Apps & Tools
iPHONE APP · ROOM ACOUSTICS
SonarRoom
SonarRoom uses LiDAR and your speakers to scan a room, play test tones, and build a full 3D acoustic map — sweet spots, problem areas, and exactly what to fix. Same impulse-response techniques the pros use, from your iPhone.
FREE BROWSER TOOL · DRUM MIDI
Drum Farm
Drum Farm builds complete, multi-section drum arrangements — not one-bar loops. Pick a genre and style, shape the groove, and download standard MIDI you can drop straight into any DAW. Free and runs in the browser, nothing to install.
INTERACTIVE MAP · GENRE FAMILY TREE
The Modern Music Map
Hundreds of genres laid out as one living family tree, wired together by glowing edges that trace influence. Zoom in, follow a lineage from its roots to today, and hit play on any node to actually hear it — reggae to dancehall, disco to techno, blues to metal, it's all connected.
iPHONE APP · GENERATIVE MUSIC
SynthSense
SynthSense turns your camera's view into continuously evolving generative music. The colors, light, texture, and motion in a scene play a living ambient score — digital synesthesia, running entirely on your device in real time.
iOS & ANDROID · MUSIC MIXING
PsiLoops
PsiLoops is a music-mixing app that works like a digital soundboard. Stack up to 24 melody loops in real time, drop in drum beats and one-shot effects, sweep filters, record your own vocals, then save and share the result. 1,000+ loops across genres, and always ad-free.
Games
Free browser games — nothing to install, play right here.
BROWSER GAME · FREE
Slingshot
One finger or the mouse — hold to orbit, release to fling. Space or ↑ on a keyboard.
Hold to orbit the nearest planet, let go to fling yourself along the tangent, and catch the next one before the screen leaves you behind. Grab stars on the way for points. Simple to pick up, hard to put down — every run gets a little faster.

Dub Delay · Audio Effect
DeepDub
AU · VST3 · macOS & Windows
DeepDub is a dub delay with Tape, BBD, and Digital modes, plus filtered feedback, saturation, ducking, and freeze. Use it for quick slapback or let it bloom into a whole texture.
808 Bass Synth · Instrument
EightOhEight
AU · VST3 · macOS & Windows
EightOhEight is a simple 808 bass synth built around one main knob. Keep it clean and deep, or push it into saturated, aggressive low end without digging through menus.
Lo-Fi / Glitch · Audio Effect
Computerizer
AU · VST3 · macOS & Windows
Computerizer gives you thirty digital-flavored effects in one simple plugin, and you can stack up to three at once. Choose your flavors, turn Amount, and go from light lo-fi texture to chopped-up robotic glitch.
Drum Sampler · Instrument
RatDrum
AU · VST3 · Standalone · macOS & Windows
RatDrum is a 13-pad drum sampler built for fast variation. Point it at your sample folders, shuffle one pad or the whole kit, and keep the beat moving.
Physical Modeling · Instrument
RatSound
AU · VST3 · macOS & Windows
RatSound gives you strings, brass, woodwinds, keys, plucks, mallets, and voice from physical-modeling synthesis. No huge downloads, no sample folders, full MPE expression.
Horn Section · Instrument
BrassKnuckles
AU · VST3 · Standalone · macOS & Windows
BrassKnuckles is a sampled horn section instrument — trumpet, trombone, french horn, and tuba — with an ensemble engine, falls and rises, a sub layer, and an FX chain built for horn material.
Hybrid Bell Instrument · Instrument
RatBells
AU · VST3 · Standalone · macOS & Windows
RatBells plays seven sampled bell families — tubular bells, orchestral bells, crotales, hand chimes, vibraphone, temple gongs and deep tubes — and fuses a modal bell synthesizer and an FM bell into the same voice, with a belfry engine that stacks up to six bells per note.
Hybrid Tube Instrument · Instrument
RatTubes
AU · VST3 · Standalone · macOS & Windows
RatTubes is a digital waveguide tube instrument. Tube Length, Girth, Bends, Angle, Material and End Caps shape the resonator; four exciters (Blow, Hit, Whirl and the Rat) drive it; six sampled pipe families (recorder, ocarina, didgeridoo, organ pipe, flute, whistle) sit under it; a Wormhole feeds the tube back through a pitch shifter and three Warp LFOs bend the tube to the beat.
Rhythmic Motion Effect · Audio Effect
RatMotion
AU · VST3 · Standalone · macOS & Windows
RatMotion gives anything that sustains motion locked to the host clock: four lanes (Stutter, Volume, Pan, Filter), each driven by an LFO wave or a step pattern you draw on an oscilloscope, with swing, MIDI retrigger and a harmonic tremolo mode.
Dubstep Bass Synth · Instrument
Subverter
AU · VST3 · Standalone · macOS & Windows
Subverter is a bass synth built around rhythmic filter movement. Reese oscillators, a clean sub, drawable LFO step patterns, and a mod matrix — everything aimed at wubs, throbs, and growls.
MIDI Generator · Instrument
RatMIDI
AU · VST3 · Standalone · macOS & Windows
RatMIDI generates drum grooves, melodies, harmony, and basslines from genre recipes and real music-theory rules, previews them in the plugin, then lets you drag each part out as a MIDI file — including individual drum tracks or the full kit.
Vocal Chopper · Instrument
The Choppa
AU · VST3 · macOS & Windows
The Choppa turns any vocal into a playable chop instrument. It finds the slice points for you, then your MIDI clip triggers and gates the slices in real time, and can re-pitch them.
Transition FX · Audio Effect
RatRiser
AU · VST3 · Standalone · macOS & Windows
RatRiser builds risers, downlifters, and impacts from a single automatable Rise knob — it generates the sweep and works over your track at the same time, and stays bit-transparent at rest.
Bubble / Pluck Synth · Instrument
The Bubbler
AU · VST3 · macOS & Windows
The Bubbler is a dedicated synth for the short, liquid, popping plucks all over deep dubstep and riddim. Ten macro knobs and nine characters get you from rubbery bubbles to glassy pings without programming a patch.
Flutter / Motion FX · Audio Effect
The Featherer
AU · VST3 · macOS & Windows
The Featherer makes rapid wingbeat movement — volume, resonant filter, and stereo pan all flapping together from one motion signal. Run it free, lock it to tempo, or fire it from MIDI.
Intelligent Mastering · Audio Effect
RatMaster
AU · VST3 · Standalone · macOS & Windows
RatMaster is a mastering chain for bass-heavy electronic music. Hit ANALYZE, play the drop, and it sets up EQ, bass control, glue, saturation, clipping, and limiting against a measured genre target — then hands you nine macros to change its mind.
Harmonic Exciter · Audio Effect
RatXciter
AU · VST3 · Standalone · macOS & Windows
RatXciter is a four-band harmonic exciter built for bass music. It generates new Sub, Body, Presence, and Air harmonics — never an EQ boost — so kicks and subs translate on small speakers and the top end gets air without harshness. ANALYZE sets it against the same genre profiles RatMaster uses.
Growl Bass Synth · Instrument
GrowlHound
AU · VST3 · Standalone · macOS & Windows
GrowlHound builds the five parts of a dubstep, riddim or tearout growl into one voice (an FM Throat, a vowel-shaping Mouth, Metal, Violence and tempo-locked Movement) over a separate phase-locked sub that nothing else touches.
EDM Laser Synth · Instrument
Lazy Laser
AU · VST3 · Standalone · macOS & Windows
Lazy Laser is an EDM laser instrument: play a key and it fires a laser that lands on the note, in time with the host. Seven macros (Zap, Sweep, Beam, Chirp, Echo, Spread, Ratchet) and a four-way Style switch cover pews, blasters, laser toms, harps, screech beams and risers.
Mystical Flute Instrument · Instrument
RatFlute
AU · VST3 · Standalone · macOS & Windows
RatFlute plays the epic-film desert flute: a real recorded ney, duduk and kaval and recorded alto, bass and concert flutes, blended with a modelled ney, kawala, arghul and mizmar, a maqam quantiser with real quarter tones, scoops, maqam ornaments and a vibrato that blooms, over a drone that never breathes in.
Zipper Instrument · Instrument
The Zipper
AU · VST3 · Standalone · macOS & Windows
The Zipper models a real zipper, tooth by tooth: the keyboard sets the slider speed, so the clicks turn into a pitch. Teeth, slider, pull tab, friction and the garment it is sewn into are all controls, and the neon-pastel Zipper Stage shows every tooth you hear.
Drum MIDI Generator · Instrument
DrumDNA
AU · VST3 · Standalone · macOS & Windows
DrumDNA writes arrangement-aware MIDI drum parts for EDM and rap: ten genres with five or six styles each, sections from intro to drop, 4 to 32 bars, six macros, and a Song Mode that writes the whole arrangement. Drag the MIDI onto any drum track.
Audio-Reactive Visual Synth · Audio Effect
RatVision
AU · VST3 · macOS & Windows
RatVision sits on a track, passes the audio through untouched, and turns it into tempo-locked visuals: 18 generators, 15 post effects, LFOs, a modulation matrix and eight scenes, with a fullscreen output window and a companion renderer that turns a captured performance into a movie.
Crowd Machine · Instrument
CrowdControl
AU · VST3 · Standalone · macOS & Windows
CrowdControl turns crowds into notes. Murmurs, cheers, applause and laughter excite a tuned resonator, feed a grain choir and drive a talking vocoder, all pitched to the key you play. A Crowd/Machine macro decides how much of the real crowd bleeds through, and a host-synced machine gates, stutters and tape-stops the result.
Aircraft Instrument · Instrument
AirForce
AU · VST3 · Standalone · macOS & Windows
AirForce plays aircraft. A synthesised turbine spools up when you hold a key and winds down when you let go, real aircraft recordings sit underneath it, and the Flyby sends both past you with real Doppler, distance and the swoosh of the ground echo.
Bird Instrument · Instrument
BirdMachine
AU · VST3 · Standalone · macOS & Windows
Every key from C1 to B5 is its own bird, from owls and geese at the bottom to wrens and chickadees at the top. Each bird is a real recording, a synthesised song, or both, with flocks, habitats and a dawn chorus around them.
Wild Animal Instrument · Instrument
TuskFang
AU · VST3 · Standalone · macOS & Windows
TuskFang plays wild animals. A modelled beast (larynx, vocal tract, buzzing lips) blends with recordings of real animals, so every key gives you a growl, roar, rumble, trumpet, snort or stomp, from small to monstrous, with the wild around it.
Sci-Fi SFX Instrument · Instrument
AlienFoundry
AU · VST3 · Standalone · macOS & Windows
AlienFoundry is a library of 48 playable sound effects built from real recordings of furnaces, hydraulics, rockets, spacecraft and radio from space: risers, downers, impacts, whooshes, machine events, transmissions and drones, all in tune across the keyboard.
Train Instrument · Instrument
LocoMotives
AU · VST3 · Standalone · macOS & Windows
LocoMotives turns trains into an instrument. Chord horns, steam whistles, crossing bells, brake squeals and motor whines play in tune across the keyboard, while the train itself runs underneath at the speed you set, or locked to your tempo.
Master Clarity · Audio Effect
Sunshine
AU · VST3 · Standalone · macOS & Windows
Sunshine is a master-bus clarity processor. It balances the mix toward your genre, unmasks what is buried and soothes resonances, while a loudness keeper holds the level constant, so what you hear is clarity, not volume.
Vocal Synth · Instrument
Vocalizer
AU · VST3 · macOS
Vocalizer turns typed text and MIDI notes into a sung vocal render. It is more robot hook / talkbox / autotune texture than realistic singer, and it is free.
