Karplus-Strong voice+resonator

Reso Legio is a physical-modeling voice based on a Karplus-Strong algorithm fed into a parallel bandpass-bank body resonator. The pluck excitation also feeds the body resonator to emulate the sound of picked instruments. External sounds can also be fed into the stereo body resonator. Add in a chorus and three body models and you've got a physical-modeling playground in just 6 HP!
