Vongon Rosetones

The Vongon Rosetones is a polyphonic resonant string synthesiser that transforms your playing into evolving harmonic textures. By tracking incoming notes and routing them through a bank of sympathetic resonators, it creates blooming chords, sustained tones and shifting layers of sound that respond to the music you play.

At the heart of Rosetones is a 12 voice chromatic resonator bank that continuously analyses the incoming signal and directs detected pitches into tuned delay lines. Each pitch class excites its own resonator, which can sustain, swell and interact with feedback to create complex, evolving harmonics. The result is an instrument that can add depth and movement to simple guitar parts, or turn dense chord voicings into rich, almost orchestral soundscapes.

Rosetones is designed to work with both instrument and line level signals, making it equally at home alongside guitar pedals, synthesisers and studio equipment. With a choice of analogue buffered or DSP bypass, a soft touch footswitch and MIDI connectivity, it offers a practical way to explore more experimental sounds in a live or recording setup.
