Product Description

zZounds is an
authorized Korg dealer

You can add an internal Radias analog modeling synthesizer sound generator board (4 part multi-timbral; one timbre per Program, up to 4 Programs can be used simultaneously in Combi and Sequencer modes), with on-screen integration of all its parameters and full integration with the M3's effects, control surface and Karma functionality. An EXB- Radias Program is comprised of one timbre, with up to 4 Radias Programs able to be assigned to different timbres in Combi Mode or on separate tracks in Seq mode.

This powerful MMT-based (Multiple Modeling Technology) synth engine features dual oscillators which combine to offer analog-modeled waves, DWGS (PCM) waves, noise, ring mod and more. Waveform modulation, Variable Phase Modulation (VPM), Unison voice thickening, PWM and cross-mod expand the sonic palette.

Dual Filters can run in series, parallel, or side by side (individual for each oscillator). Filter 1 features a resonant filter design covering 24 dB low pass, 12 dB low pass plus 12 dB high and band pass, with continuously variable morphing between these states. Filter 2 offers 12dB versions of the low, high and band pass modes, plus a unique comb filter.

Two LFOs and three ADSR envelopes shape the sound and add cyclic motion to nearly any voice parameter. Three 16-step Modulation Sequencers provide discrete values to a modulation parameter that change over time, either in stepped or smooth motion, and can loop over and over.

Internal or external audio can be run through the EXB-Radias to be gated and filtered using the internal synthesis and effects. Drive adds analog warmth, Punch brings increased definition to the attack of a sound, and 12-types of Wave Shaping provides dramatic timbral shaping -- even offering virtual pickup response.

The EXB-Radias offers the same vocoder as the Radias, offering 16 bands with individual control over level and panning. Formant Motion records the formant of a sung or spoken phrase so it can be recreated anytime.

And of course, all of Karma's generative features can be used with the Radias to provide even more options, including Radias Wave-Sequencing. zZounds is an authorized dealer of Korg products.

"Korg EXB-Radias"

Sound: The sound engine that comes with this board adds more organic sounds to the M3 inventory. This board uses Virtual analog synth models which gives the possibility to create (and control) sounds that would be difficult or impossible to create with kind of synthesis. The only think I would like is to have more sounds (it came with only 128, half of the amount that comes with the Korg Radias). You can download some Combis from the Korg site that are very nice and useful as well. Feature: It does the job. I like the sounds generated by this engine. The way it integrates with the rest of the M3 is impressive as well. I like the idea of combining two different synth approaches in one workstation. You can also use Karma to add more flexibility of control to the organic sounds generated by the board. Finally you have the vocoder which is an improvement to the one that comes with the M3. It gives you the oportunity to record phrases to be played later, like the Radias or the R3. The only reason I give a 9 to it is that I would like to have more sounds. You can program them an save them on the M3´s banks. Ease of Use: The user interface merges smoothly with the M3´s OS. It is as easy as using the M3, with all the facilities that the touch screen and the intuitive OS gives to you. Also you can use the other controllers (joystick, faders, pads, ribbon controller, etc) to tweak your sounds. Quality: It´s a board. Unless it comes defective (which I really doubt) you won´t have problems with it. Value: I saw that this is often compared with some other virtual analog synths like the access virus or the prophet. I agree that the last are more advanced, but we have to understand that they are in a different price range. I´m very pleased from what I´ve got. It gives you more sound creation and song composition posibilities. Manufacturer Support: I´d never use it. The Wow Factor: Well, I can´t say I felt in love because of what I saw. Again, it is a board. You have to hear it to convince yourself that you want it. Go to youtube and hear some of the Radias demos. The sounds are different but you will get an idea of what the sound engine is able to do. There are some EXB-Radias demos as well. Overall: From the 3 options that comes for the M3, I think this is the first one you should buy. I love most of the sounds of the M3, and having this board gives me more tools to express myself using this instrument. It is an affordable option for a virtual analog synth and it works perfectly with the M3.

"Not quite a full-on VA"

Overall: Pros: Sounds like a Radias, which isn't the fat, analog super-saw machine some prefer, but I like it for what it does. Flexible signal routing capabilities, nice integration with M3 controls. Greatly expands M3's tonal possibilities. X/Y touchscreen rocks with Radias sounds. Cons: Limited real time control with the lack of knobs - yes, it's integrated into the M3's control panel, but that in itself is limiting. You can set up the M3's sliders, buttons, joystick and ribbon controller to do a lot of the real time tweaking you might otherwise use the knobs for, but you have to know what you're doing and pre-program everything. Overall, a knockout M3 expansion for a fraction of the price of a full hardware synth. The only way to make this better would be to add a RadiasR unit - but note that you don't get the tight integration with the full rack unit - it's basically a separate synth and you have limited options for mixing and blending it with the internal M3 sounds.

Style of Music: You name it, I've done it.
