Chords that sit in the room.
Play one key and the Underground Engine voices a whole dub chord — then you ride DUB, SPACE and TONE while a 16-voice engine breathes underneath. Built for deep / dub techno and minimal, not for EDM drops.
- 62 factory presets
- 7 chord shapes, 3 voicing controls
- MIDI out + clip drag-out
- No iLok, offline activation

AMBIENT
Not a demo loop. The engine.
Three clips below were rendered straight out of the plug-in — same engine you get, nothing re-recorded or mastered afterwards except a −1 dB peak normalise.
Dub stab
preset “Concrete Echo”Short stabs into a long room. TONE closes while SPACE widens, then a dub throw into the tail.
Ratchet arp
preset “Ratchet Sync”The same chord engine as sixteenths: ratchet, accent and a synced tremolo on top.
Four things it does that a preset bank can’t
Voicing, not just chords
Seven dub shapes (m7, m9, m11, sus2, sus4, add9, inverted dub) and three controls that change how they are stacked: INVERSION walks the bass tone up an octave, VOICES thins a five-note m9 down to a triad, DROP 2 drops the second highest tone for that open, slightly jazz voicing.
Macros that rewrite every preset
DUB, SPACE and TONE are real automation parameters (−1 … +1) that offset whatever preset is loaded. One automation lane sweeping SPACE opens the room of all 62 presets with the same musical curve. They survive preset changes, so DICE never yanks a macro you ride.
The chord leaves the plug-in
MIDI out sends the generated chord (or chord + played notes, or played only), and the MIDI pill drags a ready-made clip into Live, Logic, Cubase or Reaper. Layer your own bass, piano or a hardware synth under the same harmony.
A dub chain, not a test bench
Tempo-synced delay with filters inside the feedback loop, a dark space reverb, master low-pass, tape drive and width. Two tempo-synced LFOs breathe on the cutoff and the delay feedback; DUB DLY / DUB VRB are throw buttons for dub-mixer gestures.

FAQ
What exactly do I get after paying?
A licence key for your name + e-mail and the installer download. Paste the key into the About window (click “UNDERGROUND ENGINE” in the top bar) — the trial badge turns into “FULL” and saving your own presets unlocks. No account, no dongle, no phone-home on every start.
How does the trial differ from the full version?
For 14 days everything works: all presets, all macros, MIDI out, clip drag-out. After that the engine keeps making sound, but you cannot save user presets until you licence it. We deliberately do not mute audio or inject noise — that would just ruin your session.
Is it Apple Silicon native?
Yes — one universal binary for Intel and Apple Silicon, macOS 10.15 and newer. Windows 10/11 is x64.
Does it work as a MIDI effect?
It is an instrument with MIDI out. To drive another synth, put it first in the chain and set MIDI Out to “Chord” or “Chord + played”. The MIDI pill also drags a clip straight into your DAW.
Can I use it in commercial releases?
Yes, royalty-free. You may not resell the plug-in, the presets as a product, or reuse the factory bank inside your own soundware.
Refunds?
14 days, no questions asked — the licence is deactivated and the money returned. Just mail the order number.
Which DAWs are tested?
Ableton Live 11/12, Logic Pro, Cubase, Studio One, Reaper and Bitwig. If something misbehaves, send the host + version — we answer.
