Spectrasonics products are virtual instrument plugins that can also run as standalone applications. Omnisphere 3, Keyscape, Trilian, and Stylus RMX Xpanded can be used inside a DAW (Digital Audio Workstation) such as Pro Tools, Logic Pro, Cubase, Ableton Live, Studio One, Reaper, or any other AU, VST3, VST2, or AAX-compatible host. Omnisphere 3 FX can also be instantiated as an effects plugin suite inside most DAWs.

After installing and authorizing your Spectrasonics instrument, instantiate it as a virtual instrument plugin on an instrument track inside your DAW. Spectrasonics provides step-by-step setup walkthroughs for every major host inside their Knowledge Base under "Adding Instruments to DAW."

The Spectrasonics User Account is where you register your instruments and access downloads, authorizations, additional installations, and updates. Register every Spectrasonics serial number to your account so you can re-authorize a new computer, redownload installers at any time, and receive SmartUpdate notifications.

Yes. All four flagship Spectrasonics instruments (Omnisphere 3, Keyscape, Trilian, and Stylus RMX) run natively on Apple Silicon processors including the M1, M2, M3, and M4 families. Native Apple Silicon support has been in place since the June 2021 free update. The instruments also continue to run natively on Intel Macs.

The current versions of Keyscape, Trilian, and Stylus RMX Xpanded are officially supported on macOS Tahoe 26, Sequoia 15, Sonoma 14, Ventura 13, and Monterey 12. Omnisphere 3 requires macOS Ventura 13 or higher.

Beta or unreleased macOS versions are not supported. Always wait for the official Apple release and the corresponding Spectrasonics compatibility confirmation before upgrading your audio production system.

Windows 10 and Windows 11 (64-bit) are both supported. Older Windows versions are not. As with macOS, beta Windows builds are not supported for audio production.

The current versions of Omnisphere 3, Keyscape, Trilian, and Stylus RMX Xpanded all support AU (macOS only), VST3, VST2, and AAX, all 64-bit. Any 64-bit DAW that hosts one of these plugin formats can load the instruments.

Omnisphere 3 requires a 2.4 GHz or faster processor, 8 GB of RAM minimum (16 GB or more recommended), 64 GB of free hard drive space for the core library, macOS 13 Ventura or higher, or Windows 10 or higher, and a 64-bit DAW that hosts AU, VST3, VST2, or AAX plugins. An SSD is strongly recommended for streaming the patch library.

The Omnisphere 3 core library uses lossless compression and ships with thousands of additional sounds across 18 new libraries without increasing the disk footprint above the previous Omnisphere 2 size. The library still occupies approximately 64 GB of disk space.

Yes. Omnisphere 2 continues to be officially supported on macOS Tahoe 26, Sequoia 15, Sonoma 14, Ventura 13, Monterey 12, and Big Sur 11. New compatibility work going forward will focus on Omnisphere 3, so Omnisphere 2 owners who want continued long-term macOS coverage should consider the upgrade.

A solid state drive (SSD) is strongly recommended for the Spectrasonics core libraries. Streaming the multisampled Soundsources benefits substantially from the faster random access of an SSD over a spinning hard drive. The drive must be formatted with a modern filesystem (APFS or HFS+ on macOS, NTFS on Windows). FAT32 and exFAT are not recommended because of their file size limits.

An external SSD connected over USB 3, USB-C, or Thunderbolt is fully supported and is a practical way to keep the libraries on a single drive that can be moved between a studio computer and a laptop.

Spectrasonics' legacy products are no longer in active development and are not compatible with current 64-bit operating systems. The Spectrasonics Knowledge Base has a Legacy section covering installation, authorization, and troubleshooting for owners who still have a working legacy system. Atmosphere owners qualify for a special discounted upgrade path to Omnisphere 3 (see the Upgrades section).

Omnisphere 3 introduces a substantial expansion of the synthesis engine and library, including:

• Quadzone Modulation for dramatic timbral movement across four layered sound sources
• 36 new filter types organized into seven distinct sonic colors
• Circuit-modeled saturation for warm analog coloration
• The world's first polyphonic dual frequency shifter
• Vintage Oscillator Drift modeling analog instability
• Patch Mutations for generating instant variations of any sound
• Adaptive Global Controls (Tone, Ambience, Filter, Envelope, Vibrato, Unison) for quick sound shaping
• 18 new sound libraries containing thousands of new patches
• 300+ hardware synth profiles, including modern instruments such as the Moog One, Hydrasynth, Roland Jupiter-X, and Oberheim OB-X8
• 35+ new effects units including Super Verb, Velvet Verb, Multiband Compressor, and vintage tape and console emulations
• A standalone Omnisphere FX Rack plugin for using Omnisphere's effects on any track
• MPE support for expressive control from MPE controllers

All projects from Omnisphere 1 and Omnisphere 2 open and play back natively in Omnisphere 3.

The Standard Upgrade is for owners of Omnisphere 1 or Omnisphere 2 who want to move up to Omnisphere 3. The upgrade includes the full Omnisphere 3 software and library.

Atmosphere was Spectrasonics' Dream Synth Module released in 2002 and discontinued in 2008. As a courtesy to long-time Atmosphere owners, Spectrasonics offers a special discounted upgrade path from Atmosphere directly to Omnisphere 3. Both the Standard Upgrade and the Atmosphere Upgrade deliver the full Omnisphere 3 product.

Important: customers who take advantage of the Atmosphere Legacy Upgrade are not permitted to resell either Atmosphere or Omnisphere 3, and no license transfer will be granted on either product. The Standard Upgrade does not carry this restriction.

No. The Omnisphere FX Rack is included with Omnisphere 3 at no additional cost. It loads as an AU, VST3, VST2, or AAX audio effects plugin and exposes the same effects engine and effects rack used inside the Omnisphere synthesizer, with four effects slots in series, for use on any audio or instrument track in your DAW.

Yes. Omnisphere 3 supports MPE (MIDI Polyphonic Expression) for expressive performance from controllers such as the ROLI Seaboard, Haken Continuum, LinnStrument, KMI K-Board Pro 4, and Sensel Morph.

Yes. The Hardware Library is expanded in Omnisphere 3 with 300+ hardware profiles that turn the included supported hardware synths into hands-on controllers for Omnisphere. The library covers historic and modern instruments from Access, Korg, Moog, Novation, Oberheim, Roland, Sequential, Yamaha, and many others. Existing Omnisphere 2 hardware profiles continue to work.

Omnisphere 3 is available from ILIO as the USB Drive Edition on the Spectrasonics product pages. Standard Upgrades and Atmosphere Upgrades are listed alongside the full product.

Keyscape is a deeply sampled virtual instrument featuring 36 carefully restored collector keyboards, from rare grand pianos to legendary electric pianos, vintage Clavinets, harpsichords, Mellotrons, and other instruments. Each keyboard was found, restored, and multisampled by the Spectrasonics Sound Development Team. The result is a library of hundreds of expressive patches built for serious players.

Keyscape includes 36 instrument models covering acoustic grand pianos (including the LA Custom C7 grand and Wing Grand), Rhodes-style and Wurlitzer-style electric pianos, Clavinets, harpsichords, Mellotrons, toy pianos, and other rare keyboards. The full list of every instrument is on the Library tab of the Keyscape product page.

Hybrid Duo Sounds are a special category of Keyscape patch that combines two of the included instruments into a single layered timbre. The result is a new sound that doesn't exist on either original instrument alone. Many Keyscape users find the Duo patches some of the most creative and inspiring material in the library.

Yes. Keyscape integrates fully as a satellite instrument inside Omnisphere. Once both instruments are installed and authorized, you can browse and load Keyscape patches from within the Omnisphere interface and apply Omnisphere's deep synthesis, modulation, and effects to the Keyscape sounds.

The Keyscape Creative Library is a free included expansion of more than 1500 patches specifically designed for users who own both Keyscape and Omnisphere. The patches take the Keyscape collector keyboard sounds and run them through Omnisphere's synthesis engine for textures, hybrids, pads, and modern production-ready sounds that go far beyond traditional keyboard timbres.

Yes. Keyscape ships with an optional "Lite" installation that takes 30 GB instead of the full 80 GB, intended for stage and laptop rigs where disk space is limited. The Lite install includes a curated subset of the library sized for live performance use.

Keyscape requires a 2.4 GHz or faster processor, 8 GB of RAM (or more recommended), and 80 GB of free hard drive space (30 GB for the Lite install). An SSD is recommended. Supported operating systems are macOS 10.15 Catalina or higher and Windows 10 or higher (64-bit). Keyscape runs as AU, VST3, VST2, or AAX in a 64-bit host. Apple Silicon native and Intel are both supported.

Trilian is a virtual bass instrument plugin combining deeply sampled acoustic bass, more than 60 electric bass variations, and a substantial synth bass section. The library covers fingered, picked, fretless, slapped, tapped, and muted technique variations, with extensive legato and glide articulations and modeled mechanical noises and release overtones for authentic playing realism.

Trilogy was Spectrasonics' original bass module released in 2002. Trilian is its modern replacement and is built on a fundamentally larger sample foundation, roughly ten times the size of Trilogy. All original Trilogy samples are included inside Trilian, alongside the remastered Bass Legends content featuring Abraham Laboriel, Marcus Miller, and John Patitucci, and the much larger acoustic and electric bass library. Trilogy is a discontinued legacy product.

Yes. Trilian integrates fully as a satellite instrument inside Omnisphere. Trilian patches appear inside Omnisphere's browser and can be processed through Omnisphere's synthesis engine, modulation, and effects.

The Trilian Creative Library is a set of more than 200 patches specifically designed for users who own both Trilian and Omnisphere. The patches take Trilian's bass content and combine it with Omnisphere's synthesis for hybrid, processed, and texture-oriented bass sounds beyond the standard articulation library.

Trilian includes 33 effects units covering compressors, equalizers, filters, distortion, reverbs, delays, and modulation effects. The Enhanced Arpeggiator adds Humanity and Life controls, chord voicings, and pitch slides for expressive bass patterns. Flow Capture, Trilian's standalone recording feature, captures audio, MIDI, and the native .trilian sound format simultaneously for fast idea capture.

Trilian 1.5 added many of Omnisphere's synthesis functions to the engine, introduced a Live Mode interface optimized for touch screens, added Multis for splits and layers, and brought a HiDPI-ready resizable interface. The 1.5 update is free to all registered Trilian owners.

Trilian requires a 2.0 GHz or faster processor, 8 GB of RAM (or more recommended), and 36 GB of free hard drive space. Supported operating systems are macOS 10.15 Catalina or higher and Windows 10 or higher (64-bit). Trilian runs as AU, VST3, VST2, or AAX in a 64-bit host. Apple Silicon native and Intel are both supported.

Stylus RMX Xpanded is a loop-based virtual instrument built around Spectrasonics' S.A.G.E. (Spectrasonics Advanced Groove Engine) technology and Groove Control. It pioneered tempo-independent groove manipulation in the DAW and has appeared on thousands of major productions since its 2004 introduction. The Xpanded edition includes a 14 GB Core Library, all five Spectrasonics SAGE Xpanders, and the original Stylus core library.

Yes. Spectrasonics has classified Stylus RMX as a legacy instrument, but it remains fully functional on current operating systems and continues to receive maintenance updates. Spectrasonics has committed to keeping Stylus RMX working for the foreseeable future so existing sessions continue to open and play back. Stylus RMX Xpanded is available from ILIO as a special order item.

Five Spectrasonics SAGE Xpanders are included at no additional cost: Backbeat, Retro Funk, Liquid Grooves, Burning Grooves, and Metamorphosis. Each Xpander adds its own curated library of S.A.G.E.-formatted grooves and edit groups for use inside Stylus RMX.

Chaos Designer is Stylus RMX's algorithmic variation engine that introduces musical changes inside stereo audio grooves, adding life and "improvisation" to otherwise static loops. Time Designer lets a groove adapt to any feel or time signature, including swing, shuffle, and odd meters, without breaking the original audio. The two systems work together for production-ready groove flexibility.

Yes. Stylus RMX supports REX file import alongside its native S.A.G.E. format. Once a REX file is loaded, it can be edited, processed, and rearranged using Stylus RMX's full feature set including Chaos Designer, Edit Groups, and the integrated effects.

Edit Groups are Stylus RMX's per-slice control system for audio loops. Each slice in a groove can be assigned to an Edit Group, allowing independent control of pitch, level, panning, reverse, ambience, or effects on specific elements within a stereo audio loop without destructive editing. Common uses include adding reverb to only the backbeat, retuning the snare inside a stereo loop, or reversing specific slices.

Stylus RMX requires a 2.0 GHz or faster processor, 4 GB of RAM minimum, and 15 GB of free hard drive space. Supported operating systems are macOS 10.15 Catalina or higher and Windows 10 or higher (64-bit). Stylus RMX runs as AU, VST3, VST2, or AAX in a 64-bit host. Apple Silicon native and Intel are both supported.

Sonic Extensions are official expansion libraries created by Spectrasonics and a small group of select sound designers. Each Extension installs inside Omnisphere and appears alongside the core library in the patch browser. Beyond new patches, each Extension also ships with custom interface controls and two new effects tailored to that library's sound.

The current Sonic Extensions lineup includes:

• Nylon Sky: ambient acoustic guitar textures, developed by Spectrasonics
• Seismic Shock: heavy modern electronic sound design, developed by Spectrasonics
• Unclean Machine: lo-fi and retro tones, developed by Spectrasonics
• Undercurrent: dark electronic scoring, developed by Ignacio Longo
• Twisted Trees: organic dreams and dark cinematic textures, developed by Diego Stocco

Sonic Extensions require Omnisphere 3 or Omnisphere 2.8 or higher, installed and authorized on your computer. Omnisphere 1 is not compatible. Omnisphere 2.7 and earlier are not compatible. Both your parent Omnisphere license and each Sonic Extension must be registered to the same Spectrasonics User Account.

After purchase, the Sonic Extension installer is available from the Reinstall area of your Spectrasonics User Account. Run the installer and choose either "Install Sounds + FX" (full install) or "Install FX only" (for systems where library disk space is constrained). Re-authorize Omnisphere after installation so the new Extension is recognized. The Extension's patches then appear in Omnisphere's Patch Browser under the Directory view.

The Sonic Extensions store requires that you have Omnisphere 3 or Omnisphere 2.8 or higher registered to your Spectrasonics User Account, installed on your computer, and authorized. If you own Omnisphere 1, upgrade to Omnisphere 3 first. If you meet the conditions and still cannot purchase, contact Spectrasonics directly at sales@sonicextensions.com.

Sonic Extensions are maintained through Omnisphere's SmartUpdate system. When SmartUpdate runs, it includes any available updates for your installed Extensions alongside updates for Omnisphere itself.

An Update is a free maintenance release that delivers fixes, compatibility improvements, and small enhancements within the same major version (for example, Omnisphere 3.0.0 to 3.0.2, or Keyscape 1.5.1 to 1.5.2). Updates are always complimentary and are delivered through SmartUpdate or your Spectrasonics User Account.

An Upgrade is a paid move from one major version to the next (for example, Omnisphere 2 to Omnisphere 3). Upgrades introduce significant new features and a new library, and are sold as separate upgrade products through ILIO and Spectrasonics.

SmartUpdate is built into Omnisphere 3 and Keyscape. When you launch one of those instruments with an internet connection, SmartUpdate checks every Spectrasonics instrument and library installed on your computer and reports any available updates on the splash screen. Clicking GET UPDATES takes you to a SmartUpdate page on spectrasonics.net that compiles every needed update into a single download, then runs one installer that brings the entire Spectrasonics suite up to date in one pass.

Sign into your Spectrasonics User Account and open the Updates tab. Every available update for every registered Spectrasonics product is listed there with installer downloads for both macOS and Windows.

For Omnisphere, Keyscape, and Trilian, click the Spectrasonics logo in the upper-right corner of the plugin interface to display the current software, soundsource, and patch library versions. For Stylus RMX, open the Utility Menu (floppy disk icon in the lower right) and scroll to the bottom for the version display.

Spectrasonics uses a Challenge and Response authorization system. After installation, open the instrument and choose Request Authorization. The plugin generates a Challenge Code unique to your computer. Submit that Challenge Code to the Spectrasonics Authorization portal at auth.spectrasonics.net and you receive a Response Code that completes authorization. The portal is self-service and available 24 hours a day.

Yes. As the sole user of your license you may install and authorize your Spectrasonics instruments on every computer you personally use, including a studio desktop, a laptop, and replacement machines. The license is per-person, not per-machine.

Reauthorize on the new computer using the standard Challenge and Response process. There is no need to deauthorize the previous machine, and there is no per-authorization limit for an honest single user. Spectrasonics maintains anti-theft safeguards similar to credit card protocols and may occasionally request additional verification.

No. Spectrasonics uses its own Challenge and Response authorization system. No iLok, USB dongle, or external hardware key is required at any point. The USB Drive Edition's USB drive is the installation media only and is not needed after the installer has run.

Spectrasonics supports offline authorization. Open the instrument on the offline computer, choose Request Authorization, and write down or photograph the Challenge Code. On any other internet-connected device, sign into your Spectrasonics User Account, go to the Authorization area, enter the Challenge Code, and receive the matching Response Code. Type the Response Code back into the offline computer to complete authorization. The Spectrasonics Knowledge Base has a step-by-step walkthrough under "How to Authorize your Instrument Using an Offline Computer."

There is no fixed per-license authorization counter for honest single users. As the sole user of your license, you can authorize each of your own computers as you set up a new studio machine, a laptop, a replacement system, or a backup rig. Authorization is intentionally generous so that legitimate single-user setups are never blocked. Spectrasonics monitors for unusual patterns and may occasionally request additional identity verification to protect against theft.

Occasional reauthorization can be triggered by major operating system upgrades, hardware changes, drive reformatting, or routine identity verification. Reauthorizing is a fast Challenge and Response cycle through your Spectrasonics User Account. If you see the authorization screen unexpectedly and have made no recent system changes, contact Spectrasonics support.

When a satellite instrument or Sonic Extension is first accessed from inside Omnisphere, Omnisphere itself triggers the authorization process for the additional product. The Challenge and Response flow is identical to authorizing Omnisphere on its own. The Spectrasonics Knowledge Base has detailed walkthroughs for authorizing Keyscape, Trilian, and Sonic Extensions inside Omnisphere.

No. Spectrasonics guarantees lifetime authorization for licensed users and maintains contingency systems so that authorization will remain available regardless of changes in the company over time. Your purchase is a lifetime license, not a subscription.

The Spectrasonics standard license is a single-user license for musical use:

• Single-user music production and performance: Allowed
• Multiple users sharing one license: Not Allowed
• Non-music applications: Not Allowed without separate written clearance
• Use to train artificial intelligence systems: Not Allowed

Any usage that falls outside the standard license requires separate permission from Spectrasonics. Contact info@spectrasonics.net for non-music licensing inquiries.

A single user is one specific person. The license cannot be owned by, or shared across, a company, corporation, organization, band, partnership, school, studio, or any other entity composed of multiple people. Each individual using the instrument needs their own license.

Yes. The lifetime license fee is included in the purchase price. There are no additional royalties, no per-project fees, and no track-count limits. Use the instruments on as many commercial recordings, song placements, music libraries, beats, stems, trackouts, cues, and melody or chord packs as you like.

No. A credit is not required, though Spectrasonics certainly appreciates one when you choose to include it.

Yes. Many soundware companies restrict use in music libraries because libraries sometimes overlap with the soundware business, but Spectrasonics specifically allows this use. Many Spectrasonics customers run successful music library businesses built on these instruments.

Normal musical use is not a concern. Spectrasonics sounds frequently appear in exposed intros, breaks, beds, and solo passages within a finished mix. That is considered normal use and falls inside the standard license.

Yes. Some soundware companies restrict trailer use, but Spectrasonics specifically permits it under the standard license.

Yes, when the use is musical. Composing the score or the in-game music with Spectrasonics instruments is fully permitted under the standard license. What requires a separate license is encoding the actual audio samples directly into a game engine, app, or interactive system as sound effects or one-shots. Contact Spectrasonics if you need to embed sounds into a game or application.

No. The Spectrasonics license expressly prohibits using the instruments or their sounds to train artificial intelligence systems of any kind. This includes generative music models, sample-based AI tools, and any machine learning system where Spectrasonics audio would be ingested as training data.

Non-musical use (for example, sound design for film SFX, app sound effects, branded audio identities outside a musical context, or interactive product sounds) is not covered by the standard license. Contact Spectrasonics at info@spectrasonics.net in advance to discuss non-musical licensing. Many non-musical uses can be cleared with a separate arrangement, but they need to be cleared in writing first.

Individual students may qualify for educational pricing from ILIO. Contact ILIO's sales line at 818-707-7222 to see if you qualify. Qualifying schools and institutions can participate in the Spectrasonics EDU program for institutional site-license pricing. Contact Spectrasonics directly to discuss qualification.

License transfers are reviewed on a case-by-case basis and are not guaranteed. Only the original purchaser can initiate a transfer, and a license can be transferred only once in its lifetime. Submit your transfer request to info@spectrasonics.net. Processing typically takes a few weeks.

Yes. Spectrasonics charges a transfer processing fee of $50 USD per instrument. Customary practice is for the seller to pay the transfer fee as part of the sale, but the parties involved can decide that between themselves.

No. Sonic Extensions cannot be transferred on their own. They can only be transferred bundled with an approved transfer of the parent Omnisphere license.

No. SAGE Xpanders cannot be transferred individually. They can only be transferred together with an approved transfer of the parent Stylus RMX Xpanded license.

Yes. Three categories of license cannot be transferred:

• Omnisphere 3 licenses obtained through the Atmosphere Legacy Upgrade. Atmosphere upgrade customers are not permitted to resell either product.
• Spectrasonics one-shot sound library products (the classic sample libraries).
• Any license already transferred once. A license can only change hands a single time.

The Spectrasonics license is granted for the lifetime of the licensed user. If a licensee passes away, their family can contact Spectrasonics for case-by-case consideration.

Yes, without restriction. The standard license covers distribution of your finished musical work in any form: audio files, mixes, stems, trackouts, multitracks, beats, cues, songs, albums, EPs, music library tracks, scores, sync placements, and so on. The lifetime music distribution license is included in the purchase price.

No. The Spectrasonics Core Libraries are copyrighted sound recordings and cannot be redistributed as sample content. Spectrasonics summarizes this policy with the phrase "a snare is not a song." Distributing individual hits, one-shots, loops, or stems for use as sample content (commercial or free) is not permitted, regardless of how much processing has been applied.

Yes, with one critical condition: the patch must use only Omnisphere's DSP oscillators and contain no Spectrasonics sample content. Sounds built entirely from the synthesizer side of Omnisphere (no Soundsources from the Core Library) can be sampled and distributed as audio. The same applies to sounds you create entirely from your own audio loaded into Omnisphere via User Audio.

Yes, this is encouraged. Custom .prt patch files and .mlt multi files can be freely shared, sold, or distributed. The patches reference Spectrasonics' protected Soundsources rather than embedding the audio, so the recipient still needs their own licensed copy of the host instrument to use them.

Where Spectrasonics references third-party hardware or software by name (for example, classic synth or sampler models), those names are the property of their respective trademark owners. Their appearance inside a Spectrasonics product is for identification and description only and does not imply endorsement, affiliation, or any relationship between Spectrasonics and the trademark owner.

The USB Drive Edition is the boxed version of a Spectrasonics instrument that ships with a wallet-size USB drive containing the installer, the full library, and the printed User's Guide with the serial number. Installing from the USB drive is significantly faster than downloading dozens of gigabytes of library data, and the drive is reusable as physical backup media for future installations on additional computers. ILIO ships the USB Drive Edition for all Spectrasonics instruments.

Plug the USB drive into the computer, register the included serial number to your Spectrasonics User Account, run the installer from the drive, then open the plugin in your DAW and complete the Challenge and Response authorization. The USB drive is not required after installation. Keep it in a safe place along with the printed User's Guide.

Yes. Spectrasonics installations are split into two parts: the plugin binary and the multisampled Soundsource library. During installation you can direct the heavy Steam folder (the Soundsource library) to a separate drive (typically a large external SSD) while the plugin itself installs to the standard system locations. This is the recommended setup for systems where the system drive is small but a larger drive is available for sample content.

Yes. As the registered single user of your license, you can install on multiple computers you personally own and use, including a studio desktop, a laptop, and replacement machines. Use the same USB drive on each computer, or use the Reinstall tab in your Spectrasonics User Account to access installers for additional computers. Run the Challenge and Response authorization on each machine.

Once your serial number is registered to your Spectrasonics User Account, your purchase and entitlement to installers is preserved. Registered Spectrasonics owners can access installers from the Reinstall area of their Spectrasonics User Account to reinstall on a current or future computer. Replacement USB drives may also be available as a separate item through Spectrasonics for an additional fee.
