Reactix is a macro-controlled transition engine. Five effect modules — reverb, delay, saturation, HP filter sweep and noise wash — sit behind a single Master Reactor knob. At 0% the signal is completely clean. Push it toward 100% and each module joins on a staggered curve, building a smooth rolling transition. Release the automation for the drop and everything snaps clean. One automation lane gives you the entire build.The Five Modules• Diffusion — high-decay reverb, up to 80% wet• Feedback — tempo-synced 1/8 ping-pong delay• The Burn — saturation in Boiler (warm tube grit), Volt (bitcrush + bright delay) or Vacuum (dark muffled tension) modes• Filter — dual-pole resonant HP sweep from 20 Hz to 8 kHz• The Wash — sidechain-envelope-following noiseGhost-Fill Sidechain• Automatic transient detection ducks the wet signal up to 12 dB per hit• Ghost Amount sets duck depth, Ghost Release from 50 to 500 ms• Targets only the FX wash — the kick stays present while the tail pumps behind itStability• Stable — everything tempo-locked and professional• Unstable — LFO modulates delay time and reverb pre-delay for analog-degradation characterPerformance• MELTDOWN — hold to force all modules to 100% with self-oscillating delay and a resonant LP sweep; release for instant silence• COUNTDOWN — auto-ramps the reactor 0 to 100% over 4, 8 or 16 bars synced to your host tempo• Fusion Streak tracks consecutive smooth builds• Reactor Seed encodes settings as a shareable string12 factory presets · RND randomize · A/B compare · .preset save/loadAU, VST3 and Standalone — Universal Binary (Apple Silicon + Intel), code-signed and notarized by Apple so it installs cleanly on macOS.Requires macOS 15.0 or later.
