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.

With its blend of wavetable and classic subtractive oscillators, flexible filtering and post-processing, and an extensive set of advanced modulation sources, BLEASS Megalit provides sound designers with a vast palette of timbral tints, shades, and colours to explore. Thanks to BLEASS' super-intuitive interface design, that entire sonic palette is within easy reach of even the most non-technical musicians. Megalit includes many innovations that will empower your sound designs: * Advanced wavetable oscillators with independent wavetable position and Fold controls across more than 130 wavetables. * Per-oscillator Unison mode for creating rich, layered sounds without loading additional synth instances. * Dedicated noise generator with high-pass and low-pass filters for flexible non-tonal sounds and sound components. * Resonant high-pass and low-pass filters, plus built-in Waveshaper and Bit Crusher processors for powerful sound shaping. * Four LFOs with independent timing curves and output smoothing for highly detailed modulation. * Advanced Motion Sequencer for creating complex repeating modulation patterns. * Per-patch performance controller response curves for expressive and predictable playability. * Built-in preset randomizer that generates inspiring, usable sounds at the touch of a button. * Built-in multiband upward/downward compressor for precise control over dynamics, punch, and presence. All of Megalit's parameters, settings, and controls are presented with intuitive visual feedback, so you always know exactly what the synth is doing. Despite its immense sonic capabilities, Megalit remains exceptionally CPU-efficient, leaving plenty of headroom for additional instruments, effects, or simply more instances of Megalit. BLEASS Megalit is available as an AUv3 plug-in or standalone app. Also available for Windows and Mac. More information: https://www.bleass.com/megalit
