Complete Realtime Audio Control for Mac and PC

VariOS is an open-ended hardware/software system that allows musicians to build audio-based tracks with the same flexibility as MIDI. All processing is handled by the VariOS module, which is controlled using bundled software. The first software bundle is V-Producer for VariOS. This software lets musicians manipulate a sample's pitch, time and formant, add effects and even build complete arrangements while keeping the music flowing and without CPU drain. And since the VariOS module can be updated, the system can take on entirely new functions in the future.

The Power of VariPhrase in Your PC

Imagine having a software program that allows you to build complete audio-based productions in real time without draining your computer's processor. That's the idea behind VariOS. This open-architecture system combines intuitive V-Producer for VariOS software with a 1U hardware module to create the most powerful audio production system ever conceived. Create complete 6-part audio arrangements while freely manipulating pitch, time and formant. VariOS also comes with separate reverb, chorus and multi-effects so you can process and mix your samples in a plug-in like environment. A simple USB connection is all it takes to be up and running.

Easy Audio Encoding and Arranging

Building a song with VariOS is a simple process. First, browse your computer hard drive for .WAV and AIFF files. V-Producer can then quickly and automatically batch encode the data and transfer it via USB to the module. Once encoded and transferred, you can arrange tracks in V-Producer using simple drag-and-drop commands. Best of all, any audio file can be made to work with another, since VariPhrase permits independent manipulation of pitch, time and formant without unwanted artifacts.

Twist Your Loops with GrooveScope

V-Producer's GrooveScope window takes reconstructing audio loops to new extremes. First, GrooveScope analyzes the audio and time-slices it into separate events. But here's where things get really interesting: These events can not only be re-arranged to create new loops, but each event's pitch and time can be manipulated graphically without altering the original sound quality. All editing is non-destructive, so you're free to experiment as much as you please—all in real time. And if you prefer tweaking with knobs rather than a mouse, just twist the VariOS module's dedicated controls while scanning the audio loop, and V-Producer will faithfully capture all your moves.

PhraseScope: The Ultimate Vocal Tool

V-Producer's PhraseScope window separates the melody from the rest of the phrase, allowing users to re-construct a new melody or add harmonies graphically, or by playing in notes from a MIDI keyboard. Using PhraseScope, you can take an existing vocal phrase or melodic instrument phrase and change the actual notes, phrasing and vocal gender without unwanted artifacts. Need some quick background vocals? Just play in the harmonies from a keyboard. You can even tweak pitch, time and formant from the VariOS module's knobs. And like GrooveScope, all edits are done in real time and non-destructively.

Integrates with Your Favorite DAW

While VariOS gives you the power to create complete audio-based compositions without any additional hardware or software, it's nice to know you've got options. That's why V-Producer includes the ability to sync to MIDI clock and MTC, enabling it to run smoothly alongside other sequencing programs like Logic, Performer and Cubase. Arrangements can also be exported as Standard MIDI Files (Format 1), and encoded audio files—or an entire arrangement—can be saved as stereo .WAV/AIFF files for further manipulation in other DAW programs.

Convenient Stand-Alone Operation

Want to take your VariOS rig on the road? Simply load the samples to the VariOS module using USB, edit them with V-Producer and then save them to the onboard flash memory or PC card. Now you can take the VariOS module out on the road for use as a 6-part multitimbral sound module loaded with your VariPhrase-processed sounds, while still being able to freely manipulate pitch, time and formant using the knobs or MIDI commands.

An Open-Ended System

One of the best reasons to own VariOS is that its functionality is not limited to audio manipulation and construction. Since the module itself is simply a dedicated processor, VariOS can become an entirely new product just by updating the firmware.
Delivering on the promise of an Open System, Roland is proud to offer two instruments for VariOS: the VariOS-8 Analog Modeling Synth and VariOS 303 Analog Modeling Bass Synth. VariOS firmware updates can be downloaded free of charge, and then loaded into the VariOS module via USB. Once the firmware is loaded, simply launch the new control software and turn your VariOS module into two exciting modeling synths.

Known for their warm rich sound, Roland's analog polysynths have been used by countless musicians. And now these sounds can be yours in the new VariOS-8 without draining your CPU!

VariOS 303
Designed exclusively for VariOS, the VariOS 303 is an analog-modeled bass synth reminiscent of Roland's vintage TB-303. It looks, feels, and sounds like the legend, but provides additional features that make programming easier than ever before.

V-Card Expansion

Add powerful new capability to your VariOS with Roland's innovative V-Cards (optional). Currently in the lineup:

VC-1 "D-50 for V-Synth/VariOS"
This card transforms the VariOS into Roland's legendary D-50 L/A synthesizer. Simply insert the card, power up, and you'll be transported back to the year 1987, when Roland's D-50 ruled supreme!
Editor software "UniQuest VC-1" is included (Win/Mac).

VC-2 "Vocal Designer"
The second offering in the V-Card Series turns the VariOS into an advanced vocal-modeling processor from legacy vocoders to massive choir models with expression never before achieved in conventional voice-processing algorithms. Make your audio sing, howl, and growl like never before.
