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. 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.

“Nothing sounds quite like a Synclavier” World-class iOS synthesis has arrived! The Synclavier® II helped shape a generation of popular music and film soundtracks. Now this beast of an emotional vintage synthesizer has been incarnated on iOS using much of the core DSP code from the original and keeping the authentic red-button interface that is both deep and immediate. Not only retro, but decidedly modern: fully compatible with MPE, Ableton Link, Audiobus 3, MIDI. And the included AUv3 client can run inside of iOS DAWs such as GarageBand, NanoStudio 2, BeatMaker 3, Cubasis 3, Auria Pro. The powerful Synclavier DSP Engine affords 12 Partial Timbres, Timbre Frames, Samples, FM-Synthesis and Additive-Synthesis methodologies. It’s so easy to create playable rich string sounds, fantastic Moog esque drones, Prophet like pads, crazy FM brass noises, or Roland 808 style drum hits. It’s a sound designer’s dream and a synthesist’s wonderland. But there’s more! We’ve added a ton of stuff. The original hardware was 8-bit. With newer technology, we can pack more fidelity and more features in this already awesome synth. MPE compatibility, seven timbre “quick-change” character buttons, 16-track mixing console, crazy-good Artist Preset Libraries from world-renowned sound designers, and lots more. The Synclavier was always a versatile attention-getting instrument, but now it’s a powerhouse synth to be reckoned with! Release 1.30 features include - • iPad, iPhone and iPad Touch compatibility iOS9 or later • 96-button authentic VPK interface • AUv3 client compatibility for use within iOS DAWs • 16 original “Factory Preset Libraries” (8 banks x 8 entries) - 979 timbres • 3 “Artist Libraries” - 127 all-new timbres • Sample Library with 116 high-quality soundfiles • Audio Setup 44.1/48 kHz and sample latency controls • 16-track multi-timbral implementation with mix controls (iPad only, iPhone is mono-timbral) • Audiobus-compatible stereo output • Meticulous re-creation of the Synclavier FM sound using hardware modelling • Soundfile playback, pitch-shifting, looping, and keyboard mapping • iCloud compatibility to easily share Timbres (or via Audiobus) • iTunes file sharing for backup of user timbres and mixes • Direct expression routing for pitch bend, mod wheel, velocity and pressure • Full compatibility with MPE interfaces • Ableton Link synchronization with Repeat/Arpeggiate • 7 character buttons to quickly sculpt any timbre • Embedded “Tour” pages detailing setup and operation • Library browser for saving and calling up Timbres Synclavier DSP Engine • 12 Partial Timbres • Delay-Attack-Decay-Release envelope generators • 100 Timbre Frames per Partial • Noise Floor and Bit Depth controls • Micro-tuning controls • Dynamic and Keyboard Envelopes • Vibrato and Tremolo LFOs • Authentic re-creation of the original instrument and sounds, adjustable from 4-bit grunge to 24 bit silky smoothness. Synclavier Go! is compatible with all iPad, iPhone and iPad Touch models that can operate iOS 9.0 or later. Soundfile playback and AUv3 compatibility require iOS11 or later. The latest iOS version that is compatible with your device is recommended. The Synclavier® knob is as unique today as it was revolutionary at the time of its introduction. The knob is a rate-of-change controller; close your eyes and let your right-brain kick in to the sound design process. Forget the numbers; forget the digits; let your ears guide the process. Sound design with a touch-screen and Synclavier® knob is as different from a mouse-driven GUI as, well, Synclavier® was different than the Fairlight CMI! The Synclavier Knob is an exciting and authentic option, but is not required for Synclavier Go! since a virtual knob is provided in the app. Note to Parents: Synclavier Go! is as educational as it is historic and authentic. This app can introduce your teenager to the technical aspects of sound and sound design in a fun and informative environment.
