1.1.1

Compatibility and preset manifest fixes

The 1.1.0 macOS installer shipped as Apple-Silicon-only with a minimum OS requirement of macOS 26, which prevented it from loading on most systems. 1.1.1 rebuilds as a universal binary (Intel + Apple Silicon) targeting macOS 11 (Big Sur) or later. This release also fixes a build-time non-determinism in the factory preset manifest that could produce duplicate Factory preset folders on some systems. Recommended for macOS and Linux users on 1.1.0. Windows users should update if they see duplicate numbered folders (e.g., Shimmer 1, Shimmer 2) in Documents\Spectrus\Factory\; otherwise optional. No audio or feature changes.

Fixes

Fixed macOS: Universal Binary — AU/VST3/CLAP now ship as Intel + Apple Silicon, so Intel Macs and Rosetta-backed hosts can load the plugin
Fixed macOS: Deployment Target — Minimum OS lowered to macOS 11 (Big Sur); the 1.1.0 build inadvertently required macOS 26 and failed to load on earlier versions
Fixed Factory preset manifest determinism — The preset manifest generator now produces identical output regardless of build host. Previously, platform-dependent path sort order and line-ending-sensitive content hashing could assign mismatched internal identifiers to duplicate-named preset files, producing duplicate numbered folders (e.g., Shimmer 1, Shimmer 2) in the Factory directory on some systems

1.1.0

Cloud Reverb joins the lineup: 10 reverbs, 22 effects

Cloud Reverb is now fully available with a new FDN reverb tail engine and 52 factory presets. Plus: a full dark/light theme system, per-slot Air & Body controls, stereo input on every effect, and dozens of quality improvements across the board.

New Features

New Cloud Reverb Factory Presets — 52 new factory presets across 6 categories (Bright, Dark, Ethereal, Organic, Spatial, Textural)
New Cloud Reverb FDN Reverb Tail — New Tail and Tail Decay controls add a lush Householder FDN reverb layer beneath the granular engine; blend between pure granular and rich, non-metallic reverb tails with independent decay time
New Per-Slot Air & Body Controls — Each effect slot now has dedicated Air (high-frequency sparkle) and Body (low-frequency warmth) knobs for per-effect tonal shaping
New Stereo Input on All Effects — Every effect now has a Stereo In knob that blends between classic mono-summed input and true stereo processing, giving you control over how stereo width feeds into each module
New Glacier Reverb Smoother Control — New knob adds extra diffusion in the feedback path for smoother, more organic reflections independent of the Diffusion knob
New Ember Reverb Stereo FDN — Stereo input is now distributed across Ember's 16-delay FDN for spatially accurate reverb; hard-panned inputs produce wide, immersive results instead of collapsing to mono
New Opt-in Update Notifications — Optional, privacy-respecting update checks (no personal data sent); enable or dismiss from the logo menu on first launch

Improvements

Improved Dark & Light Theme System — Full dark/light color theme support with four container shape presets (Sharp, Rounded, Pill, Circle); toggle via logo right-click menu; all UI elements update instantly on switch
Improved Visualizer Phosphor Persistence — All 22 visualizers now use a buffered rendering technique where previous frames fade gradually, creating ghostly motion trails unique to each effect; fade rate is audio-reactive and tuned per module
Improved Per-Module Accent Colors — Each effect's rotary slider arcs now use the module's signature accent color, matching the signal flow diagram palette
Improved Glacier Reverb Diffusion Rework — Diffusion knob is now significantly more audible; increased input diffuser delay times and connected the knob to feedback path diffusion for smoother reflections across all characters
Improved Ember Reverb Harmonic Saturation — Harmonic characters (Warm, Vintage, Bright, Dark, Lo-Fi) are now more pronounced and lively with intelligent feedback protection to prevent runaway at high decay settings
Improved Renamed Polish/Weight to Air/Body — Uses industry-standard terminology; all existing presets remain fully compatible
Improved Plate Reverb Quality — Fixed low-frequency distortion at high decay settings with in-loop soft saturation and improved low-damping filter to better match real plate physics
Improved Ember Reverb Small Rooms — Tightened small-space delays and scaled diffuser ranges by room size; small, tight rooms are now achievable at low Room Size settings

Bug Fixes

Fix Velvet Hall & Velvet Room seed presets — Random seed parameters now correctly apply when loading presets instead of carrying over from the previous preset
Fix Velvet Hall & Velvet Room seed labels — UI seed labels now update immediately on preset load
Fix Bloom factory preset seeds — 92 of 93 Bloom presets were missing seed fields, which could cause stale seed values to carry over between presets
Fix Ember Reverb damping controls — All four damping knobs (Hi Freq, High Damp, Low Freq, Low Damp) were producing no audible effect due to incorrect coefficient math; now working as intended
Fix Saturator Chebyshev mode — Rewrote the algorithm to eliminate wavefolding artifacts and raspy distortion; Shape knob now smoothly controls even/odd harmonic balance with clean results
Fix Plate Reverb reflection artifacts — Fixed persistent artifacts after large parameter sweeps by ensuring delay buffers fully rebuild on reset

1.0.0 — March 26, 2026

Initial release: 21 studio-quality effects, 4-slot modular routing, 900+ factory presets.
