Grab the thing.

No installers, no ceremony. Each zip below is exactly one file — unzip it, drop it where your DAW looks, done. Free builds run in demo mode; a license key unlocks saving and export.

Your OS will warn you. That’s expected.

These builds are ad-hoc signed — no Apple Developer ID, no Windows code-signing certificate. That money went into DSP instead, and the binaries are fine. The warnings are about who didn’t pay, not about what’s inside.

macOS — “damaged” or “unidentified developer”: right-click the app and choose Open, or System Settings → Privacy & Security → Open Anyway.
Windows — SmartScreen “unrecognized app”: More info → Run anyway.
Linux — no ceremony; nobody to pay.

Plugin formats mostly slide straight into a host — the warnings usually hit the standalone app.

RUB v0.1.2

latest27 October 2026

The plugin polish release. A smarter plugin window, real host tempo following, and a cleaner look for the glowing LEDs.

What's new

Collapsible sequencer (plugins). Switch the sequencer card off with its LED and the window shrinks to a slim keyboard strip — a wide multi-octave keyboard, with the MIDI map, Song JSON and shortcut icons stacked beside it. Sequencer-only keys and the play button step aside while it's off.
Follow Host. The new Follow Host control (plugins only) makes RUB take its tempo and play/stop state from your DAW. The BPM field shows the host tempo and locks while it's on; with the sequencer off it simply keeps the delay in time.
OPTS menu in every format. License, Import Presets, About and Reset are now available in plugins too (Audio/MIDI Settings and Quit stay standalone-only).
Clearer parameter names in your DAW. Automation lists now read "Filter Cut Off", "Osc A x2", "Delay Sync", "Seq Slide Gate" instead of bare names like "x2" or "Accent".
Smoother LED glows. Lit LEDs now glow with a soft, round halo that is no longer clipped by neighbouring controls.
Dialogs fit any window. Song JSON, MIDI map, About, License and the shortcuts popover now stay inside short windows and scroll when they need to.
Fixes for plugin hosts. No more rounded window edges inside your DAW, and keyboard shortcuts can no longer hijack typing into text fields (like the license key) while a dialog is open.
Shortcut tweaks. Accent is now , and Slide is ., matching the button order in the step grid; the shortcut list adapts to whether the sequencer is on.

Unsigned builds

Same as 0.1.1 — these are unsigned, so macOS Gatekeeper and Windows SmartScreen will warn. That's expected; right-click → Open (macOS) or More info → Run anyway (Windows).

Where to drop it

Plugin bundles are folders — unzip, then move the whole RUB.<format> folder into place.

macOS: Standalone: wherever you like (drag it to /Applications). Plugins: ~/Library/Audio/Plug-Ins/Components (AU), ~/Library/Audio/Plug-Ins/VST3, ~/Library/Audio/Plug-Ins/CLAP, ~/Library/Audio/Plug-Ins/LV2.
Windows: Standalone: anywhere. Plugins: C:\Program Files\Common Files\VST3, ...\CLAP, ...\LV2.
Linux: Standalone: anywhere — chmod +x RUB if it won’t run. Plugins: ~/.vst3, ~/.clap, ~/.lv2.

Older versions

RUB v0.1.126 October 2026

The preset bank update. Every format on every OS now ships with the full factory bank compiled in — no separate preset files to install or lose.

What's new

35 factory presets, embedded in every binary. Standalone, VST3, CLAP, LV2 and AU all carry the complete bank; presets can't go missing no matter where the plugin file ends up.
Reworked bank. Seven new presets joined the factory set (Clickscream Fast/Slow, Craw, Fourss, Going, M2, Draum) and the whole list was renamed and reordered — it now opens with the signature sounds.
Safer saving. Factory presets are read-only in release builds — saving over one creates your own user copy instead of modifying the original. Saving a preset or MIDI map with a name that already exists appends upd.N automatically instead of shadowing it.

Unsigned builds

Same as 0.1.0 — these are unsigned, so macOS Gatekeeper and Windows SmartScreen will warn. That's expected; right-click → Open (macOS) or More info → Run anyway (Windows).
