Zeeon synth

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.
