Lovingly adapted for Eurorack, the HATS808 brings the sizzling and lively hi-hats of the TR-808 to a tremendously small format. Just like the original, this module uses six square waves processed through band pass filters. Unlike the original, the HATS808 adds resonance with voltage control to the band pass circuit for additional tonal variation. Beyond being a simple duplicate of the circuit, Tiptop added functionality from years of 808 implementation. Primary to this is the extended range of the Level knob, providing gain and distortion sufficient to add harmonics to the HATS808 signal, a technique traditionally realized through outboard pre-amps and distortion circuits. For ease of operation, Tiptop designed a dual pulse-shaper circuit on the input, so that any trigger, gate, pulse, or clock will perform correctly with the HATS808, regardless of power differences from the source.
