I really see Radias as an instrument that I will never outgrow. I do not believe in obsolescence and as such I believe that Radias will always be an integral part of my music making experiences. If the Radias was stolen and I had to WALK to get another, no matter the distance, I would buy another immediately.

The Korg Radias seduces you; she is alive. There is something very inviting about this instrument. Radias takes a lot of work to get to know. At first there is a bit of confusion as there are a dizzying number of qualities that both entice you and can induce some trepidation as well. But when you become familiar with her the rewards are simply amazing. Radias fits so well with mt current rig. At present in addition to Radias I am making music with Kronos, Fantom X8, XV-88, Kurzweil PC3, JP-8000, and SH-32. Radias fits in perfectly and it is a blast to experiment and MIDI it to the other instruments. I have found that the coolest combination is the PC3 and Radias combination. When you combine the insane depth of a Kurzweil with the semi-modular approach of Radias there really isn't any sound that you cannot create. But this review is about the Radias as it is and so I'll focus there. The Radias possesses character and can be as gentle as a kitten and as ferocious as a tiger. As with any synth I would offer that presets only serve as a jumping off point to more complex soundscapes and in this the Radias delivers a way to create a palette read more that is as varied as any serious musician would desire. Rockers take note that while the presets and the vocoder seem to make Radias more appealing to hip-hop, techno, trance, and other forms of dance, Radias is a GREAT synth for all sub-genres of rock from experimental stuff pioneered by the Beatles to the icy aggressiveness of Scandinavian metal and everything in between. Radias invites experimentation and believe me there is far more under the hood of this instrument than you would suspect. In fact, experimentation is far more rewarding than reading the manual; this synth really is made for people who want to think outside of the box and create soundscapes that have yet to be heard. People who play ROMplers such as Yamaha take note: Radias is a synthesizer so do not expect stunning Steinways or be able to produce a Stradivarius that would make Perlmnann green with envy. While there are some PCM samples onboard, the real strength in this instrument lies in its stunning ability to create extremely complex synthetic textures. Modulation possibilities abound as well, the filters are extremely flexible, and you really can approximate and in many cases completely capture those vintage Prophets, Oberheims, Moogs, and Arps in addition to creating your own living patches. This is simply a masterpiece by Korg and I would strongly urge anyone interested in experimenting with a very powerful means of sound creation to explore Radias. The price to power to ratio is simply among the best in the industry.

I gave Radias a "9" because I do not believe that there IS a best or a "10" as far as musical instruments. In terms of accessories Radias comes with a nifty sweet gooseneck mic for vocoding purposes and the first thing you will want to do is experiment with this. In a sense, you should really think about vocoding as a way to move beyond just vocal creations. The vocal input really is a carrier that is modulated by the synth engine itself. I can only imagine what a guitarist or bassist could do with Radias in conjunction with the vocoder.

Ease of Use
Like any high end VA, Radias has a crazy number of buttons and knobs and many of these buttons and knobs are multifunctional. The interface IS a bit cluittered but considering the amount of real time control you have over this instrument and the amount of parameters you have available for patch creation, I am thankful that Korg went this route as opposed to the ROMpler approach of menu driven screens. There IS a learning curve to this instrument but that learning curve constantly rewards you and many times you will find those wonderful serendipitous moments when you tweak just one knob and you have created a stunning patch that inspires you to compose! The manual is really a reference and is not much help. Note to the industry: you should consider paying your writers a little more so that manuals are more logically arranged and you should allow for some tutorials. Many people need a sort of guide at first to gently ease in to complex instruments and the addition of tutorials would actually increase sales.

Radias is ROCK solid and I have no worries about taking this beast on the road and in any type of venue. The knobs have a tight feel which is a GOOD thing because precision is so very important in a synth. This is a reliable instrument and I have no worries about possible failure in the unit. I should qualify by stating that Kronos obviously does everything Radias does and more, but that is to be expected from an instrument made in 2012 - the Radias was released in 2006. But, I do not rely on Kronos to fill in for Radias. Road warriors need not worry about the durability of Radias. When turned off it DOES look like something that belongs in a NASA setting or a high tech medical office but turn it on and it comes alive and looks like a musical instrument in the Star Trek era.

As I have stated, the price to power ratio in Radias is simply amazing and in these tight economic times the adage "bang for the buck" applies in spades here.

Manufacturer Support
I had to contact Korg about a question I had regarding Kronos so I can at least speak to my experience with their customer support. They are helpful and quite patient and will direct you quickly to the technician who specializes in specific areas of the instrument's architecture. However, if your cell phone drops a call you have to go through the queue; Korg does not allow you to give your phone number for an immediate call back. I think that this is not the best of practices and I would hope that Korg would adopt a more friendly attitude in this regard.

The Wow Factor
Turned off, the Radias has an understated laboratory look to it. But there is a nice feel to its aesthetic with its silver front panel and black knobs. Turned on, Radias feels like a Pink Floyd light show! What drew me to Radias was its plethora of real time controls that seem to say, "come and play; let's see what vistas we can discover today!"
