Morphulus has released version 1.2.0 of Spectrus, the modular 4-slot multi-effect plug-in, headlined by Stutterus, a new tempo-synced glitch/slice repeater that brings the effect count to 23 and the Pro module count to 16. This is a free upgrade to all users.
Stutterus captures live input at every division boundary and loops the slice for the division window, optionally stacked with a manually captured or loaded sample layer for dual-source mangling. It ships with a 17-step tempo grid (8 bars down to 1/16 dotted), a per-trigger probability gate, per-slice random reverse, ±12-semitone pitch jitter, timing jitter, decay shaping, a bit-crusher, and dual envelope modes (Standard and Reverse-Swell). The sample layer adds a drag-drop waveform display with capture-from-live, scrub-region trimming, equal-power crossfade against the live layer, per-slice stereo spread, and a slow Drift LFO (Sine, Triangle, Random S&H, Saw) detuning the sample up to ±15 cents independently. Sample audio is path-referenced — no embedded audio blobs in presets.

Stutterus Tape Modes
Tape Stop / Start:
- Probability-gated tape-machine mode that replaces the normal stutter trigger with a continuous exponential rate ramp on the slice.
- The Balance dial picks Stop vs Start (left = always start, right = always stop, center = 50/50), Tape Speed sets ramp duration (1x, 2x, or 4x of the current division), and Tape Depth controls how far the rate deflects from unity.
- Flywheel physics — fast initial change, gradual coast to the floor.
Tape Wobble:
- A lighter-touch variant selected via the Tape Mode switch.
- A single asymmetric dip-and-return inside one division (quadratic fall over 25%, square-root rise over 75%) — cassette-drag physics, not a clean sine.
- Tape Speed controls dip width (1x is roughly 70% of the division, 4x about 17% and well into vibrato territory).
- Stays rhythmically locked to the grid: the rate is back at unity by the next trigger boundary.
New Across the Plug-in
Mix Lock:
- Right-click any continuous knob or Mute/Solo button and pick Lock Control to freeze it.
- Locked controls ignore preset recall, Random Mix, knob drag, scroll wheel, double-click reset, and per-module Randomize buttons.
- Locked knobs render a desaturated look with a small padlock badge.
- Covers the master strip, per-slot shared tone/filter, per-slot Mute/Solo, per-slot wet/dry mix, and per-module DSP knobs (which go dormant on module swap-out and re-engage on swap-back).
- Lock state is session-only and is never carried by presets – DAW automation and MIDI CC remain free to move locked controls.
Unified Preset Menu and Navigation:
- The Factory and User preset submenus and the next/prev navigation buttons now share a single underlying tree — menu order and navigation order can no longer drift.
- Cross-platform ordering is now deterministic instead of relying on filesystem iteration order between Windows, macOS, and Linux.
WYSIWYG User Preset Folders:
- The top level of the user preset menu is now flat-alphabetical with the folder names you gave.
- Now every folder appears as itself, with nested sub-folder structure preserved exactly as on disk.
Other Additions
Version 1.2.0 also embeds factory presets directly in the plug-in (they no longer live on disk), makes the preset Scan button refresh the user preset list to pick up newly-added presets, filters externally-deleted user presets out of both the menu and next/prev navigation, renders sub-folders above direct presets within each submenu, and fixes a logo right-click menu that could occasionally vanish on open with the first item silently selected.
