REFLEXION

Light reflecting between surfaces.

REFLEXION is built around an eight-channel modulated Feedback Delay Network with an orthogonal Hadamard mixing matrix — the same architectural family as Lexicon's 480, Bricasti's M7 and Valhalla's algorithmic engines. A four-stage nested all-pass diffuser handles onset, a twelve-tap stereo cluster places early reflections inside the modelled space, and per-line modulation smears the comb-filter resonances that haunt cheaper reverbs into a tail that breathes.

Inside the engine

Architecture that competes with the giants.

Every algorithm is engineered from first principles in C++ and JUCE. No shortcuts, no off-the-shelf reverbs hidden behind a new face.

01

8-channel modulated FDN

Orthogonal Hadamard recirculation: maximally dense, never metallic. Per-line LFO modulation between 0.5–1.2 Hz smears comb resonances into life.

02

Nested all-pass diffusion

Four Gardner / Dattorro-style nested all-passes spread every transient into a cloud before it enters the late tail — the trick that makes vocals and drums feel expensive.

03

Three room shapes

Hall, Plate and Chamber early-reflection patterns sit on top of the same late engine, swapping the geometric character of the modelled space in one click.

04

Studio-grade tone shaping

Pre-delay 0–200 ms, low-cut 20–500 Hz, high-cut 2–20 kHz, low + high shelves, M/S width control. Everything you need to sit the reverb in any mix.

The Concept

Light reflecting between surfaces, translated into sound.

A premium algorithmic reverb engineered around an 8-channel modulated FDN — the same architectural family as the most respected algorithmic engines in audio.
