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:!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:!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).

Our definitive acoustic guitar rhythm instrument! Acoustic Revolutions: Strum Designer (formerly: Acoustic Revolutions 3) gives you the convenience of loops with the ultimate in flexibility, so that you can quickly write entire background tracks in virtually any key, chord, or tempo, using a single instrument.

Acoustic Revolutions: Strum Designer is ISW's definitive rhythmic acoustic guitar library.

More than just a collection of loops, Strum Designer gives you the tools to build complete rhythm parts in virtually any chord progression, key, and tempo.

You'll find amazing versatility in these loops, which can sit easily in soft rock, epic ballads, edgy pop, dance, folk, easy listening, and even world genres.

We've exhaustively sampled 48 unique strummed rhythms in two tempos, six keys, twelve chord types, and multiple variations per rhythm.

As a result, you can use the performances in virtually any composition with minimal stretching or shifting needed.

Strum Designer lets you produce beautiful, natural rhythmic guitar parts within minutes.

Choose from 12 different chord types such as major, minor, 7ths, augmented (etc) via keyswitch or intelligent chord detection, then easily select patterns by tapping a single key.


Host-Synced Playback

Phrases can sync to host BPM, with seamless transitions between chords and patterns.

True Doubletracking

Get a true, wide stereo sound with two completely unique A/B variations, or just use one at a time.

Multiple Playback Modes

Choose from intelligent chord detection, manual key and chord input, or selection based on diatonic scale degree.

Analog and Digitally-Modeled FX

Get quick mix results with the included compressor, EQ, chorus, delay, convolution reverb, and limiter.

Over 14,000 24-bit recordings - Available both in the Kontakt instrument, and as standalone WAV loops.48 Inspiring Rhythm Patterns

Build your track from a selection of bread-and-butter rhythms in 4/4, 3/4, and 6/8.

Play Virtually Any Chord in Any Key

Create nearly any progression you can think of with twelve recorded chords for every pattern, playable in any key.

Great for Any Genre

With a huge variety of rhythms, Strum Designer works great for rock, pop, singer-songwriter, country, EDM, and beyond.

How It Works

This Kontakt Player library gives you many ways to perform, sequence, and switch between rhythms and chords seamlessly.

While all loops are also provided in WAV format, Strum Designer provides three convenient ways to musically control its huge bank of over 13,000 loops.

In all three modes, patterns are selected via keyswitch:

For those less comfortable playing chords on their keyboard controllers, manual mode allows you to select a chord root and chord quality with a single keyswitch each.

Intelligent mode will detect the chord (root and quality) you play on your keyboard.

For those seeking the ultimate in rapid production, auto chord mode narrows your choices to diatonic chords within an octave.

Select your key and scale quality, then use keyswitches to select diatonically mapped chords, allowing you to easily create chord progressions that fit smoothly together.

Adjust playback to sync with your host, trigger transitions like chokes, falls, stops, and mutes, and even apply up to 6 FX from our modular analog/digital effects rack.

Whether you're writing pop, rock, country, underscore, or EDM, the Strum Designer’s far reaching content is sure to inspire your productions!
