Patching Panda – Hatz

This is the V3 Version of Hatz

Hi-hats are typically rich in complex, inharmonic frequencies that create a metallic, shimmering sound. Hi-hats rely heavily on noise components to create the "sizzle" effect. While analog circuits can generate white or colored noise using transistors or diodes, it's difficult to get the noise characteristics just right for hi-hats. Designing a noise source that consistently produces the right quality and amount of noise can require fine-tuning and careful component selection. Hi-hats need very fast attack and controlled decay to emulate the sharpness of a real cymbal. Achieving precise control over these fast transients is challenging in analog circuits.

Hatz v3 is an analog circuit that includes 2 types of noise: "Metals" generates stable, high-frequency square wave oscillations that are essential for the metallic, bright sound characteristic of hi-hats. "Texture generates a unique, digital form of noise that has a slightly "stepped" quality, adding a texture that's not as smooth as white noise, but has a desirable grain.

Independent envelopes for precise transient shaping and a bandpass filter for frequency control contribute to a complex, high-quality hi-hat sound. This design approach provides flexibility, realism, and sonic richness that elevates the hi-hat beyond basic analog percussion.
