Rosetones creates a polyphonic synth voice that follows your playing. it listens to your notes and routes them through sympathetic resonators, creating blooming harmonic textures and evolving chords
At the center of Rosetones is a 12-voice chromatic resonator bank that continuously analyzes the input signal and routes detected pitches into tuned delay lines. each pitch class excites a resonator that can sustain, swell, and interact with feedback to create dynamic harmonic movement. the twelve central LEDs display the signal level of each resonator in real time, showing how incoming notes are exciting the 12-voice bank. the result is part synthesizer, part acoustic resonance engine
The octave control shifts the active 12-note window across the keyboard range, redefining where the resonators are voiced while pitch detection remains unchanged. play a basic triad and adjust the octave control to re-voice the same notes into new inversions. a low bass line can drive higher voiced resonators, transforming weight into shimmer and contrast
Modulation adds motion and depth to the resonator bank. CHORUS introduces subtle multi-voice detuning for ensemble-style width, while VIBRATO applies drifting pitch movement per synth voice. the sens and feedback controls shape how strongly notes excite the resonators and how long they sustain, ranging from short percussive resonance to evolving harmonic bloom
Any equal-tempered instrument such as guitar, bass, or synthesizer can drive the resonator bank with natural tracking response. MIDI note messages allow precise pitch articulation layered over input audio, enabling harmonies that follow the timing and phrasing of your performance. percussive sources can reveal melodic structure, while sustained lines expand into harmonic space
Rosetones can also function as a standalone sound source. with no input signal, higher sens and feedback settings allow the internal noise floor to excite and 4sustain the resonators, producing a unique drone voice shaped by octave, tone, and modulation
Additional features include selectable gain and bypass modes, full MIDI control of every faceplate function, and onboard preset storage. powered by a standard 9-volt center-negative supply, Rosetones integrates seamlessly into pedalboards and studio setups
