The now-line
What's playing, and why
A single readout under the dial names what's sounding right now — source, key, BPM, mood — and, in plain language, why: where you are in the arc, what's building, what just changed.
Describe the set in a line, or just turn the dial. Oto realizes it live — and the full mixer is always one step away when you want your hands on it.
A prompt, a dial, four directives. That's the whole front door.
Type what you're hearing — 3am basement, dark and hypnotic, build slowly — or skip the words and turn the dial. Four directives shape the room in real time: Energy, Darkness, Tension, Risk. Nudge any one and the set responds. Leave it alone and the set clock drifts the energy along a planned arc, so the night evolves on its own until you reach back in.
The same dial drives whatever you point it at.
A generative engine that plays the moment you arrive — no files, no setup. Piano, chords, and arps shaped live by the four directives. The fastest way to hear the idea.
Drop audio straight onto the surface. Oto reads BPM and key, matches to the zone you're directing, and auto-mixes deck to deck with beat-aligned crossfades and bass swaps.
Connect a generative music model running locally and steer it from the same dial. The directives become the prompt; the model answers in real time.
Direction only works if you can see what it did.
A single readout under the dial names what's sounding right now — source, key, BPM, mood — and, in plain language, why: where you are in the arc, what's building, what just changed.
A compact strip shows what's queued — matched tracks when you've loaded a set, or the planned zone journey when the set clock is running. No black box, no surprises.
Pull up everything you've saved without leaving the surface. Search by name, by BPM (124 or 120–130), or by key (Am). Tap a track to load it.
Open the mixer ↗ rolls the surface up to reveal the full dual-deck controller — and drops you on the deck that's playing. Take over by hand anytime; come back to the dial when you're done.
When you open the mixer, this is what's been running the whole time.
Not what you play — how you play it. A living portrait built from your session history: dominant technique, transition speed, energy-arc tendency, BPM range, harmonic preference, mood-grid home territory. It surfaces patterns you didn't know you had, and tracks how they shift over time.
A safety net that sounds like you, not a generic fallback. Ghost draws on everything Style DNA has learned — your timing, your EQ habits, your phrasing — and executes a transition the way you would have. Hold to hand off; take back manual control at any point.
Your library mapped to a 2D emotional space — energy on one axis, mood on the other — from 11 audio features (spectral centroid, harmonic tension, tempo feel), not tags or metadata. Drag a selector to browse by feeling. A look-ahead layer flags jarring contrasts before you commit.
Split any track into four stems in real time with STFT spectral masking: bass, vocals, drums, melody. Mute the vocals, solo the drums, adjust each independently — or drag the vocal from one deck onto another deck's instrumental for a mashup that doesn't exist on record. No upload, no wait.
Go live over WebRTC, or start a B2B session — two DJs, each on one deck, synced across devices and time zones. Open practice rooms let others watch your mixer state and leave timestamped annotations that appear in your post-session review.
Eight full-screen audio-reactive shader modes — Rings, Particles, Fluid, Fractal, Tunnel, Terrain, Galaxy, Kaleidoscope — with bloom, chromatic aberration, and film grain. Smooth envelope-following reactivity. Save and share custom presets.
Everything you'd expect from pro DJ software — already here.
Before the dial, before the intelligence, Oto is a fully functional dual-deck controller. It runs entirely in your browser — no download, no plugin — in Chrome, Firefox, Edge, and Safari.
The human is always the author. The AI is the instrument.
