From Our Research Team:

A Virtual Analog Synth for the 21st Century!

The Korg RADIAS is the keyboard that synth fanatics have been waiting for! Nobody does keyboards quite like Korg, and their RADIAS synthesizer represents a big step forward in the design and functionality. The sound module can be used independently or coupled with the dedicated keyboard allowing you to customize your RADIAS to suit your working style. It offers 256 programs based on Korg's cutting-edge MMT engine, each with up to four timbres, which you can split, layer, or run independently on separate MIDI channels. Borrowing the low-aliasing design from Korg's OASYS, each timbre has two oscillators delivering a wide variety of modulation options. The vocoder allows you to record up to 7.5 seconds of incoming information, which can be stored for instant recall. The RADIAS also includes a headset microphone for use with the vocoder, plus a free accessory shelf (keyboard version) to hold a laptop, small mixer, or a KAOSS pad. The RADIAS comes in two versions; 49-note, velocity-sensing keyboard or rackmount. Comes with editing software for Mac and PC.



Korg Radias At-a-Glance:
  • Wave Shaping, Drive, and Punch
  • Built-in Vocoder
  • Bold, Innovative Design


Wave Shaping, Drive, and Punch
Every aspect of the RADIAS voice architecture is enhanced with bold new features. The oscillators borrow the ultra low-aliasing modeling techniques from its bigger brethren OASYS, and feature Variable Phase Modulation to create complex waves. Filter 1 is continuously variable from LP to BP to HP and new treatments in between. The filters can be run in parallel, series, or individually per oscillator. The EGs feature five curves for each stage for precise articulation. Eleven types of Wave Shaping are provided, including features like modeling an electromagnetic pick-up. Drive can be added to each voice as it enters the mixer, creating effect impossible from an external effect unit. Punch delivers hard edge to the beginning of a note for added emphasis. Modulation sequencing and virtual patches extend beyond normal modulation routings.

Built-in Vocoder
More than just a "Virtual Analog" machine, the RADIAS offers an entire synthesis suite for the serious performer and sound designer. The voice structure includes four timbres per program. Each timbre is a full functioning synthesizer with dual effects, EQ, modulation sequencing and AMS routing/control. The Program provides a master effect; the two step sequencers and the arpeggiator can be assigned to any timbre, allowing complete musical ideas to be realized. The 16-band vocoder is instantly accessible. The level and pan of each band can be set individually. Formant Motion records over 7 seconds of incoming formant data that can be used to create vocoder effects without any audio input. Sixteen sets of Formant Motion data can be saved and used in sound creation.

Bold, Innovative Design
The "Future/Retro" design pays homage to famous synths of the past (the tilt-up panel is reminiscent of the original Mini-Moog) yet the illuminated knobs, pad keys, and blue-on-black display are definitely modern, and provides excellent visibility. Sliding the panel to one side allows the accessory shelf to be installed, accommodating a laptop, KAOSS Pad, small mixer, etc. A live front panel, LCD screen, and illuminated controls provide an intuitive, easy-to-use interface in any environment! The RADIAS features two individual outputs, in addition to the main Left/Right outputs. To access the vocoder, envelope follower, and other processing, two audio inputs are provided, plus a special input jack for the headset vocoder mic. USB connects the RADIAS directly to a computer, with no MIDI interface required. Even with all this sonic firepower, it's easy to tame this audio arsenal. Template data is provided as starting points to help in your programming efforts, greatly speeding up the sound creation process. Four timbres can be combined into a single program. These can be zoned on a single channel, or operate on independent MIDI channels for true multi-timbral operation. Any timbre can be set to a drum kit. Any timbre can be assigned to played by a step sequencer or by the arpeggiator. The on/off status and gate time, can be set for each step, and the swing amount and octave range can also be specified.

Korg RADIAS Synthesizer Features:
  • Two oscillators per timbre, which share the low-aliasing design of Korg's OASYS
  • Modeled analog, formant and Korg's classic DWGS waveforms, PCM playback, as well as ring modulation and sync
  • Dual multimode filters, three envelopes, two LFOs, three modulation sequencers Six virtual patches (for freely connecting any of 11 modulation sources to any of 15 destinations)
  • 2-band EQ, Drive, 11 types of Wave Shaping
  • Punch parameter emphasizes the attack portion of the sound
  • Each Program contains an arpeggiator with six pattern types and two Step Sequencers
  • 16-band vocoder section, each with level and pan controls
  • Formant Motion function records up to 7.5 seconds of incoming formant information per Program so users can recreate vocoder effects even when no microphone is present
  • Headset microphone included
  • Two insert effects for each timbre, plus a program-wide master effect.
  • 30 included effects types range from delay, chorus and reverb, to compressor and talking modulator

Simply Amazing

by Scott S. from PA
July 13, 2010
Music Background: Semi-Pro Musician
I also own a Korg M3 and was considering the Radias EXB, but when I saw all the controls and features of this unit, I bought it instead. Really wasn't sure what to expect, but when it arrived from Swe... read more [+]etwater, I spent a long time playing and tweaking sounds.

The sequencer and arps really add to the "wow" factor of this synth... (something you wouldn't have when adding the EXB to the M3). You get instant inspiration right out of the box. And--If you enjoy programming synthesizers you'll love all the knobs and buttons.

The Radias is more than a "straight synth" though, with some superb organs, EPs and other sounds you may not expect. Definitely 5 stars. close [-]

I love this synth. You are able to get warm analog type sounds along with great digital tones. The multi filter is wonderful. Just having all the knobs available to tweek is a big plus.

Great Module

Music Background: ~15 yr music hobbyist
I'm not too picky when it comes to gear. I just simply wan't to get my $$$ worth. I did with this. I'm sure I won't get bored with this guy for a long long time. Couples nicely with an EMX and wor... read more [+]ks well in a midi hardware based system. Sounds simply awesome. One thing I will note. I've had terrible luck with integrating a PC into my studio. This unit is no exception. I had tried, and failed, a half dozen times to get the PC controller software working for the RADIAS-R. I have a MicroX, and the RADIAS controller software will recognize it, but not the RADIAS. I've given up for now. I blame the PC, though it should work if the instructions are followed properly.... I prefer to work directly on the module anyway so it doesn't bother me much. close [-]

Sweetwater Advice

Carson McClain
You can never go wrong with a Korg synth that has a ton of knobs and a ton of sounds. thought the RADIAS was just a newer version of the Korg MS2000, but boy was I wrong: vocoder, built-in effects, tons of great sounding editable presets. It's on with this synth! Yet another amazing product from Korg.
Mike Hammond
Awesome solution for various electronic musicians, but especially anyone that wants one simple solution for techno, trance, synth pop, hip-hop, and such. Being multi-timbral, the Radias provides your drums, bass line, lead and chords all at once. Of course, there there a zillion ways to tweak your sounds in real time!
