Plugins built by a producer, for producers.
Synths, kick designers, dynamics, modulation and reverb tools — every Kajuby plugin is engineered from real production needs, not a spec sheet. Pay what you want, or grab it free.
Instrument · Drum Synth
Design hardstyle & EDM kicks from scratch.
KickForge builds a kick from five independently sculpted layers — Transient, Punch, Top Kick, Crunch and Sub — each with its own FX chain, then glues it together with master processing and a tempo-synced loop performance mode. Ships with the KickForge Library: 1,000+ curated layer samples.
Instrument · Flagship Synth
The flagship synth with no limits.
Three fully independent oscillators, each switchable between five engines, feed a dual-filter mixer, a 64-slot modulation matrix and a 3-bus FX rack with 12 effect types. 140+ factory presets included.
The big update: every Kajuby plugin now runs on Windows and macOS.
The whole lineup has been rebuilt on the latest JUCE framework. The download links stay the same: everything is on Gumroad as before. Open any plugin to see exactly what changed in its release notes.

Built in the DAW, not in a boardroom.
Kajuby is a one-person audio plugin studio. Every tool in the catalogue started as something missing from an actual session — a kick that needed more layers, a reverb that needed one more algorithm, a filter sweep that needed to feel right in one knob.
All plugins are built natively with JUCE and ship as VST3, AU and CLAP for Windows and macOS (instruments also include a Windows Standalone app). They're priced Pay-What-You-Want or free on Gumroad — because tools that help you finish tracks should be easy to get into your hands.
