Xhun Zerobox

ZeroBox is an accurate analogue modeling simulation of a legendary, iconic, sequencer-driven bassline synthesizer that defined an era. In addition to a meticulous replica of both the signal path and the physics of each of the electronic components found inside the original device (oscillator, filters, envelopes, etc.), an extended set of features, improvements and circuit-bents have been added, bringing the whole synthesis engine a step ahead. Last but not least, a redesigned sequencer front-end and the inclusion of a full set of modulation, analogue saturation and multi-type distortion effects units make ZeroBox an expressive, powerful, self-contained tool for use in any electronic music scenario. That Silver Voodoo Box ZeroBox mimics not just the behaviour and physics of all the electronic components and the signal path, but also the myriad of quirks and idiosyncrasies found on the original hardware.

From the peculiarly shaped analogue oscillator’s waveforms to the iconic 4-pole diode ladder analogue filter, from the biased envelope generators to the so-called gimmick circuit, everything is faithfully preserved in ZeroBox – including the uncommon interlinks and interactions between the different components. The embedded digitally controlled sequencer is also modeled preserving the same vintage back-end logic and sub-pulse clock divisions of the original gear, while having the full benefit of a refreshed front-end with many easily accessible function improvements (triplets, shuffle, etc…).

ZeroBox can be used in conjunction with its embedded sequencer as well as with external sequencers, or as a single-oscillator monophonic solo synthesizer with a very bold sound and an incredibly deep low-end. In addition to the main bassline synthesizer, a total of six insert effects and two master effects are provided, all accessible from the single-view rack interface. It is possible to choose between a chorus unit, a flanger unit, an analogue modeled vacuum tube distortion unit, an analogue modeled transistor-based distortion unit, a digital foldback distortion unit, a creative bitcrusher unit, a digital delay unit and a resonator-based reverb unit.

Key Features:

• Physical modeling simulation: Achieved by the adoption of the Advanced Component Simulation (ACS) approach – oscillators, filters, envelopes (and more) are built preserving their original architecture, featuring all the micro-instabilities and imperfections of the analogue technology.
• Full 64-bit processing: Accuracy for every single aspect of the simulation.
• All-in-one setup: Monophonic analogue bassline synthesizer, embedded analogue sequencer, and analogue/digital insert/master effects.
• Alias-free oscillator: Provides the same capacitors’ charging/discharging responses as found on the original analogue circuits, with sawtooth and square waveforms and blending control.
• 4-pole resonant analogue filter: Modeled with the topology-preserving transform / zero-delay feedback approach.
• Analogue envelope generators: Two envelope generators preserving original analogue circuit responses.
• Analogue components age selector: Choose the virtual age of the components used inside ZeroBox affecting stability.
• Built-in circuit-bents: Found in different hardware clones and experimental ones while preserving all original functions.
• Low-frequency-oscillator (LFO): Frequency control from 0.05 Hz to 20 Hz affecting oscillator waveform blending, waveshaping and filter cutoff frequency.
• MIDI automation: Support for MIDI automation.
• 130+ factory presets: Collection covering multi-genre styles.
• Available resolutions: Multi-size GUI resolutions.
