Reactix Raw

Great transitions shouldn't take a rack of plugins and ten automation lanes. Reactix Raw collapses the whole build into a single, fully automatable move — drop it on a loop or a breakdown, ride one knob into the drop, and release to snap clean. It's free forever, signed and notarized for macOS.

Reactix Raw is the free one-knob junior of the flagship Reactix riser engine. One knob — REACTOR — builds a full tech-house transition into the drop. Reverb, ping-pong delay, grit, a high-pass sweep and a noise wash rise together through staggered activation curves, getting bigger and more energetic, then snap clean the instant you pull back to 0. The whole build is auto-leveled, so it grows in energy without jumping in volume.

Five-module riser engine — reverb, a tempo-synced ping-pong delay, 4×-oversampled Boiler saturation, a resonant high-pass sweep from 20 Hz to 8 kHz, and an envelope-scaled noise wash, all mixed per-sample under the REACTOR macro.

Anti-aliased saturation — the saturation stage runs inside a 4× linear-phase half-band FIR oversampler for clean, alias-free drive, at a fixed quality so latency stays constant.

Level-matched macro — a 1 / (1 + drive) auto-gain on the saturated path plus the staggered activation curves keep volume steady across the sweep, so the riser grows in energy without jumping in loudness.

Frequency-dependent stereo width — a 300 Hz Linkwitz-Riley crossover keeps the low band mono-safe while widening the highs, blended in by the macro so 0% stays bit-clean.

Output safety — a 20 Hz DC blocker removes any offset after saturation, a −0.1 dB internal clipper bounds the level, and non-finite samples are zeroed, so no knob position can drive a runaway or clipped output.
