DarkLxPro

DarkLXPro — Premium Algorithmic Reverb

A Lexicon-class algorithmic reverb built around a dense, modern 16-line Feedback Delay Network. Designed to deliver the lush, sparkling, “expensive” reverb sound of the most legendary studio hardware — without the rack space. From tight ambient rooms to massive 12-second halls, DarkLXPro is the reverb you reach for when nothing else will do.

16-Line FDN engine:

• 16 delay lines (double the typical 8) — much denser, smoother tail
• Hadamard 16×16 mixing matrix via 4-stage butterfly decomposition — maximum density at minimum CPU cost
• 16 coprime prime delays — mutually coprime values prevent flutter echoes and resonant artifacts
• Stereo line split: lines 0–7 → Left, lines 8–15 → Right — true stereo dispersion, not pseudo-stereo
• Stereo input diffusion: 2 × 4 allpass stages with offset delays
• Stereo cloud diffusion: 2 × 4 nested allpass stages — Lexicon-style dense reflection cloud
• Smooth ER → FDN crossfade — no audible split between early reflections and late field
• Frequency-dependent stereo width with constant-power mix law

Controls:

• Room Size (0.5–2.0) — virtual room dimensions
• Decay (0.1–12 s) — RT60 reverberation time
• Pre-Delay (0–500 ms) — separation between dry and reverb
• Damping (0–100%) — global tail darkening
• Low Damp (0–100%) — independent low-frequency damping in the feedback path
• High Cut (1 kHz – 20 kHz) — air control
• Low Cut (20 Hz – 1 kHz) — mud control
• ER Level (0–100%) — early reflections amount
• Mod Depth (0–100%) — internal modulation for natural tail movement (prevents metallic ringing)
• Width (0–200%) — stereo spread
• Ducking (0–100%) — automatic reverb attenuation while the dry signal is loud (keeps mixes clean)
• Mix (0–100%) dry/wet
