Zeeon is a virtual-analog synthesizer built on a deeply detailed circuit-modeling engine. We’ve studied classic and modern analog synths to uncover what gives them their unmistakable character and recreated that essence with precision. The result is a unique instrument that delivers the warmth, movement, and organic depth of true hardware. While many emulations sound flat, Zeeon breathes. Every note is alive, with tight lows and shimmering highs. All audio and modulation are processed at 176 kHz (4× oversampling) for uncompromised quality across the entire spectrum. “Desktop-class sound engine … fidelity of this analog emulation goes beyond everything else on iOS.” – App Store review Features • Audio Unit v3 and standalone application with a simple polyphonic step sequencer • Powerful modulation matrix offering self-modulation and cross-layer modulation, 8 modulation slots, 17 signal sources and 41 targets available, both from modulation modules and audio signal path. This takes Zeeon into semi-modular territory. Imagine oscillator waveform, panning, filter cutoff, resonance or LP-HP mode modulated by oscillators or another layer! • 2 oscillators with continuously variable waveforms, hard-sync and sub-oscillator. Carefully simulated analog drift and PSU influence. • Filter: 3 models available: Transistor ladder low pass, OTA cascade low pass and State Variable Filter with continuously variable LP-HP + BP mode. • 2 low frequency oscillators and envelope generators per voice. • Overdrive: diode clipper, transistor saturation, wave folder, pre and post filter. • Up to 2 layers per voice. Layers can modulate each other. • Effects unit: Circuit modelled BBD chorus, bass booster, zero-delay Phaser, Stereo delay and Reverb. • 280 presets and Tutorials bank. 3 additional banks available as IAPs. Full manual and audio demos available at the BeepStreet website.

“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.
