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).

OB-Xd is a classic synthesizer with a timeless sound that continues to captivate musicians and producers alike.

With its rich, full-bodied tones and expansive sound design capabilities, the OB-Xd is the perfect choice for those looking to add a vintage touch to their music.

Whether you're producing electronic tracks, recording live instruments, or composing for film and television, the OB-X is an invaluable tool that will bring a unique and expressive quality to your sound.

The OB-Xd is a synthesizer that has been designed to recreate the sound and behavior of the Oberheim OB-X.

However, the original design of the OB-X was limited in some ways, so the OB-Xd includes a number of additional or altered features.

One key feature of the OB-Xd is its implementation of micro random detuning, which helps to create a fuller, richer sound.

Overall, the OB-Xd has been designed to produce a sound that is as good and as rich as the original OB-X.

While not copying originals, some of the features were taken to a better point.

Continuous blendable multimode filter (HP-Notch(BP)-HP in 12 dB mode and 4-1 pole in 24 dB mode).

Also, like many synths of the OB-X's generation, the OB-Xd has no internal effects so its sounds and textures can be greatly enhanced by the use of additional processing like chorus, reverb, delay, etc.

Additionally, for those interested in micro-tuning, the OB-Xd comes equipped with support for MTS-ESP.

This allows for more granular control over your tuning adjustments, perfect for the discerning synth musician.

What's New in OB-Xd 3

Enhanced Oscillator Features

The update introduces new Pulse Width Modulation Controls for intricate sound shaping, enhancing the sonic possibilities of the oscillators.

  • PW Offset: Adjusts the pulse width of Oscillator 2 with a unipolar knob based on the PW knob's setting.
  • PW Env: Modulates Oscillator 2's pulse width with the Filter Envelope.
  • PW Env Both: 1+2 button allows the Filter Envelope modulation to affect both oscillators' pulse width.

Advanced Filter Capabilities

Including Self-Oscillation, Filter Falloff Adjustment, and Adjustable Filter Envelope Shape, providing more control and variety in sound filtering.

  • Self-Oscillation: The 12dB filter now self-oscillates at high resonance levels.
  • Filter Falloff Adjustment: A new FLT CMP knob in the Voices section influences cutoff scaling.
  • Adjustable Filter Envelope Shape: Blends between exponential and linear shapes for the attack.
  • Filter Envelope Inversion: A new button for inverting the Filter Envelope output.
  • Enhanced Filter Keytracking Control: A refined knob offers precise control over the filter's response to keyboard tracking.
  • Level Difference Knob: Ensures consistent audio output during filter adjustments.

Refined Attack Envelope Shape

This feature introduces a sophisticated logarithmic-linear attack slider, offering unparalleled flexibility for dynamic sound sculpting.

The slider enables users to precisely control the attack phase of sounds, ranging from subtle, gentle slopes for softer onsets to sharp, aggressive inclines for more pronounced attacks.

This dual-mode approach allows for a wider array of sonic textures, providing musicians and producers with the tools to tailor the attack characteristics of their sounds, whether they're aiming for a natural, smooth progression or seeking a more abrupt, impactful onset.

Oversampling Selection

Available in the registered version, this feature offers options for different sound quality requirements, including no oversampling (1x), 2x, or 4x.

MIDI and Preset Bar Enhancements

Improved usability and functionality, making it easier to manage and access MIDI controls and presets.

LFO Synchronization

Ensures perfect timing by syncing the internal LFO with your DAW's BPM.
