Rubbadub
Key Features
- Tempo sync keeps dub-style repeats aligned with a host project.
- A state-variable filter in the feedback path shapes each successive echo rather than only the dry input.
- High, medium, and low time modes cover short coloration through longer delay settings.
- A keyboard modifier enables finer delay-time adjustment where extra precision is useful.
- Very short delay times turn the effect into a through-zero flanger.
- Depth, rate, and shape controls add modulation for pitch movement and more unstable textures.
Description
Rubbadub is a legacy delay effect from ++Audio that combines tempo-synced dub repeats with a state-variable filter placed in the feedback path. Its compact interface is aimed at shaping echoes into darker, more resonant, or more animated textures instead of simply repeating the input unchanged.
Three time ranges—high, medium, and low—give the delay control a broader working span, while finer adjustment is available from the keyboard modifier described by the developer. That makes it suited to moving between short coloration and longer rhythmic repeats without relying on a large multi-page interface.
At very short delay settings, Rubbadub changes role into a through-zero flanger. The modulation controls can then push it toward pitch movement and rubbery, unstable effects, making it useful for sound design as well as dub-style feedback processing.
The developer still hosts direct Windows VST and Mac VST/AU downloads on the individual Rubbadub page, with no payment or account step shown. This is an older release: the Windows archive is explicitly named as a 32-bit alpha build, so test it in a compatible legacy host before depending on it in a current production setup.

Frequently Asked Questions
Is Rubbadub only a delay?
No. The developer says that at the shortest delay-line settings it becomes a through-zero flanger. Its modulation controls therefore support both repeat-based effects and moving, pitch-shifted coloration.
Can Rubbadub lock its repeats to the session tempo?
Yes. The ++Audio product page describes Rubbadub as a tempo-synced dub delay. It also uses high, medium, and low time modes for detailed delay-time control.
How is the feedback tone shaped?
Rubbadub places a state-variable filter in its feedback line. This lets the delayed signal be filtered as it repeats, which is useful for darker or resonant dub-style feedback sweeps.
Will Rubbadub work in a modern 64-bit DAW?
The product page provides a Windows VST archive whose filename identifies it as a 32-bit alpha build, plus a Mac VST/AU bundle. ++Audio does not publish current operating-system, 64-bit, or Apple Silicon compatibility claims on that page, so use a compatible legacy host and test before relying on it.
