A NOTE FROM THE BUILDER — 07/21/26

All five plugins are now at v1.1.0 — the biggest update yet. Building on the recent quality-of-life round, this release brings refined typography and UI polish across the whole family, and every plugin now remembers its window size and layout between sessions. On top of that, a wave of per-plugin upgrades: GrainBrain gains grain Density & Reverse controls, a per-LFO rate multiplier and an output limiter, plus fixes to the LFO on/off & sync bugs; O2 adds an input spectrum display and output limiter, with the feedback and high-drive rumble bugs squashed and Transformer mode stabilized; Halide can now lock its grain Density to your tempo for grains right on the beat. Bunka and Foldspace round it out with the same UI refinements and fixes. Grab the latest and greatest from each plugin's page — if you're on an older build, this is the one to update to. Cheers! — Brittnell | X

A NOTE FROM THE BUILDER — 07/17/26

The "quality of life" round is here — all five plugins just got updated! Every plugin now has roll-over help (click the ? in the top bar, then hover any control for a quick explanation), a resizable UI (drag the bottom-right corner, from 50% up to 200%), brighter text throughout for better legibility, and in-plugin undo/redo. Most of the family also picked up collapsible panels, so you can fold away the sections you're not using. And from the last note's to-do list: the Windows installers are now digitally signed. SmartScreen may still show its warning for a while as the new signature builds up reputation with Microsoft — "More info" → "Run anyway" still applies for now — but that should fade as clean downloads accumulate. Grab the latest from each plugin's page. Cheers! — Brittnell | X

NOTE — 07/15/26

Thanks everyone for all the unexpected attention! I am so happy to hear so many people are enjoying these plugins. When I started making these, they were really only for my own learning, fun, and enjoyment, but I had this thought that maybe others would enjoy them as well, so decided "why not just share them for free?". It was a pretty quick and impulsive decision, so along with this also come some quirks: One is the unsigned Windows installers (which I'm currently trying to resolve), and then I may have neglected to include presets before compiling (d'oh!). I'm currently working on some "quality of life" updates (roll-over help, better UI contrast, resizable UI, maybe more), so will try and squeeze some presets in there as well. Cheers, and thanks again! — Brittnell | X

FIVE PLUGINS  ·  ONE DARK STUDIO  ·  DONATION-WARE

XNULLX

A family of DSP-driven VST3/AU plugins for granular texture, saturation, beat-slicing, wavefolding, and spectral smear. Built plugin-by-plugin, obsessively, and given away — pay what it's worth to you.

THE FAMILY

Five plugins, one language

GrainBrain multiband granular plugin interface
MULTIBAND GRANULAR FX

GrainBrain

Shatter your signal into grains across independent frequency bands, each with its own LFO-driven motion, spectrum view, and gate. The deepest knob-forest in the family.

VIEW GRAINBRAIN →
O2 saturation and width plugin interface
3-BAND SATURATION & WIDTH

O2

Peak-preserving per-band saturation with real drift, feedback that pushes into self-oscillation, and a mono-compatible widener. Loud without getting small.

VIEW O2 →
Foldspace wavefolding plugin interface
PHASE MOD × WAVEFOLDING FX

Foldspace

MIDI-driven carrier pitch and pitch-tracked wavefolding across three blendable insertion points. Built for bass design, tuned for chaos.

VIEW FOLDSPACE →
Halide granular smear plugin interface
GRANULAR SMEAR + SPECTRAL FX

Halide

A grain cloud feeds a spectral smear layer in series — dissolving the sound itself into ambient fog, with musical chord-locked pitch and a freeze that never repeats.

VIEW HALIDE →
Bunka beat-slicer instrument interface
BEAT-SLICER INSTRUMENT

Bunka

Load a loop, detect the transients, and re-sequence the slices into new patterns — host-synced, pitch-preserving, with a 12-slot pattern bank and per-pad locking.
