Halide — Granular Smear & Spectral Wash
A grain cloud that feeds its own spectral ghost — dissolve the actual sequence of grains, not just the source.

Halide runs a 256-voice granular cloud into a Paulstretch-technique spectral smear — in series, not parallel, so SMEAR doesn’t add a second layered effect, it dissolves the grain cloud’s own output into slowly evolving, phase-randomized spectral fog. Feed it anything: a chord blooms into an evolving pad, a vocal line sings alongside its own harmony, a drum loop dissolves into an ambient wash that keeps breathing long after the source stops. Everything — density, size, shape, pitch, feedback, motion — shapes the fog, because the fog is made of the cloud.

Core Signal Path
256-Voice Grain Cloud — density and size fully decoupled, a bipolar SHAPE control running rexpodec Gaussian expodec (swell, fog, or pluck character), and a single SEED macro that scales timing/pitch/pan jitter together as one “character” axis.
Serial Spectral Smear — the grain cloud’s own output feeds a from-scratch Paulstretch-style engine (phase-randomized FFT resynthesis, pitch-locked crossfades on every re-anchor) — stretch 1–100×, selectable FFT window from watery-small to choir-huge.
Musical Pitch Mode — flip PITCH into an interval/chord selector (14 entries: intervals, triads, sus4, 7ths, and a bright SHIMMER stack) and every grain randomly picks a chord tone, so the cloud sings a harmony around whatever you feed it — no key entry, the source is always the root.
Feedback Through the Whole Chain — repeats re-pass through the grain engine and the smear both, so FEEDBACK builds shimmer (PITCH +12) or murk (PITCH −12) with each pass, not just a repeating delay.
Freeze + Motion — freeze the buffer and let MOTION auto-scrub through it for infinite, hands-free evolving pads from a single held instant.
Built to Watch, Not Just Hear
A live buffer waveform display shows the write head, the TIME playhead, and every actual grain spawn as a blooming, fading ember — amber cooling to redscale over each grain’s lifetime. It’s not a generic meter; it’s a direct readout of the cloud actually happening in real time, including exactly what SMEAR is currently dissolving.

Highlights

Ducked, equal-power Mix — the fog displaces the dry signal rather than stacking on top of it, so both extremes (bit-perfect dry, full wash) stay pure.
Loudness-matched wet path — grain window energy and a slow servo both compensate automatically, so MIX behaves predictably at any SHAPE or SMEAR setting instead of getting quieter as the texture changes.
Pitch-locked spectral wraps — the smear re-anchors without the pitch clash that plain crossfading between differently-pitched material would cause.
BPM-syncable MOTION and FREEZE, for scrubbing and rhythmic texture work locked to the host tempo.
What It’s For
Ambient pads and evolving washes from static sources, granular vocal and lead harmonization, shimmer/murk feedback textures, freeze-and-scrub sound design, and any material that needs to dissolve into something that keeps moving after the input stops.

GrainBrain — Stereo 4-Band Multiband Granular Processor
Split it. Freeze it. Scatter it. Bleed it into the next band.
Splits your signal into independent frequency bands, then shreds each one into grains — its own LFO, spectrum view, and gate per band. The deepest knob-forest in the XNULLX family, built for players who want their hands on everything at once.

Built for texture
INDEPENDENT BAND STRIP
Split the signal across multiple bands, each with its own granular engine — sculpt highs into shimmer while keeping the low end intact.

PER-BAND LFO MODULATION
Every band carries its own modulation source, so grain density, size, and position can drift independently across the spectrum.

LIVE SPECTRUM VIEW
Watch the band split and grain activity in real time instead of guessing at crossover points.

GATING PER BAND
Keep grains from spawning on silence — each band’s gate reacts to its own signal, not the full mix.

Core Signal Path
4-Band Split — draggable bandpass filters right on the spectrum analyzer; grab a band and move it, narrow it, or disable it entirely.
8-Voice Granular Engine (per band) — grain size, scatter, pitch + pitch spread, drive/saturation, and wet/dry mix, independently on every band. Reverse and Freeze modes included.
Cross-Band Bleed — each band’s output can feed into the next (Low LoMid HiMid High, wrapping back to Low), for resonant, self-reinforcing textures that a simple per-band effect can’t produce.
Stutter Gate (per band) — a BPM-synced trapezoid envelope with attack, release, and phase offset, for rhythmic amplitude patterns that lock to the host tempo.
7-Target LFO Matrix (per band) — modulate Center, Width, Mix, Pitch, Scatter, Size, and Gate Phase simultaneously, each with its own depth and phase.
Built to Watch, Not Just Hear
The real-time spectrum analyzer isn’t decoration — band regions animate live under LFO modulation, so you can see a Center sweep or a Width pulse happening in sync with the audio. Drag directly on the analyzer to reposition a band by ear and eye.

Highlights
Ducked, equal-power Master Mix — dry and wet displace each other instead of just stacking, so blending in granular texture never gets muddy.
Global In and Out trim sit alongside Mix in the bottom bar — set levels in one place without hunting through four bands of per-band Gain knobs.
Collapsible Spectrum / Gate / LFO sections, remembered per preset, so the window stays exactly as compact or as deep as the patch needs.
Full MIDI Learn on every parameter.
What It’s For
Multiband texture design, granular pads and drones, rhythmic stutter/gate effects synced to tempo, spectral freeze composition, glitch and sound-design work, and subtle “make it feel alive” granular blending underneath a mix — GrainBrain covers the gap between a delicate texture enhancer and a full sound-design instrument.

Modular Filter/Delay. ShinRonin is a ground-up rebuild of Ronin, one of the earliest plugins we ever shipped, first released in 2003. The original paired two delay lines with a set of morphing filters and two fully patchable routing matrices, and it earned a cult following for the strange feedback networks and self-oscillating textures you could build inside it. Twenty years on, we have rebuilt it for modern systems, kept the architecture that made it worth remembering, and released it for free.

Two independent delay lines, each with tempo sync, reverse, looping, and feedback, feed a pair of morphing multimode filters that sweep continuously from notch through lowpass, bandpass, and highpass. There is saturation, two LFOs, and an envelope follower. Everything connects through two on-board matrices: a signal matrix that routes any audio source to any destination, and a modulation matrix that wires the LFOs, envelope, and incoming MIDI to nearly any parameter. It is happy doing clean stereo delays and gentle filtering, but the real fun starts when you patch a feedback loop and let it misbehave.

Skew is a non-linear reverse delay effect plugin for Mac, Windows and Linux. It constantly records the incoming audio into a buffer and plays it back in reversed chunks, rhythmically synchronizing them to the host transport. Furthermore, this algorithm warps the delay playback speed via a selection of non-linear curves, bending the pitch in interesting ways.

The delay has a unique design with three playheads – one for the feedback, two more for the playback – allowing the pitch bend effects to remain the same between feedback repeat cycles. With its meticulous calibration and wide parameter range, Skew can create multiple rhythmically-precise effects such as pure reversing, tape rewind, pitch slides, detuning, vibrato, scratching, and more.

SOUND ENGINE
Reversing delay with unique triple-playhead design with overdubbing feedback
12 different non-linear curves for warping the audio playback speed
Host transport location sync and tempo-based delay time adjustment with ultra-wide range: from 1/32 note to 16 bars
Lag filters on all continuous parameters for smooth, click-free adjustment
Supports mono › mono, mono › stereo, and stereo › stereo channel configurations

SUPPORTED FORMATS
Mac: AU/VST3/AAX for macOS 10.13 or newer (64-bit Apple Silicon and Intel)
Windows: VST3/AAX for Windows 8.1 or newer (64-bit Intel and AMD)

Dynamic Modulated Delay Set the routing and mode of modulation (Chorus/Flanger) through the purple control in the middle. Click on the small red circle inside the modulation (left) or delay (right) controls, to automate them by volume input (pink), or click again, to automate them by the LFO (yellow). Clicking again will set the control back to non-automated (red).

The central pink controls will set how quickly the assigned parameter goes up or down, in relation to the input volume. The central yellow controls will set where the LFO moves the assigned control up to, and how fast it moves (if the ‘LFO TO’ is less than the red position, it will have nowhere to move up to).
