RESONATOR

O Resonator v1.1.0 is a rotating seven-ring string body for sustained resonance, motion coupling, and external audio transformation. The current build introduces a three-page workflow for performance, physical motion, and final output shaping while preserving the original research-demo design.

Download v1.1.0 Control Guide

Research demo v1.1.0. Windows and Linux builds are available as a standalone host application, VST3 effect plug-in, and VST3 instrument plug-in.

Version 1.1.0

Download

Get the current Windows and Linux demo builds from the official GitHub v1.1.0 release page. The release includes standalone host, VST3 effect, and VST3 instrument packages.

Three Pages

The interface is now organised into MAIN for performance, COUPLING for disk and string motion, and OUTPUT for final EQ, protection, recording, and meters.

Final Result Update

Version 1.1.0 adds Motion Coupling, Output Guard, Final EQ, Record Output, DAW-style recording waveform, compact dropdowns, and final layout wiring cleanup.

Features

What Is New In v1.1.0

Seven-Ring Body

Seven tuned circular string paths remain the harmonic core. Open rings contribute to one shared resonant body; closed rings stay silent or nearly silent.

Motion Coupling

The new COUPLING page lets the disk behave as a locked body, slipping body, or orbital field with controls for slip, radius bias, friction, surface, Doppler, and body field.

Three-Page Interface

MAIN handles performance and ring activation. COUPLING shapes physical motion. OUTPUT finishes, protects, monitors, and records the sound.

Final Output Tools

The OUTPUT page adds Final EQ, Output Guard, final meters, signal-flow status, and a DAW-style Record Output waveform lane.

Instrument And Processor

Use it as a standalone host for sustained rotating resonance or as a VST3 effect to transform vocals, guitar, synth, drums, field recordings, and noise.

Blooming Resonance

The sound blooms instead of striking. Active rings rise into motion, sustain, decay, slip, and final output shaping as one connected body.


Sound Model

What Makes It Different

RINGS
HARMONIC BODY

The seven rings define the instrument’s tonal architecture. Choosing which rings are open changes the harmonic centre and the weight of the body, from low dark drones to brighter upper-ring shimmer and stacked resonant harmonies.

MOTION
SHARED FLYWHEEL

Movement comes from a shared flywheel rather than an LFO grid, step sequencer, or arpeggiator. The flywheel continuously shapes active rings through pressure, damping, brightness, inertia, and phase, producing rotation, bloom, drift, and energy.

INPUT
INSTRUMENT OR EFFECT

O Resonator can create its own sustained tone or process incoming sound. In effect use, a voice, synth, guitar, drum loop, or field recording can be revoiced through the selected circular string paths and animated by the same rotating body.

BODY
CONTINUOUS RESONANCE

The active strings are not played one after another. They combine as a sustained resonant body, allowing the sound to feel harmonic and textural at the same time: stable enough to hold a tone, flexible enough to evolve, and physical enough to respond like an object in motion.


Workflow

Three Connected Pages

1
MAIN

Open rings, assign notes, shape flywheel movement, monitor the resonator bank, and perform the core seven-ring instrument or effect.

2
COUPLING

Shape disk-to-string behaviour with coupling mode, slip, friction, radius bias, Doppler, trajectory, stereo orbit, phase spread, and centre body field.

3
OUTPUT

Finish the sound with Final EQ and Output Guard, watch final meters, check signal-flow state, and record the output in the standalone application.


Control Guide

Main Control Areas

GLOBAL
ENGINE AND CLOCK

Engine On controls whether O Resonator produces output. Disk On controls rotation and motion physics. Clock Host locks the disk timing to the DAW when available. Speed, Time Mapping, Reset, Phase, Direction, Evolution, Rise, Flywheel, Inertia, Mod Depth, and Period shape the shared motion field.

STRINGS
RING BEHAVIOUR

String activation buttons open or close the seven ring paths. Harmony chooses ring groupings. Note assignment retunes active paths. Pressure, Sustain Feed, String Sustain, Damping, Rub Energy, Bend, Harmonics, Bright Move, Motion Drift, Texture, Body Move, Body Grit, and Input Response shape colour, tension, brightness, sustain, and physical feel.

COUPLING
SLIP AND BODY FIELD

Coupling Mode chooses Locked, Slip, or Orbital behaviour. String Coupling determines how strongly strings follow the disk. Slip Amount, Radius Bias, Friction, Surface, Pressure Link, Noise Texture, Doppler, Trajectory, Stereo Orbit, Phase Spread, Body Field, Field Strength, Field Damping, and Radiance shape the physical motion layer.

OUTPUT
EQ GUARD RECORD

Final EQ provides Low Cut, Low Gain, Mid Freq, Mid Gain, Mid Q, High Gain, and High Cut. Output Guard adds Ceiling, Drive, Release, Isolation, and gain-reduction feedback. Record Output records the final heard output and displays a DAW-style waveform lane.


Quick Start

Start With The v1.1.0 Workflow

1
MAIN

Activate D2 and A3, turn Engine On and Disk On, then raise Sustain Feed and Pressure until the resonant body blooms.

2
COUPLING

Choose Locked for clean motion or Slip for disk-against-string friction. Use Radius Bias, Doppler, and Body Field to shape movement and physical depth.

3
OUTPUT

Use Final EQ for tone, Output Guard for protection and isolation, then use Record Output in standalone mode to capture the final result.


FAQ

Common Questions

START
GETTING SOUND

Turn Engine On, activate at least one ring, start Disk motion, then raise Sustain Feed, Pressure, Mix, and Master until the resonant body blooms. In effect mode, also confirm that audio is entering the plug-in and raise Input Gain.

DISK
MOTION ONLY

Disk On controls rotation and motion physics. Disk Off stops slip motion, friction motion, Doppler motion, and rotation-dependent movement. Engine On controls whether O Resonator produces output.

RECORD
OUTPUT CAPTURE

Record Output is for the standalone build. It captures the final heard output after the resonator, body, Final EQ, Output Guard, and Master stages, and displays a real-time waveform lane while recording.

MIDI
ACTIVE RINGS ONLY

MIDI retunes or fingers active strings. It should not make closed rings audible, trigger hidden notes, or create an arpeggio.
