Harmonic Dissector

Dual parallel resonant filters with slewed slots, clocked stepping, stereo motion, and harmonic edge.

What it is

Harmonic Dissector is a dual-section, parallel resonant filter effect for controllable harmonic shaping and movement. Each section has independent frequency, resonance behavior, drive, level, modulation, and pan, and the v1.2 slot system lets those settings move between four stored states.

The two filter sections run in parallel, so each side can follow its own frequency, bandwidth, drive, level, and pan shape. The four slots can be randomized, copied, pasted, slewed, stepped by internal clock, or stepped by host sync, which turns the plugin into a compact motion tool as much as a filter.

Use it for resonant stereo movement, tremolo and auto-pan shapes, stepping or sweeping filter patterns, narrow-band character on synths and bass, and more animated distortion when the LFOs are pushed into audio-rate territory.

Highlights

Dual parallel resonant lanes

Build two independent spectral motion paths with dedicated frequency, bandwidth, drive, level, and pan controls.

Four slewed slots

Store four states and move between them with slew, internal clock, or host sync.

Randomize, copy, and refine

Randomize section settings, copy and paste slots, then narrow in on useful motion without rebuilding the patch.

How producers use it

  • Tremolo and auto-pan movement from level and pan slots
  • Stepped or sweeping resonant filter patterns
  • Animated harmonic focus for synths, Rhodes, bass, and loops

Fit and focus

Great fit for:

  • resonant filtering with motion
  • compact slot-based modulation
  • parallel signal design
  • filter effects that like to move

Questions people ask

What is Harmonic Dissector?

It is a dual-section resonant filter effect with parallel topology, independent controls for each section, and four slots for moving between stored states.

How does the slot system work?

Each slot stores a filter state. You can switch manually, step with internal or host clock, add slew between states, randomize slots, and copy or paste them when you want the two sides to line up.

Who is it for?

Producers who want animated spectral control, resonant movement, and quick filter patterns without building complex routing externally.

What does it do to sound?

It can tighten focus, create moving formant-like emphasis, add stereo pan and level motion, and introduce driven resonant character that evolves in time.

Compatibility

macOS 10.15+, Windows 10/11
macOS: AU/VST3, Windows: VST3

These plugins use detailed real-time processing and are happiest on reasonably recent CPUs, especially when several instances are running at once.
