Ever since it’s introduction in 2004, Stylus RMX has been an award-winning loop-based virtual instrument plug-in featured on thousands of major productions. RMX emerged as the first product to offer the combined power of Groove Control® with Spectrasonics Advanced Groove Engine (S.A.G.E.™) technology giving users dramatic control over loop-based groove production – with dozens of innovative features including the ground-breaking Time Designer® and Chaos Designer®. RMX remains an industry standard tool of many top composers and music producers.

Unsurpassed Innovations
Of the many remarkable capabilities in Stylus RMX Xpanded, possibly the most innovative features are the Time Designer® and Chaos Designer®. With simple controls, the user can introduce musical Chaos into the groove, which allows it to have constantly evolving variations— giving the impression that the audio grooves are improvising. The results can be subtle or extreme by setting the simple to use controls. A Capture feature allows the spontaneous audio chaos patterns to be made into a MIDI file, dragged and dropped into the host sequencer, and played back again for further editing by the user. The Time Designer feature is unmatched in any other rhythm software and allows realtime changing of audio grooves to any time signature, feel or pattern – an infinite creative tool!

Core Library
The highly acclaimed core library in Stylus RMX Xpanded has thousands of cutting-edge grooves and sounds that were created by Spectrasonics’ international sound design team, and produced by Eric Persing. The core library contains nearly triple the amount of sounds originally offered in the original Stylus, and contains all the original material as well. The sounds and grooves in Stylus RMX Xpanded offer a much wider range of modern musical genres than the original Stylus. Mixes of grooves are broken down into individual tracks called Elements for flexibility and infinite combinations.

Xpanded and Xpandable
Stylus RMX Xpanded now includes all five Spectrasonics “S.A.G.E. Xpanders”, bringing the total number of included grooves/sounds to nearly 10,000. The RMX platform has huge third-party library support with hundreds of available titles and can also can be expanded with REX files – which opens the door for musicians to utilize their own audio loops within the powerful S.A.G.E. Environment.

Which libraries are included with Stylus RMX Xpanded?
The entire core library in Stylus RMX Xpanded is specially created for this virtual instrument.

Also included is the “Bonus Spectrasonics” library – which includes all of the Vocal Planet and Bizarre Guitar Groove Control material, a large selection of loops from the Distorted Reality libraries and more previously unreleased material.

Is Stylus RMX Xpanded only useful for Electronic styles?
RMX stands for “Remix”, so of course the focus of the core library is definitely on sound design and modern sonic elements. However, there is also a nice “hi-fi” selection of percussion loops and many single hit menus for use in many more traditional styles and the included Sage Xpander libraries have much more organic material. Because of the flexibility of Groove Control and the wide variety of single hits, Stylus RMX Xpanded has been successfully used in many traditional pop and rock settings too. There have been numerous hit records and filmscores that have featured the Stylus RMX core library in a vast array of genres. We’d recommend checking out the uses of Stylus RMX Xpanded on the audio demos page to hear it in a wide variety of styles.

Does Stylus RMX Xpanded have Kits and Playable sounds?
Stylus RMX Xpanded includes an extensive collection of over 250 hundred simple electronic Kits, over 3,000 kit modules and over 10,000 one-shot single hits in “Sound Menus” – all of which are great for creating your own completely custom rhythm tracks. The focus of the sounds are decidedly in the “modern remix” category. Although you won’t find many “traditional” acoustic sounds with extensive multisampling, there is a nice section of acoustic percussion and some hi-fi cymbals too.


What is Stylus RMX Xpanded?
It’s a Virtual Groove Module plug-in, which combines a massive 14 gigabyte core library with a powerful, yet easy to use interface for manipulating the sounds in unique and innovative ways. It includes all five Spectrasonics SAGE Xpander libraries (previously sold separately.)

So is Stylus RMX Xpanded basically a “preset” loop machine?
Not at all. The whole idea is to combine powerful flexibility, with an easy to use interface. You can easily think of RMX as the ultimate Groove creation machine! Because of the power of Groove Control™, you can easily create and manipulate your own grooves using the core library as a starting point for your own explorations. It is not an exaggeration to say that there are millions of possibilities. Stylus RMX Xpanded is designed to be inspiring for many years to come.
