nRINGS

NanoRings was developed by Jim Matheson as a smaller version of original
Mutable Instruments Rings with identical functionality.

Three resonator models
Modal resonator, as used in Elements.
Sympathetic strings, modelled by a network of comb filters.
String with non-linearity/dispersion (comb filter with multimode filter and non-linearities in the loop).
All resonator models can be used polyphonically, with 1, 2 or 4 polyphony voices.

Voltage-controlled resonator
Each model provides a unified set of parameters, all voltage controlled, with an attenuverter:

Structure. With the modal and non-linear 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.

Manufactured by Twangmodular.
