Reactix

Reactix is a single-knob transition engine for macOS. One Master Reactor macro drives a whole beat-synced multi-FX chain — reverb, delay, saturation, a resonant high-pass sweep, and an input-following noise wash — taking a track from completely clean at 0% to a full wall of wash at 100%. Three Reactor Modes set the character (Boiler warm tube grit, Volt bright bitcrush, Vacuum dark low-pass tension); Transient Preserve uses Linkwitz-Riley crossovers to keep your punch under heavy settings; and Ghost-Fill sidechains the wet FX to your input so kicks and snares stay present. Stable mode locks builds to tempo, Unstable adds analog-style wobble to the tails. Ride one knob live or automate it for instant risers, build-ups and breakdowns. 12 factory presets.

Formats: AU, VST3, and Standalone — Universal Binary (Apple Silicon + Intel), code-signed and notarized by Apple, so it installs cleanly on macOS.
