Fragmental
Key Features
- Six patchable effects — delay, granulator, reversinator, and three phase vocoder modes (Transpose, Exaggerate, Spectral Accumulation) — all routable in real time
- Flexible serial/parallel/hybrid routing matrix lets you reconfigure the effects chain on the fly for instant sound design experimentation
- Three modulation sources with pie chart-based routing, including host-syncable LFOs with adjustable frequency ranges
- Phase vocoder processing derived from University of Bath PVOC research enables spectral transposition, exaggeration, and accumulation effects
- 105+ factory presets spanning ambient textures, rhythmic glitches, and extreme sound mangling — some presets are intentionally loud
- Open source (MIT license) with full C++ source code available for developers to study or modify
Description
Fragmental by NDC Plugs is a complex multi-effects VST plugin that combines a delay, granulator, three phase vocoder effects, a reversinator, and three types of modulation source into a single patchable signal chain. Developed by Niall Moody in collaboration with shamann from the KVR Audio community, it was designed for experimental sound mangling and FSU (Fuck Stuff Up) production.
The six effects can be freely re-routed in real time between serial, parallel, and hybrid configurations using a flexible routing matrix. The three phase vocoder modes — Transpose, Exaggerate, and Spectral Accumulation — are derived from the University of Bath's PVOC research, enabling spectral processing that reshapes harmonic content in unpredictable ways.
Modulation routing uses an intuitive pie chart representation, with three modulation sources including LFOs with host sync and adjustable frequency ranges. The combination of granular fragmentation, spectral processing, and time-based effects creates textures ranging from subtle ambient washes to full-on glitch chaos.
Fragmental has earned a 4/5 rating on KVR Audio, where reviewer john glossenger called it "a good multi-FX for FSU exploration" and praised the real-time routing flexibility. YouTube creator Beats Basteln named it their "favorite FSU plugin" in a 2025 dedicated showcase.
The plugin introduces a constant latency of 7680 samples due to the phase vocoder FFT processing, though PDC-capable hosts compensate automatically. The source code is available under an MIT-style open source license.

Frequently Asked Questions
What is a multi-effects VST plugin?
A multi-effects plugin combines several audio effects — such as delay, reverb, distortion, filtering, and modulation — into a single interface with flexible routing. Fragmental goes further by including spectral processing (phase vocoders) and granular effects alongside traditional time-based effects, all patchable in serial or parallel.
What is FSU in music production?
FSU stands for 'Fuck Stuff Up' — a category of plugins designed for extreme, unpredictable sound mangling rather than transparent mixing. FSU plugins like Fragmental use granular processing, spectral manipulation, and buffer effects to transform audio into glitchy, textural, or chaotic results.
Does Fragmental work with modern DAWs?
Fragmental is a 32-bit VST plugin for Windows. It works in any VST-compatible DAW, though modern 64-bit-only hosts may require a bridge like jBridge or 32 Lives. The plugin was last updated to version 1.02 and ndc Plugs has discontinued active development.
What is the latency of Fragmental?
Fragmental has a constant latency of 7680 samples caused by the FFT processing required for its three phase vocoder effects. DAWs with Plugin Delay Compensation (PDC) will automatically compensate for this, so timing stays aligned in your project.
What are the best paid alternatives to Fragmental?
Output Portal ($149) is a highly-rated granular effects plugin that transforms audio through granular synthesis with musical results. Sugar Bytes Artillery2 ($129) is a multi-effect keyboard plugin with 28 effects including granular, vocoder, and loop processing — similar to Fragmental's approach of combining spectral and time-based effects.
