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).

The Vintage Tape Delay You've Been Waiting For

The Echoleffe Tape Delay is an enhanced model of a fabulous, all-tube tape delay from 1961.

It adds effortless character and vintage mojo to your recordings and mixes, but it's TONS more than just a tape delay.

Three different operational modes give you delay effects, tape saturation and a tube preamp.

Tape Delay Mode

The EDT is a fantastic tape delay simulation with unmatched versatility.

From pristine vocal echos to outer space flange effects, the ETD is a tool that brings out your creativity.

Tape Saturation Mode

Tape Saturation mode switches off the delays and turns the ETD into a dedicated tape saturator.

Add a gentle warmth or crank up gain and wow and flutter for unheard of effects.

Tube Preamp Mode

The ETD's tube preamp simulator adds a gorgeous warmth and richness to any signal you pass through it.

No delay, no saturation, just pure tube preamp glow... or crank up the gain and make things explode.

It's a Tape Delay

The Echoleffe Tape Delay features three delay lines that can be independently panned across the stereo field, EQ'd and tweaked for effects ranging from tight to massive.

Sync to your DAW, so your time settings can be based on music note values and perfectly synched to your music.

Or manually set any of the delay lines for up to 4 seconds for out of this world spacial effects.

Beyond just delay, we've included extensive controls so you can tweak the age of the tape, simulate wearing out motors and tape heads and change tape formulations.

Set Wow and Flutter for flanging and detune effects, create reverbs that shimmer and move, or nail the guitar sounds of your favorite players.

The Echoleffe is massively versatile and fun to use.

It's a Tape Saturator

Top engineers often cut critical tracks on analog tape to get the sound of tape saturation.

Tracks recorded to analog tape tend to sit better in the mix, thanks to the gentle compression and sweet harmonics that come from tape saturation.

Now you can get that sound on your mixes using the ETD.

Adjust all parameters - from gain to bias to tape formulations and age.

The EDT can be as gorgeous as a vintage analog tape deck, or as crunched and nasty as you want it to be.

It's a Tube Preamp

The heart of any audio system is its preamp.

The EDT's preamp is a precise recreation of a tube circuit from the late 1950s that sounded so good it was made into a guitar amp.

Our EDT gives you complete control of that tube circuit so you can further tailor the sound of your delays, or use just the preamp to warm up a track or create a unique fuzz tone.

Strap it across the mix bus, fix a thin bass.

The ETD tube preamp mode gives you simple yet effective controls to get that sound in your head.
