RINGS

CONTROLS

• Number of strings/structures (1, 2 or 4).
• Synthesis model (modal, sympathetic strings, string).
• Main frequency (quantized in semitones).
• Structure. With the modal and string models, controls the inharmonicity of the spectrum (which directly impacts the perceived “material”). With the sympathetic strings model, controls the intervals between strings.
• Brightness. Specifies the brightness and richness of the spectrum.
• Damping. Controls the damping rate of the sound, from 100ms to 10s.
• Position. Specifies at which point the structure is excited.

INPUTS AND OUTPUTS

• Frequency, structure, brightness, damping and position modulation CV inputs with attenuverter (-8V to +8V).
• “Strum” trigger input to indicate when a new polyphony voice needs to be allocated. Normalized to an edge detector detecting changes on the main V/Oct input, or sharp transients on the audio input. Detection threshold at 0.6V.
• 1 V/Oct frequency input (-1V to +5V).
• Resonator audio input, normalized to a filtered pulse/noise burst triggered by the “Strum” input (for stand-alone use). Modular level, up to 16Vpp.
• Two audio outputs, splitting the signal into even/odd partials in monophonic operation, or even/odd notes in polyphonic operation.
