Dreadbox Hysteria

The Dreadbox Hysteria is a high-performance analog VCO Eurorack module engineered for precise pitch control and expressive sound design.

Its analog oscillator spans an extraordinary range from 16Hz up to 32,000Hz, covering the full audio spectrum and well into the ultrasonic range.

A Variable Voltage Controlled Wave Shaper enables continuous morphing of waveform character under CV control, adding dynamic harmonic content to any patch.

Advanced pitch control is provided by an integrated Voltage Controlled Quantizer, making Hysteria ideal for chromatic, microtonal, and generative compositions.

A Hard Sync Input allows the oscillator to be locked to an external clock source, producing the classic sync-sweep sounds beloved in analog synthesis.

A dedicated Pulse Output makes Hysteria equally functional as a precision clock or gate signal source within any modular system.
