These are JSFX plugins for Cockos REAPER.
These effects were written with the help of Claude AI. What started out as a simple learning exercise turned into madness! I'm using these in my own projects and very happy with the results.
- Install ReaPack if you haven't already
- Add this repository: https://raw.githubusercontent.com/keithhanlon/citizenkeith/master/index.xml

Fidelio is a channel strip plugin combining transformer-style harmonic saturation, a Neve-inspired high shelf EQ, a Trident-style high-pass filter, two parametric mid bands, and a dynamics section with compressor, expander, and gate modes.
An emulation of the Cooper Time Cube, a classic electromechanical delay unit that created its characteristic doubling effect by sending audio through a coiled garden hose as a transmission line.
This plugin is inspired by Frippertronics, Robert Fripp's tape delay technique that utilized two Revox tape machines to create repeated delay.
Tycho Delay is a tape delay emulation that provides vintage tape characteristics. Version 2 includes a complete GUI overhaul, DSP fixes, a dedicated tempo sync on/off toggle, ping pong stereo, and an optimized memory.
Emulation of the Watkins WEM Project V Fuzz pedal, a sophisticated 8-transistor British fuzz from the late 1960s.
VintageWarmer-inspired compressor with optional 2x oversampling via a 63-tap halfband FIR filter.
Upward compressor inspired by analog FM radio processing. Boosts quiet passages while leaving loud peaks untouched.
SSL/Sonitus-inspired glue compression for mix bus duty.
A fast vocal leveling tool with minimal controls, inspired by the workflow of the Waves R-Vox.
The Probabilistic MIDI Generator creates evolving, generative MIDI patterns using probability-based algorithms. Perfect for ambient music, experimental compositions, modular-style sequencing, and improvisation.
Insert it before any MIDI instrument in REAPER, and watch as it generates note sequences that never repeat exactly the same way twice.
- Insert the plugin on an empty track before a MIDI instrument
- Choose your key with the ROOT knob (60 = C4)
- Select a scale using the large SCALE knob
- Set pattern density with the TRIGGER knob (70% is a great starting point)
- Adjust pattern variation with REPEAT (50% balances repetition and change)
- Hit play and hear your generative sequence come to life!
From there, experiment with:
- VEL RND and DUR RND for more organic, human-like expression
- STEPS to change rhythmic subdivision (4 = sixteenth notes, 8 = thirty-second notes)
- LENGTH to extend or shorten your pattern phrases
- OCTAVES to expand or narrow the melodic range
Tempo-synced stereo tremolo with morphing wave shapes.
Inspired by the Schulte Compact Phasing "A" (ca. 1973, West Berlin). Known as the "Krautrock Phaser", it was used by Kraftwerk, Tangerine Dream, Conny Plank, Klaus Schulze, Pink Floyd, and others.
Cloudbusting Reverb is an algorithmic reverb inspired by the Cloud Seed Reverb, using parallel comb filters and cascaded allpass diffusion to create rich, modulated spaces ranging from tight rooms to vast ambiences.
Stereo widener, BBD chorus, ping pong delay and three reverb choices, for a Robin Guthrie-inspired tone.
SynthiAKS (rhymes with "maniacs") is an emulation of the EMS Synthi AKS modular synthesizer, known for its unique pin matrix patching system and distinctive analog sound, used by artists like Pink Floyd and Brian Eno.
TapeEmu is a tape machine emulation plugin designed to add the warmth, character, and sonic artifacts of classic analog tape recording to digital audio. Features include harmonic saturation, tape hiss, low-frequency head bump, stereo width control, and tape aging effects like dropouts and wow & flutter.
