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).

This sets it apart from all the other common analog synth recreations.

You have instant access to hundreds of different analog modeled & free running oscillator waveforms, and they can be dynamically modulated by many sources.

Two gorgeous, creamy multimode filters, self-resonating in all modes, and Xils exclusive 0df technology.

In addition, you get two gorgeous, creamy multi-mode filters, self-resonating in all modes, and Xils exclusive '0df' technology.

There are also three Analog modeled envelopes, with time multiplication, and great looping capabilities.

Two complex LFOs are available with MIDI sync capabilities.

All working to deliver a fat, warm and immediately inspiring analog sound.

Features

  • 3 Morphing oscillators
  • 2 Creamy Multimode 0df Filters
  • 3 Envelopes, 2 LFOS
  • Polysequencer, arpeggiator, vintage effets
  • Unmatched analog presence and feeling
  • Tomorrow's technology: Hundreds of modulation, including 2 Unique Per voice modulators, a supersized step sequencer, and two Mod Matrixes

Per Voice

It wouldn't be an XILS-lab instrument if it didn't have innovative and exclusive features like each voice having its own modulation engine, or a giant Step Modulator, to propel it into the 21st century.

Make Each Note Different

The Voice XY module is a single Note Quad XY modifier playground.

You have total control over the creation of subtle or wild variations for each note in a 2D square with 4 different parameters.

Create Your Own 3D Space

With the Space XY module, you can place each note in a three-dimensional space, and build stereo-scapes that no other effect can achieve.

On top of that, you can make it move with the inbuilt chaotic functions, adding incredible life to your sounds.

You have never had so much artistic control over the stereo field.

If you combine these two Single Note modifiers with the True Unison engine, you’ll soon get amazing, dense, and breath-taking sounds, that will proudly take their place in a mix immediately.

Operating it is easy, you simply place and move control points of the voices, in the square.

Hyper Modulations

The Polysequencer can now be used as a 128 steps, 4 lines/16 destinations giant Step Sequencer Modulator, allowing you to sculpt not only the most detailed TranceGate patterns, but also Slides or incredible rhythmic patterns.

Everything is here to allow you to create fully organic and expressive presets.

PolyKB III is the ultimate blending of analog authenticity and powerful modern technology.
