    Holy wow. This is a gorgeous emulator of a weird and wonderful synthesizer. I discovered this while browsing through the Trunk Records online catalogue, and now it’s my favorite app by a lot. Made with love by and for music nerds.

    From the start I was excited to have access to such an incredibly rare synthesizer experience as the hardware version of this model is next to impossible to find even in a synth Mueseum! But the roster of artist who have used this is as long and thick as an old phone book! The icing on the cake is apesoft and especially James Edward Cosby continuing to support and build upon this synth with updates and presets that customize and help any sound designer and synth musicians from newbie analog programmers to the geniuses that understand the deep complexity of the real wires and patches of CV and modulation “electronic goodies” that make this such a special secret weapon to any kit! Roger Waters was the artist famous for saying “there are lots of electronic goodies made available for us to be bothered with....and we will be bothered!” From the documentary “Pink Floyd - Live at Pompeii” when Roger was positively inspired creatively when he says ‘bothered’ in a most noble way ....with parts of the film showcasing Roger programming and playing this very synth in what would become “The Darkside of the Moon” album of all time! When I saw this strange synth I never realized how rare it was but since technology has made it possible with programming and development by apesoft and James Edward Cosby (Jim Cosby)! This is after many years of surprise and intrigue oh and much joy in sound design playing this instrument that I finally wrote a good review in honor of yet another addition in “captivity” to blow my mind yet again! So this review is well past due and much deserved! Bravo! Bravo! And Bravo, indeed!

    Title says it all. Makes wanna mill some nice spruce sides to affix to my iPad. This really,to me, makes any and every reason to own iPads. Really sounds monstrous through some choice plug ins via AUM then into a good P A. Thanks for the killer app and let’s get going on the CS-80 emulator!

iVCS3 Official EMS VCS3 emulator 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. Description 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. Keyboards controller DK1 keyboard controller 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.…
