Excellent softsynth ! The SEM emulation sounds superb in all regards; it's the only SEM emulation with proper hardsync that I know of. A third oscillator is a fabulous addition, offering accurate PWM, FM, and filter modulation at audio frequencies. Love it ! Also nice is the presence of the Oberheim voice allocation system, not available elsewhere. Highly recommended.

Really wonderful virtual synth. Fattest sound I have heard from any synth in 30 years - analog or digital, physical or virtual. Expensive for what it is and Mac only no PC version which is not acceptable in this day and age. I expect a windows version and sale pricing in the future or this will be a business failure. But the sound quality is really well done, you can tell the G-Force folks poured a lot of heart and soul into this effort. PluginGuru also unified the patches which make the whole thing just ridiculously awesome. Warning - don't try the demo unless you are prepared to part with @ $200.

Phantastic sound, not easy to edit but good patches. Good for drum and bass. No tuning possible to 432 hertz f.e.

I am most grateful that G-Force's upgrade mechanism to their new Oddity 2 leaves the original Oddity untouched and in place. The new 2 is definitely a wonderful expansion on the original concept, supplying polyphony, multiple filter choices and other capabilities that suggest a truly classic keyboard ARP might well have produced if it had stayed in business a couple years longer. But the original lean, mean machine that G-Force developed over a decade ago hardly suffers in comparison. In fact, contrasting the two only reminds what a potent monophonic/duophonic synth the original remains.

More that any specific feature, G-Force captured the Mojo of the ARP Odyssey better than any other software emulation of any other specific vintage synth than I'm aware of. The thing simply behave like an Odyssey, from the wonderful interaction of the sliders and all that duophonic/RingMod/S&H goodness. It's blatantly obvious that this was a labor of love.

SOUND: This doesn't quite sound like any Odyssey I've had my hands on, but for a very good reason. The filter that was modeled is a fully working 4075. That's a modification that was not standard with the original production run. When ARP agreed to remove the 24 db lowpass 4035, that Moog insisted was too similar to their own classic ladder, an engineering error produced a somewhat hobbled filter, that was perhaps closer to their original 12db 4023. It wasn't until later on, post run, where a simple repair allowed the 4075 to operate at its intended spec. And it is this full spec 4075 that the Oddity has been programmed to recreate. The new 2 now allows you the choice of substituting the juicier 4035 or a smoother (Oberheimier?), less nasal version of the 4023, but that full spec 4075 is a great, full bodied thing.

GUI: The classic black and gold is my favorite Odyssey look. Granted, it doesn't sit as big on the screen as I would like (neither does the 2) and the little letters are damn near impossible to read without squinting. But this is an Odyssey, probably the most right-brained synth you can imagine. It practically no time you get a handle on moving those sliders around without having to bother reading anything. And the magical way that the slightest adjustment dials in such unsuspected wondrous sounds remains a true joy. Less is more on this thing.

CPU: Their are some new spot on Minimoog emulations out there that take advantage of "zero-delay-feedback-filters", that chew up CPU for lunch, though computers are getting more and more capable of handling bigger loads. And even the new 2 can put a slightly aging laptop into the red if you're using a lot of voices, especially if you're recording up in the 88.2, 96 range. The original Oddity barely moves the dial. And there's no doubt that it sounds ARPy to all get out. An elegant weapon that won't let you down in the mix.

PATCH CHART: Finally, I find the original an ideal partner for my vintage black and gold. When I stumble onto a pleasing sound on the hardware, it's pretty much a snap to quickly recreate it on the software and save it. I can either record it as is on the Oddity, or bring it up and recreate it on the Odyssey, depending on the situation. Very handy, actually.

So, as this software turns over to a well deserved update, this review is more a note of appreciation and admiration for a product well done from the get go whose excellence remains to defy the usual short electronics lifespan.

I bought the impOSCar in the last deal that GForce was running for 3 weeks. Even if you didn't had the opportunity to get in in that period, I do believe that this synthesizer is a must-have for everyone that is looking for a synthesizer full of character. It's always good to remember that this plug-in was released 6-7 years ago and I really wished I would've discovered it earlier.

User Interface
The interface is based on the original hardware and you can get your head around it pretty easy. It's a single page interface, while you have to turn a knob to edit the user waves or enter the MIDI learn function of impOSCar. It's straight forward and fun to use.

The best part of impOSCar got to be the lovely sound. This synthesizer never sounds bad and truly shines, thanks to his own and unique character.

It's still considered one of the best analogue sounding synthesizers out, while the original OSCar was mainly digital, beside the filters. I don't really care for those topics and I probably will never touch a real OSCar since there are only like 2.000 pieces made. The only thing that matters is how it sounds and I do think that impOSCar is one of the best sounding plug-ins ever made. On top of that its very light on the CPU. 1-2% per instance on a little dated dual core system.

The additive feature adds another flavour to impOSCar and gives it a wider range of sounds than any average subtractive synthesizer. The different LFO sync rates, like internal, clock or MIDI are useful to make some really nice modulations on different or unusual tempos. I really like slow filter modulations.

You can imagine the filter separation to be like 2 filters but it's hard to describe, how many different shapes you can get out of this feature, together with adding some nice drive to the filters too.

The 2 effects, chorus and delay, can sweeten up a sound in no time.

PDF in 6 different languages to get you started, while I still think you can just dive into this synthesizer to explore it the best.

500 presets in the factory of impOSCar with some sounds made by a guy that made sounds for Jean Michel Jarre, if I'm correct. Plenty of others to download from the GForce site and KVR's Bank & Patches section. I do have to say that I like the factory sounds a lot, but impOSCar is just that much fun to play with that you always will find yourself tweaking it.

Customer Support
I purchased it via PayPal which was obviously supported by the GForce shop, but after some e-mails and a manual payment to their PayPal I had my impOSCar waiting for me in my account. I also read that some people had issues with the installer under Win7 64bit and Dave (from GForce) did uploaded the single files so they could pass the installer, so the support really seems to be decent.

Value For Money
Like I said, I did get in in a deal period and so it was one of the best purchases ever, but even the original price is still a real bargain, considering you like the flavour of impOSCar.

Not one single crash in 3 weeks.


A truly sweet synthesizer with some sweet filters and character. It's just that much fun to play around with it and get lost for hours and in the same time the simplicity is raising creativity, becoming more and more a part of my sound and productions.

The impOSCar is a landmark on VSTi synths, and probably the one closest do delivering the "analog sound" most of us seek. However, it's not exactly an analog emulation per se, because the original OSCar had digital oscillators.

The basic sound is very pure and warm, rich in harmonics and very clean, but under the hood we'll find that the oscillators also support additive synthesis - something you don't get on your everyday VSTi. This is very useful for harsh sounds, synthetic bells, experimental noise and for advanced sound design. The thing with the oscillators is that they have that full-range-but-not-icepicky sound so rare in synths today - it is a colour of its own, like Eddie Van Halen used to say, a "brown" sound...

The next stop is the "Drive" feature - something I abuse on my day-to-day music making. But, just like the original, it doesn't distort the sound - it is merely an overdrive to change the harmonic response. Very useful for thick basses and leads, and the reason I don't care about the lack of an "Unisson" option.

The filters are also at an league of its own. The Separation knob is unique to this design, and splits your filter in two, giving you more control over ressonance. The basic 24db/oct lowpass is turned with two 12db/oct filters, for example . You can also crank the Q knob and use Separation to turn a bandpass (or lowpass+bandpass, or whatever) into a very rich formant filter.

Other than that, the interface is very easy to use after you get a grasp of it. I'd reccoment this software to anyone trying to learn analog synthesis, because everything is at your face, and harder features are very inviting to experimentation. The patch library contains a large number of quality sounds, and the manual explains the harder functions in detail.

Summing these three main features I must say that, in my opinion, this is the best sounding VSTi ever written.

OK I downloaded the demo of this badboy 2 years ago when I was 1st getting into VST and played around with it, monitoring via headphones and was blown away! (This thing sounds like my vintage hardware synth). I was recently looking to add an other gem to my arsenal and again came across its great ratings and downloaded the demo again and again was blown away (this time monitoring through some M-Audio BX5a's). I bit the bullet and bought it.

UI: One of the great things about this synth for me is its simplicity. All the parameters are on one page (what you see is what you get). About 90% of all the parameter are controllable by CC# too, which can be "revealed" with the turn of a knob. Perfect little size with the ability to "hide" the keyboard too. I suggest you plug in, map some cc#'s to your midi knobs and have at it. You're pretty much up and running out of the box.

Sound: This is where this BEAST shines. The filter is quite simply amazing and capable of the nastiest lows and most piercing highs. They've done a great job of making this thing sound authentic. So much so that I checked my monitors at one point because it sounded as if I may have ripped them. After fiddling around with the "drive" knob on the UI I soon found out that this "rusty" sort of "broken tube" sound slowly disappeared as I adjusted the amount. It's sound quality is outstanding. Dont take my word for it...or for that matter the words from the all the famous folks who use it (Trent Reznor, Crystal Method, BT, etc). Do yourself a favor and download the demo.

Features: Like I said its simplicity is one of my favorite things about this synth but its got some cool little bells and whistles like "user wave creation" and a decent set of quality basic effects.

Presets: 500+ quality presets. You cant beat that.

Value For Money: This is one of THE BEST value purchases I've made. Its overall quality far outweighs its price. Very reasonable indeed.

Stability: Also a TOP selling point to me. It works like a charm in Ableton. Its CPU use is GREAT for the sound that it produces (i've never seen it go above 4% with one instance-I run a Conroe 2.13 over clocked to 2.8G). Its never crashed or given any weird pops/clicks/graphical errors, etc.

So all in all...Im very glad I made this purchase. It has stood the test of time. Check the forum, the recent 2007 reviews, the countless "pro" opinions on this synth...its just the shit. Its capable of lots of bread and butter and quite capable of creating unique sounds.

From soaring poly-pads to squelching, distorted hellish sounds it packs POWER. You can almost feel the voltage. This f*cker SCREAMS!!!

Wow. When I read the review for this thing, I thought, "No way this 4-year old soft synth could be that good!" Oh, how I was wrong. Never before I received such joy just from playing a synth. I don't even need to put it in a song. Just open it up, and rock some chords on this thing, and before I know it, I am smiling like a baby. It is absolutely breathtaking. It can do everything, although I find it best for keys and pads, rather than basses. It can do good basses, but its abilities are somewhat wasted. Like driving a Ferari to the grocery store.

It can be a little confusing at first, but you wouldn't believe how well the manual clears it up. Without the manual, I would probably give it a 6.

I can't even do it justice with words. Just try the demo, and then when it starts making horrendous, disturbing noises (the copy protection on the demo slowly increases the noise level in the background until it becomes deafening), but it. Best beal on the planet.

It's not Absynth or Massive, but I am not going to dock any points for not cramming it full of features. It has what it needs, and uses it all well. The filters are... geez, I'm speechless just thinking about it.

As mentioned before, the manual clears up any questions you may have about the UI, so I give it a 10.

I am not much of a preset user, but it does come with a lot, and they show off its extreme might very well. Also, in the newest update (not in the demo) there is a much better preset browser built into it, so that is very nice.

Customer Support:
I am giving a 10 for the addition of the preset browser. It was something that obviously a lot of people wanted, so the updated the synth to have one. Plus, they seem to be owned by M-Audio now, so you can't go wrong there (I think).

Value For Money:
If there was an infinity symbol available instead of a 10, I would give it infinity. If you buy one synth, buy this one.

Has not crashed yet. I did have some weird issues running multiple instances, but as far as I can tell, I fixed that when I updated to the latest version.
