Xhun Audio releases ZeroBox Analogue Modeled Bassline Synthesizer with Introductory Offer

Xhun Audio has released ZeroBox, an analogue modeling simulation of the iconic TB-303 Bass Line synthesizer released in the 1980s.

The basic approach / idea behind ZeroBox is to meticulously preserve the physics and behavior of the analogue circuit components, topology and quirks as found in the original 1980s hardware, while at the same time expanding such device's possibilities by the introduction of a series of "mods" and "circuit bents" as found on many so-called "DIY projects" from the 1990s.

ZeroBox (regular price: 89.00 Euro / 99.00 USD) is available now for 39.00 Euro / 49.00 USD by joining the time-limited, 50% off special introductory offer. This offer is available from the Xhun Audio Shop as well as from selected 3rd party Dealers.

ZeroBox is available as a VST, VST3, AU plugin for Windows and macOS (Intel CPU). Although running the software on M1 macOS (Apple CPU) is possible using Rosetta 2, Xhun Audio strongly recommends to download and try the demo version before buying.

Features list:

• Physical modeling simulation of real analogue hardware, achieved by the adoption of the Advanced Component Simulation (ACS) approach - oscillators, filters, envelopes (, ...) 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.
• An all-in-one complete setup: monophonic analogue bassline synthesizer + embedded analogue sequencer + analogue and digital insert/master effects.
• Full preservation of all quirks found on the original device:
  • The iconic gimmick circuit and its signal paths.
  • The analogue filter limited self-oscillation.
  • The peculiar behaviour of the accent and slide functions.
  • The internal signal polarity inversion.
• An aliasing-free analogue modeled oscillator proving the same capacitors' charging/discharging responses as found on the original analogue circuits, featuring sawtooth and square waveforms with blending (morphing) control.
• A separate control for the oscillator waveshaping (from naive to analogue supersaw / pulse width modulation).
• An iconic 4-pole resonant, analogue low pass diode ladder filter (modeled by the adoption of the topology-preserving transform / zero-delay feedback approach) proving all the original quirks, non-linearities, frequency responses (also at extreme modulation scenarios), analogue clipping.
• Two analogue envelope generators (MEG / VEG) proving the same capacitors' charging/discharging responses as found on the original analogue circuits.
• Analogue components age selector. Choose the virtual age of the components used inside ZeroBox and, as a consequence, its resulting overall instability.
• An extended operative range (compared to the original) for several knobs and internal components.
• Built-in circuit-bents as found in different hardware clones and also never seen before, experimental ones (while 100% preserving all the original functions)
  • An exclusive low-frequency-oscillator (LFO) with frequency (from 0.05 Hz up to 20 Hz) and destination amount controls, affecting the oscillator waveform blending, waveshaping and filter cutoff frequency.
  • Adjustable highpass filter cutoff frequency.
  • Adjustable filter envelope (MEG) minimum decay time.
  • Adjustable slide time control.
  • A VCA envelope (VEG) smoother control.
  • Polarity inverter control, useful to achieve different sound flavours when using an asymmetric (biased) distortion unit.
• Three ways of control, for both studio and / or live scenarios:
  • Sequencer Off: individual notes are MIDI triggered directly by the DAW.
  • Sequencer (Pitched): the internal sequencer (8 scenes / patterns per preset) is MIDI triggered and tuned.
  • Sequencer (KeyTrig): each of the 8 sequencer scenes / patterns (per preset) are assigned to different MIDI keys.
• A multi-mode (PTC / KTG) embedded digitally controlled clock generator and sequencer, featuring the same internal pulse timing and behaviour of the original one, with:
  • Mode selector (normal / triplet).
  • Beat pulse divider selector.
  • Tempo / external controls.
  • Swing amount control.
  • Step gate control.
  • Step pitch control.
  • Step octave selector.
  • Step slide control.
  • Step accent control.
  • Steps number (from 1 up to 16) selector.
• A multi-scene loader engine with 8 scenes per preset.
• Including an insert effect slot with the possibility to choose:
  • CHOR-S unit (rack), an expressive stereo chorus effect.
  • FLANG-R unit (rack), an expressive stereo flanger effect.
  • X-TREME unit (rack), an accurately modeled, ground-shaking tube distortion effect.
  • SOLIDA unit (rack), an accurately modeled, rock-solid transistor distortion effect.
  • PHEEBEE unit (rack), an expressive digital foldback distortion effect.
  • CRUSH-R unit (rack), a creative digital bitcrusher effect.
• Including a master effect slot with the possibility to choose:
  • D-LAY unit (rack), a tempo-synced stereo delay effect.
  • REEVERB unit (rack), a resonator-based electronic reverb effect.
• Including 130+ ready-to-use factory presets collection covering multi-genre styles.
• Multi-color synth panel (silver grey or acid yellow).
• MIDI automation.
• Support for sample rates from 44.1 kHz up to 192 kHz.
• Available in multi-size GUI resolutions.
