Zeeon synth vs FabFilter Twin 3

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.

Since its first release in 2005, FabFilter Twin has been famous for its filter quality and oscillator sound. FabFilter Twin 3 expands and improves on its predecessors in every area, including a complete redesign of the GUI and workflow, more and better oscillators and filters, a radically powered-up modulation system, an all-new FX section, and much more. Sonically versatile, supremely intuitive, and spectacularly ‘analog’, Twin 3 is a dream instrument for creating synth sounds of all kinds, from basses, leads, and pads to plucks, drums, effects, and beyond. The Twin 3 app lets you play via the on-screen keyboard or a MIDI keyboard connected to your iPad. To use Twin 3 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Twin 3 will appear in the list of Audio Unit extensions for instrument plug-ins in the host app. Key features: - Virtual analog synth featuring four flexible oscillators, four filters, six FX modules, and a vast modulation system with a wealth of flexible source signal generators, drag and drop source/target routing, and no limit to the number of modulation assignments that can be made - Fully redesigned, greatly simplified interface with easier workflow - Completely overhauled modulation system with redesigned modulation sources, and floating slot and FX panels - All-new FX section, housing Reverb, Delay, Chorus, Phaser, Drive, and Compressor modules - Arpeggiator with Groove/Legato controls, note order, latch options, and more - Full-featured preset browser, with tags, favorites, and search and filter functions, and new factory preset library - Per Oscillator polyphony mode: each incoming note triggers a different oscillator - Bell, Shelf, and Notch vintage-style EQ filter shapes - 6dB/octave filter slope option - Modulatable filter Cutoff/Peak Offset knobs knobs, for adjusting all filters at once - High Quality mode — 4x oversampling - Transient mode turns Envelope Followers into transient detectors - Curve adjustment handles for EG Attack, Decay, and Release stages - Slider mode (vertical-only operation) and Range setting (toggles between bipolar and unipolar behavior) for XY controllers - Hide all modulation sources except for XY controllers and Sliders at a click - Native sustain pedal support - Even better oscillator and filter sound quality, with analog-modelled drift - Maximum number of voices doubled from 32 to 64 - Lower minimum Envelope Generator Attack, Decay, and Release times - Maximum number of XY controllers/Sliders increased to six - Envelope Generator Threshold, XLFO Balance, and Frequency Offset made available as modulation targets - Modulation sources can be renamed - Maximum number of modulation slots increased to 100 - Legato mode for MIDI-triggered XLFO - Range options added to MIDI Sources: Negative (-1 to 0), Centered (-1 to 1), and Positive (0 to 1) - Carefully designed and curated factory presets, plus the ability to save your own presets - Undo/redo and A/B comparison "FabFilter Twin is one of the best virtual analogues we've heard so far, and at this price point it's well worth the investment!" — Computer Music "Once I found FabFilter Twin, I immediately noticed how great it works and how amazing it sounds!" — George Morel
