★ Self-contained melodic resonator
Sequencer into V/OCT only — Resonate generates its own exciter on each note change.
Walkthrough
  1. Set Resonator Type to Modal.
  2. Set Polyphony to 1 voice.
  3. DAMPING ~1 o'clock, BRIGHTNESS ~noon, STRUCTURE ~noon, POSITION ~noon.
  4. Leave STRUM and IN unpatched — the internal exciter fires on V/OCT step changes.
  5. Patch sequencer pitch CV → V/OCT.
  6. Patch ODD → mixer input.
Signal out ODD — mono modal-resonator audio (±5V range) with internal mallet exciter.
Listen for A plucked metallic/wooden bar that retriggers on every new note from the sequencer. No gate cable needed.

★ Drum hits as exciter
Drum transients feed IN so Resonate becomes a pitched resonant body tuned by V/OCT.
Walkthrough
  1. Set Resonator Type to Modal.
  2. DAMPING ~10 o'clock (short decay so resonance tails don't smear the groove).
  3. BRIGHTNESS ~1 o'clock, STRUCTURE ~11 o'clock.
  4. Patch a drum / click source → IN. (Patching IN disables the internal exciter.)
  5. Patch sequencer pitch CV → V/OCT — each hit rings at the sequenced note.
  6. Leave STRUM unpatched — IN transients auto-trigger new voices.
  7. Patch ODD → mixer L, EVEN → mixer R for stereo.
Signal out ODD / EVEN — resonated drum audio, pitched by V/OCT, stereo-complementary.
Listen for Drums turn into tuned tom/bell hybrids that follow your melody. Each transient excites the modal bank at the current pitch.

★ Polyphonic chords
4-voice polyphony with a fast pitch sequence strums chords from the internal exciter.
Walkthrough
  1. Set Resonator Type to Sympathetic strings (for piano/harp character) or Modal.
  2. Set Polyphony to 4 voices.
  3. DAMPING ~2 o'clock, BRIGHTNESS ~2 o'clock, STRUCTURE ~1 o'clock.
  4. Patch an arpeggiator / rapid pitch sequencer → V/OCT. Each step freezes the previous voice and fires a new one.
  5. Leave STRUM unpatched (V/OCT step detector does the strumming). IN unpatched so internal exciter fires.
  6. Patch ODD → mixer L, EVEN → mixer R for stereo chord spread.
Signal out ODD / EVEN — up to 4 overlapping voices split into odd/even strings. Decay shortens as voices stack.
Listen for Plucked chords bloom as each sequencer step adds a new voice on top of the decaying previous one.

Granular exciter chamber
uBurst granular cloud drives IN as a continuous bowing-like exciter for sympathetic strings.
Walkthrough
  1. Set Resonator Type to Sympathetic strings.
  2. STRUCTURE past noon (wider detuning between strings), DAMPING high (long sustain).
  3. BRIGHTNESS ~1 o'clock, POSITION ~noon.
  4. Patch uBurst (Left Out) → Resonate IN — the grain cloud replaces the internal mallet.
  5. Patch a slow LFO → uBurst Position CV for small grain motion.
  6. Patch a quantized sequencer → Resonate V/OCT.
  7. Patch ODD → mixer L, EVEN → mixer R.
Signal out ODD / EVEN — sympathetic strings continuously excited by granular cloud, stereo.
Listen for A bowed sitar-like sustain where grains keep exciting the string bank. Evolving overtones as STRUCTURE detunes.

DV tail as sympathetic resonance
Desmodus Versio reverb tail excites IN while density CV shapes Damping — reverb becomes pitched string resonance.
Walkthrough
  1. Set Resonator Type to Sympathetic strings.
  2. STRUCTURE ~10 o'clock, DAMPING high as a starting point, BRIGHTNESS ~noon.
  3. Patch Desmodus Versio (Out L) → Resonate IN — the wet tail drives the strings.
  4. Patch a density-envelope CV from uBurst → Resonate Damping CV; set the attenuverter to taste.
  5. Patch a slow quantized sequencer → Resonate V/OCT.
  6. Leave STRUM unpatched.
  7. Patch ODD → mixer L, EVEN → mixer R.
Signal out ODD / EVEN — reverb tail re-pitched as sympathetic strings, Damping CV'd in real time.
Listen for A lush reverb that slowly blooms into pitched sitar-like harmonics, the decay breathing with the density envelope.

Resonate + uBurst infinite drone loop
Closed feedback between Resonate and uBurst — envelope-follower self-plucks on cloud peaks for an infinite drone.
Walkthrough
  1. Set Resonator Type to Modal, DAMPING high, BRIGHTNESS ~2 o'clock.
  2. Patch a slow sequencer → Resonate V/OCT.
  3. Patch Resonate ODD → uBurst IN L.
  4. Patch uBurst Out L → envelope follower → Resonate STRUM (peaks re-pluck Resonate).
  5. Patch uBurst Out R → attenuator (start fully CCW) → uBurst Freeze CV for self-latching texture.
  6. Raise the feedback attenuator slowly — too loud and the loop runs away.
  7. Patch uBurst Out R → main output.
Signal out uBurst Out R — evolving drone cloud continuously re-excited by Resonate peaks.
Listen for An eternal metallic cloud that feeds itself: each grain peak re-strikes Resonate, whose output re-feeds uBurst. Sequencer pitch nudges the drone's center.

Behaviors

Modal Resonator Resonator type → modal

Simulates resonance of vibrating structures (bars, plates, strings) using a bank of band-pass filters. Structure sets frequency ratio between partials.

Sympathetic Strings Resonator type → sympathetic

Simulates strings that vibrate in response to other strings using comb filters. Structure sets tuning ratio between the strings for extra overtones.

Non-linear/Inharmonic String Resonator type → non-linear

Extended Karplus-Strong with non-linearities and dispersion all-pass filter. Structure sets degree of inharmonicity.

Internal Excitation IN unpatched

When IN is unpatched, the module generates its own excitation signal (LP-filtered pulse or noise burst depending on resonator type) on each note change or STRUM.

Polyphonic Strumming STRUM input / V/OCT step change

In 2 or 4-voice polyphony, successive notes overlap without cutting each other's tails. Rapidly send different pitches to create chords by strumming.

Controls

Global Polyphony Setting Selects monophonic, duophonic, or quadraphonic operation. More voices overlap without cutting tails.
1, 2, or 4 voice polyphony
Global Resonator Type Selects resonator model: modal (bars/plates), sympathetic strings (comb filters), or non-linear/inharmonic string (extended Karplus-Strong).
Modal · Sympathetic strings · Non-linear string
Global Frequency (Coarse) Coarse frequency control. Quantized in semitones when a cable is patched to the V/OCT input.
Quantized in semitones when V/OCT patched
Global Structure Harmonic structure. Frequency ratio between partials (modal), detuning of strings (sympathetic), or non-linearity/inharmonicity (string).
Behavior varies by resonator type
Global Brightness Adjusts level of higher harmonics. Acts simultaneously on LPF of exciter (closed at 8 o'clock) and damping filter on higher modes.
8 o'clock=closed · noon=fully open LPF
Global Damping Controls the decay time of the sound.
Short to long decay
Global Position Excitation position on the string/surface. Similar to PWM on a square oscillator or comb-filtering of a phaser.

CV Inputs Attenuverters (4x) Attenuverters for the CV inputs (Frequency, Structure, Brightness, Position/Damping).
