, never mid-phrase.

SOUND DESIGNER BUILDING

Instruments on demand

Describe a sound — "hollow woody knock, metallic tail" — and it designs the instrument as a validated patch graph, or renders a sample kit from a recipe, mid-session, in under a second.

MIX ENGINEER BUILDING

Reference-measured, not vibes

Gain staging, spectral balance and dynamics are scored against profiled reference records — the same measurements a mastering engineer reaches for, continuously evaluated.

every agent writes validated musical code · every change lands on the grid · nothing touches your locks
The studio at work BUILDING

Agents propose. The grid decides.
You can lock anything.

hover a live code line below — its lane lights up. Same session, same state.
The rule that makes it yours

Anything you touch is locked from every agent
until you release it.

Your bassline stays your bassline while the studio keeps working around it. Every change — yours or an agent's — is an invertible diff in the session history. Undo is exact.

Two views. One document. BUILDING

The tracks you drag and the code streaming past are the same thing seen twice — real values from the engine, bar by bar, not a visualization of one. Move a note and the line changes; change the line and the note moves. Tap, edit, hear it next bar. It is also the same language the agents write, so directing them and editing yourself are one continuous skill — and watching it is how you learn to read it.

SESSIONS ARE FILES NOW

Portable, executable compositions

Every session is readable JSON — save it, share it, re-import it, replay it bit-identically. The session is the product: a portable program the engine performs.

FULL SURFACE

Grid, rack and mix — all open

Velocity-precise step editing, the full instrument rack with exact machine parameterizations, sends and automation lanes. On iPad the Pencil writes velocity with pressure; on the Mac the full keyboard drives it.

LEAVE WITH STEMS

Finish anywhere

Bounce per-track stems from the deterministic renderer, and take the full session as JSON. MIDI and automation export are on the roadmap. Kontinuum is where tracks are born — finish and master them wherever you already work.

FROM REFERENCE BUILDING

Rebuild from reference

Point the studio at a track in your own library. It analyzes structure, harmony, groove and per-stem character, picks or designs the instruments — and hands you a new editable session derived from its musical characteristics, correctable line by line. Analysis only; nothing is copied, and the audio never leaves your device.

PUBLISH A SIGNATURE

Your sound, as a product

Package the way you think — groove, harmony habits, rack, sample recipes, mix character — as a Soul. Publish it free, or license it: 80% of every use goes to you, metered by real listening, not playlist politics.

The studio is a free in-app download.

The app installs with Listen; the editing surface appears the moment you want it — no extra purchase, no separate app, same document underneath.
