DUBNATOR · CONTROL TOWER
LIVE
IN THE DANCEFX-01 · ISOLATOR
One channel strip. A full dubplate arsenal.
Isolator, decks, two EQs, reverb, tape echo, dub filter, siren and a 12-slot sampler — every module wired into a single signal path you can rebuild on the fly.
DECKS A / B
Dual decks + smart playlists
Load MP3, M4A, WAV, AIFF or FLAC. Drag-drop playlists with search, queue and auto-advance, plus rewind modes, hot-cues, beat-loops and a crossfader with selectable curves.
DUAL EQ
10-band graphic + 4-band parametric
A 10-band graphic EQ with shape presets stacked beside a 4-band parametric, wired through a single routing selector.
REVERB
Cavernous reverb processor
Send/return, room, HF-damp, dry-wet, pre-delay and FREEZE for an infinite tail. Modulation, an interactive band-pass graph and a dedicated limiter.
TAPE ECHO
Type 1 / 2 tape delay
Saturation, feedback, wow & flutter and ROBOT mode. Tempo-sync, interactive filter graph, sub-HP and its own limiter to tame runaway feedback.
DUB FILTER
Hands-free dub-wah
HP/LP with cutoff and resonance, plus an auto-sweep LFO that rides the filter for you. Route it anywhere in the chain.
DUB SIREN
Floating dub siren
Oscillator with two LFOs, bit-crusher, stereo auto-pan and a 12-slot preset bank. Echo and reverb sends in a detachable floating window.
SAMPLER · 12
12-slot sound-system kit
Air horn, siren, gun-fingers, wheel-up, laser, sub-drop, horn-stab and more. Reverse, hold, drag-drop replace, FX sends and save/load sets as .zip.
MASTER · METER · REC
Master, metering & recorder
Master gain, mono, dim and rumble-HP with peak metering. Three limiters with live gain-reduction. Capture the mix and export to WAV or AIFF.
TOTAL MIDI CONTROL
Every knob and fader is mappable.
Cmd + Shift + click any control to MIDI-learn it. Pickup mode keeps moves glitch-free, and you can save or load full mappings per rig.

Open-source100% local
Is it free?
Yes. Dubnator is free and fully open-source — no account, no paywall, no upsell. Run it, fork it, ship a build. Source and releases live on GitHub.
Does my audio leave my machine?
No. Every band, every effect, every meter runs locally through Web Audio in your browser. Nothing is uploaded, streamed, or phoned home — your mix never leaves the dance.
Do I need a MIDI controller?
No — the whole rack is playable with mouse and keyboard. But every knob and fader is mappable: Cmd+Shift+click any control to MIDI-learn it, with pickup mode and save/load mappings when a controller wants hardware under its hands.
Which browsers are supported?
Any modern browser with Web Audio — Chromium, Firefox, and Safari are all good. For multichannel and live input, desktop Chrome gives the most reliable routing and lowest overhead.
What audio formats can I load?
Drop in MP3, M4A, WAV, AIFF, or FLAC. Load both decks, build per-deck playlists, and queue tracks straight from your library.
Browser or desktop app — what's the difference?
Same rack, same controls. The browser version is instant and installable as a PWA. The desktop build (Tauri, for Windows / macOS / Linux) adds a native window, full offline use, and lower latency.
