    Digital Products

    Digital Products are delivered electronically either via your order status page, or via email.

    No physical product will be shipped to you!

    In most cases, the product you purchase from us is a serial number/license code/activation code to register the product with the manufacturer and download directly from them. This ensures you receive the latest version of products, and the best support when necessary.

    After purchase, your license code and relevant links will appear on your order status page, or they will be sent to you by email.

Education Proof

Products with education pricing are for students & teachers only. To prove your education status we require that you upload proof in the form of an image/PDF.

Types of proof


Student ID Card, Letter of enrollment, or similar


Teacher ID Card, Lecturer ID Card, Payslip, Letter from the school/college

Education proof is submitted to the manufacturer and is accepted at their discretion.

The Basics

iLok is a copy protection method used by many of our brands.

It has 3 types of activations, iLok USB, iLok Machine, and iLok Cloud.

Different brands/products will offer different iLok methods. iLok USB is always an option, but the availability of iLok Cloud and iLok Machine methods is at the discretion of the software developer.

iLok Account

For all iLok protected products, you will need an iLok account. You can create one for free here: ilok.com/#!registration

iLok License Manager

To manage your iLok licenses, there is a dedicated app called iLok License Manager. This app is used to register, activate, and move your licenses between locations.

You can download the latest installers from the iLok website: ilok.com/#!home

iLok USB Key

iLok USB

This activation is stored on an iLok 2 or 3 USB key.

It is the best option for portability, if you frequently move between multiple machines, and offline use.

iLok Machine ID

Machine ID

This activation is stored locally on your computer.

While this is a convenient way to work offline, and does not require the additional cost of an iLok USB, there is the risk of a license being lost in the case of a drive failure.

This option also requires extra care when you upgrade to a new computer, the license(s) must be deactivated on your old machine first to ensure you do not lose them.

iLok Cloud

iLok Cloud

This activation is based online, and requires a "cloud session" using the iLok License Manager.

It requires an active internet connection for the entire time you use the plugin(s).

ZeroBox is an accurate analog modeled 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, analog 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 behavior 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 analog oscillator's waveforms to the iconic 4-pole diode ladder analog 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 analog-modeled vacuum tube distortion unit, an analog-modeled transistor-based distortion unit, a digital foldback distortion unit, a creative bitcrusher unit, a digital delay unit, and a resonator-based reverb unit.


  • 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 analog technology.
  • Full 64-bit processing accuracy for every single aspect of the simulation.
  • An all-in-one complete setup: monophonic analogue bassline synthesizer + embedded analog sequencer + analogue and digital insert/master effects
  • Full preservation of all quirks found on the original device:
    • The legendary gimmick circuit and its signal paths
    • The analog 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 analog circuits, featuring sawtooth and square waveforms with blending (morphing) control
  • A separate control for the oscillator waveshaping (from naive to analog supersaw / pulse width modulation)
  • A legendary 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 analog envelope generators (MEG / VEG) proving the same capacitors' charging/discharging responses as found on the original analogue circuits
  • Analog 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

    • 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
