The Dreadbox Hysteria is an analog oscillator with built-in quantizer that is part of the Chromatic Modules series. Thanks to the internal quantizer, the oscillator is always precisely tuned and can thus be set with concrete note reference. If the quantizer is deactivated, the frequency range can be freely determined without intervals. Seven variable waveforms are available, these can be selected and modulated with CV. With the FM input, Hard Sync and the Pulse output for synchronizing other oscillators, the Hysteria VCO is supplemented by exciting features.
