GForce Software impOSCar

impOSCar Image

The impOSCar is an enhanced replica of the classic British analog synth from Oxford Synthesiser Company - the OSCar. The OSCar is a much sought-after vintage mono/duophonic synthesizer that was among the first to use digitally controlled dual oscillators and offer plenty of programmability and warm analog sounds great for bass, lead, pads, efx, and so much more!

The impOSCar is a great software plug-in available as a VST instrument for Mac and PC, as well as an Audio Unit plug-in for Mac OS X. Although it's not without its glitches and bugs, it is a beautiful plug-in that accurately reproduces the original's look and lush analog sound while adding a few major enhancements of its own. This plug-in is a must have soft-synth for its ease of use and awesome sound.

Like the original it features two independent oscillators each with multiple waveforms including user waveforms - you can create your own via Programmable Additive Wave Matrix (left of the keyboard)! The original offered mono and duophonic modes, and the impOSCar adds 4-, 8-, and 16-voice modes as well! The filters have been replicated and enhanced as well, providing additional filter modes while maintaining a warm and smooth sound very much like the original. The flexible LFO section now has MIDI sync options and more too.

A new effects section offers stereo Chorus and Delay (with MIDI sync) to really warm and liven' up your sounds. The Delay has independent feedback, delay-time and wet/dry mix control for the left and right for really cool stereo delay effects! The stereo delay also features separate high and low pass filters, adjustable delay units-per-beat, and gate amount. Most of these controls are concealed under the impOSCar logo, which is easily accessed by just a single mouse-click. Additionally there are now programmable Velocity Response controls added to the keyboard (which can be shifted up and down over a 5-octave range). Additional features include a mono, duo and polyphonic arpeggiator with four modes and a portamento with six modes. Like any quality soft-synth, every control can be assigned to a MIDI controller via MIDI Learn with storable CC maps.

While the original had some patch memory storage, the impOSCar has unlimited storage, and your patches can be saved with your sequences. It ships with over 500 patches created by artists from Ultravox, S-Express, Underworld, Basement Jaxx, Terminalhead, and Republica and you can load original OSCar patches via SysEx format. Other users of the original include Hardfloor, Orbital, Ozric Tentacles, Jean-Michel Jarre, Asia, Stevie Wonder, BT, Sneaker Pimps and Keith Emerson. The impOSCar is simply the best way to get your hands on this venerable classic. BT says the impOSCar is, "quite simply, the best softsynth I have ever heard."

I'm unsure what people are saying about the impOSCar having so many bugs. I've been using this VSTi in Cubase 5 for about 2 years and it's been extremely reliable, has never crashed on me, and never overloads my CPU. I LOVE the sound of this thing (much better than any of the Arturia stuff!) I'm curious though. GeForce has had the impOSCar 2 in works for a while now and was supposed to unveil it at NAMM in 2010 but has yet to do so. They've released screen shots and everything, but no product as of yet. Anyone know what up?

Just discovered this. I've never played the real thing (nor am I likely to), so I can't comment on its 'faithfulness', but it certainly good for getting that early Underworld 'dubnobasswithmyheadman' sound. Also, it's very intuitive - all the knobs do what they say they're going to do. If you know even just a little bit about subtractive or additive synthesis, it's child's play to use. Also, just the fact that it does have additive synthesis (you can 'design' your own Userwaves by adding or removing partials) sets it apart a bit. Very nice. Plus, it's bloody loud!!!

Just tripped over this accidently. GForce is doing a blowout sale for this synth and it's the last day TODAY to get a copy for €39,-
I'm not related or anything with the company, I just thought it might be interesting for some of you...

Imposcar is one of the best sounding virtual analog soft synths, perhaps even the best sounding one. Unfortunately it's not the most stable one, the standalone version crashes frequently and the latest version VSTi does not work in Samplitude Pro 8. There hasn't been many updates, actually only one... is the company still there? I can't tell.

I somehow overlooked the impOSCcar for years but some weeks ago i rediscovered it and was amazed at the full, warm sounds. Inspired by this i made a tune. Moody and minimal but there you go
