Modular Add-On: Mutable Instruments Rings Resonator Module

Rings offers three models. The modal resonator emulates plates, strings, membranes and tubes, placing resonant frequencies at modes set by a material's size, shape and structure.

The sympathetic strings model produces droning and overtone textures, similar to the sympathetic resonance of instruments such as the sitar. The modulated and inharmonic string model extends Karplus-Strong synthesis, which uses a short, high-feedback delay to produce a pitched tone like a plucked or struck string.

You can excite the resonators with the built-in noise pulse or with an external audio signal, so any input can drive the resonant models. Timbral controls shape the resulting sound.

Rings provides up to four voices of polyphony. Each trigger generates a new virtual string, even while previous notes still ring, which allows strummed chords.
