ApeSoft has released iVCS3 for the iPad and is describing it as an official EMS VCS3 emulator. We don't have any details of the app but here's a history of the original...
The VCS3 was created in 1969 by Peter Zinovieff's EMS company. The electronics were largely designed by David Cockerell and the machine's distinctive visual appearance was the work of electronic composer Tristram Cary. The VCS3 was more or less the first portable commercially available synthesizer--portable in the sense that the VCS 3 was housed entirely in a small, wooden case.
The VCS3 was quite popular among progressive rock bands and was used on recordings by The Alan Parsons Project, Jean Michel Jarre, Hawkwind, Brian Eno (with Roxy Music), King Crimson, The Who, Gong, and Pink Floyd, among many others. Well-known examples of its use are on The Who track "Won't Get Fooled Again" (as an external sound processor, in this case with Pete Townshend running the signal of a Lowrey Organ through the VCS3's filter and low frequency oscillators) on Who's Next. Pink Floyd's "On the Run" (from The Dark Side of the Moon) made use of its oscillators, filter and noise generator, as well as the sequencer. Their song Welcome to the Machine also used the VCS3. The bassy throb at the beginning of the recording formed the foundation of the song, with the other parts being recorded in response. The VCS3 was also a staple at the BBC's Radiophonic Workshop, and was a regular (and most frightening) sound generator for the Dr Who TV series. Many fo the monsters and atmoshere;s created for the show came directly from the VCS3.
The VCS3 has three oscillators (in reality, the first 2 oscillators are normal oscillators and the 3rd an LFO or Low Frequency Oscillator), a noise generator, two input amplifiers, a ring modulator, a 18dB/octave (pre-1974) or 24dB/octave (after 1974) voltage controlled low pass filter (VCF), a trapezoid envelope generator, joy-stick controller, voltage controlled spring reverb unit and 2 stereo output amplifiers. Unlike most modular synthesizer systems which use cables to link components together, the VCS3 uses a distinctive patch board matrix into which pins are inserted in order to connect its components together.
Although the VCS3 is often used for generating sound effects due to lack of built-in keyboard, there were external keyboard controllers for melodic play. The DK1 in 1969 was an early velocity sensitive monophonic keyboard for VCS3 with an extra VCO and VCA. Later it was extended for duophonic play, as DK2, in 1972. Also in 1972, Synthi AKS was released, and its digital sequencer with a touch-sensitive flat keyboard, KS sequencer, and its mechanical keyboard version, DKS, were also released.
Pricing and Availability:
This is a GREAT app. Tons of Radiophonic sonic capabilities, lots of configuration settings going on behind the scenes, MIDI mapping ability, sampling & external input ability, X-Y pad, simply brilliant. The only thing missing in my humble opinion is the replication of the attack button at the bottom of the screen (maybe latchable), so I can twiddle knobs without having to scroll up and down to get to it. Sure, you CAN press the button on screen and scroll around while keeping your finger held down in the place where the Attack button was, but thats kinda distracting. Add this little feature (and possibly a Synthi A skin) and I will have second thoughts about going ahead and building that clone I've been looking into doing.

Thanks Darren! Didn't notice that one. Thats a great little feature. Liking this little app a lot. Much more hands-on than the one I have from Xils Lab.

You lazy b*stard—you lifted the copy whole cloth from Wikipedia—WITHOUT ATTRIBUTION. Did you think no one would notice?
