The circuit is that of a multiple feedback bandpass filter. A short click (pulse), makes it ring with a frequency which is its natural reso-nance frequency. Oscillations die away expo-nentially and closely resemble many naturally occuring percussive or plucked sounds. The higher the Q the longer the decay time constant. H igh frequencyre sonance s re semble chimes, lower frequencies sound like claves or bongos. Several circuits, all with different tuning, driven by pulses from a rhythm generator can produce an interesting pattern of sounds.
