Modular Multi-Effect Processor
24 studio-quality effects, now with Mirage — a granular pitch-cloud you can freeze, scrub, and regenerate — plus a brickwall Master Limiter and a fresh Neon Halo look for every knob. Route, stack, and shape your sound with complete creative freedom.
Building a multi-effect chain across the 4 slots
- Load a preset — it drops into Slot 1. Click the lock icon (the slot border turns orange), then load another preset and it fills Slot 2. Repeat to stack up to 4 effects.
- Load into one slot — click a slot's box in the flow strip to select it (it gets a purple border); the next preset you browse or step to loads into that slot only.
- Random Mix (the shuffle / crossed-arrows button) randomizes every unlocked slot at once — so lock the parts you like and keep shuffling the rest.
- Drag the dashed strip under the effect animation to reorder slots, or right-click it to copy/paste an effect into another slot.
What's New
A new granular pitch-cloud (Mirage), a brickwall Master Limiter, a dedicated Texture category, and a restyled, collapsible rack.
Mirage — Granular Pitch-Cloud
A brand-new granular effect that shatters your sound into a cloud of overlapping grains you can spray, pitch, and reshape. Freeze a moment and Scrub through it, lock the cloud to a scale, slide between notes in Flatten mode, sync the grains to your tempo, or feed the cloud back into itself for evolving textures. From shimmering ambient washes to glitchy stutters — with a living grain-cloud visualiser and 12 presets to start from. Pro.
Master Limiter
A true-peak brickwall limiter on the master output as a final safety catch and loudness stage. Set a Ceiling the output will never cross, drive into it, and choose a character — Clean (transparent), Glue (a gentler, program-dependent grab), or Push (a touch of harmonic drive before limiting). Off by default and fully transparent until you switch it on, so existing projects are unaffected. Pro.
New "Texture" Category
Mirage joins Cloud Reverb and Stutterus under a dedicated Texture category — a home for granular and glitch sound-design effects, grouped together in the module picker and preset browser. The effects themselves are unchanged and all your existing presets load exactly as before.
Restyled, Collapsible Rack
Every knob has a new dimensional Neon Halo look, tinted by each effect's signature colour. And any of the four slots can now collapse to a strip — fold the ones you're not working on for a compact rack overview, then expand them back with a click. A clearer "TONE & DUCK" band and centred control groups round out the refreshed layout.
Why Spectrus?

Flexible Signal Routing
Route any slot to receive from the main input or any previous slot. Create complex effect chains with ease.
24 Studio Effects
From classic modulation to lush reverbs, tape delays to spectral processing, plus a dedicated Texture category led by the new Mirage granular pitch-cloud, Cloud Reverb's granular engine, and the Stutterus tempo-synced glitch repeater.
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.
