Vongon Rosetones | 12-Voice Polyphonic Sympathetic Resonator & Synth Pedal

A Living Architecture of Sound

The Vongon Rosetones is a 12-voice polyphonic synth voice that breathes alongside your playing. Unlike a standard synthesizer, Rosetones functions as a sympathetic resonance engine, listening to your input and routing notes through a chromatic bank of tuned delay lines. The result is a blooming, organic texture that blurs the line between acoustic physics and digital synthesis.

Dynamic Harmonic Movement

At its core lies a 12-voice resonator bank that continuously analyzes your pitch. As you play, 12 central LEDs provide real-time visual feedback, showing exactly how your notes excite the internal engine. Whether you are seeking a subtle harmonic "halo" or an evolving wall of chords, the Rosetones responds with incredible sensitivity.

  • Intelligent Octave Shifting: Redefine your harmonies instantly. The Octave control shifts the resonator window across the keyboard range without losing track of your input pitch, allowing a bass line to trigger shimmering high-frequency inversions.
  • Modulation & Depth: Choose between Chorus for ensemble-style width or Vibrato for drifting, per-voice pitch movement.
  • Infinite Sustain: With high sensitivity and feedback settings, the Rosetones transforms into a standalone drone source, generating melodic structures from the internal noise floor even without an input signal.

Seamless Integration & Craftsmanship

Housed in a single block of CNC-routed, hand-polished walnut, the Rosetones is as much a piece of art as it is a studio tool. It supports guitar, bass, and line-level signals, with full MIDI implementation for preset management and parameter control.
