Modular Multi-Effect Processor
22 studio-quality effects, now with granular Cloud Reverb, dark/light themes, and per-slot tone control. Route, stack, and shape your sound with complete creative freedom.
What's New
A major update: new reverb engine, new look, and finer-grained control over every slot.
Cloud Reverb — Granular
A lush granular reverb. Spawn clouds of audio grains with variable size, density, pitch, and freeze, then blend in an optional FDN tail for a rich, non-metallic decay. 52 factory presets across Bright, Dark, Ethereal, Organic, Spatial, and Textural.
Dark & Light Themes
A polished dark theme and a clean light theme, each with four container shape presets: Sharp, Rounded, Pill, and Circle. Every control, meter, and visualizer updates instantly.
Phosphor Visualizers
All 22 visualizers now render with phosphor-persistence: previous frames fade like analog hardware, leaving ghostly motion trails tuned to each effect's character.
Finer-Grained Control
Per-slot Air and Body knobs, plus a Stereo In control on every effect that blends between classic mono-sum processing and full stereo.
Why Spectrus?
4-Slot Modular Architecture
Chain up to 4 effects in series or parallel. Each slot has independent level control and wet/dry mixing for precise sound design.
Flexible Signal Routing
Route any slot to receive from the main input or any previous slot. Create complex effect chains with ease.
22 Studio Effects
From classic modulation to lush reverbs, tape delays to spectral processing, including 10 reverbs led by the new Cloud Reverb granular engine.
Dark & Light Themes
Switch between a polished dark theme and a bright light theme to match your DAW or your mood. Every control, meter, and visualizer adapts instantly.
Per-Slot Tone & Stereo
Dedicated Air (sparkle) and Body (warmth) knobs on every slot, plus a new Stereo In control on every effect that continuously blends between classic mono-sum processing and full stereo. No more choosing between vintage character and width.
916 Factory presets
Save and recall your favorite configurations. Organize presets into folders. Lock slots to preserve settings across preset changes.
Low CPU Usage
Optimized DSP code means you can run multiple instances without bogging down your session.
Try All 22 Effects Free
Demo mode gives you full access to every effect (including all 15 Pro effects) so you can explore everything before you buy. A gentle periodic fade is the only reminder.
Slot Lock, Drag & Drop, Copy & Paste
Lock any slot to preserve its settings while browsing presets. Drag slots to reorder them, or right-click to copy and paste an effect configuration between slots.
