Resonheart.

ResonHeart is the physical-modeling simulation of an experimental aerophone-based acoustic instrument with a complex modal architecture. Each voice uses a resonator block of sixteen individually triggered and tuned Helmholtz resonators, letting it mimic winds, membranes, chromatic percussion, ethnic lutes, glasses, cymbals, choirs or full string sections, as well as evolving textures. With no electronic components in its sound generation, it behaves as a real mechanical synthesizer set inside modeled room acoustics.
