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.

A new and unique Arpeggiator by BLEASS & Canblaster. Use it as a MIDI FX to control any synth or as an AUv3 Instrument thanks to its built-in FM Synth! BLEASS Arpeggiator takes the inspirationally melodic power of a classic synth arpeggiator and supercharges it with modern features demanded by today’s musicians. Developed in collaboration with top French producer Canblaster, BLEASS Arpeggiator’s capabilities extend far beyond the clichéd up-and-down monophonic patterns of an old-school synth arpeggiator, with polyrhythms, polyphony, and a large collection of highly configurable arpeggio patterns built in. The focus of BLEASS Arpeggiator is creativity and experimentation. The plugin’s hands-on user interface is as intuitive and spontaneous to use as a classic subtractive synth, so varying and adapting arpeggios on-the-fly is an easy, fun and organic experience. The plugin recognises incoming performance controllers, and includes a pair of XY pads, a pair of advanced LFOs and BLEASS’ signature Motion Sequencer. These can modulate the arpeggiator’s parameters, unlocking a deep level of creativity that is simply not available from modern step-sequencer-style arpeggiators. BLEASS Arpeggiator also offers a built-in sound generator. This is a cut-down yet great-sounding FM synth that’s perfect for creating bright, sweet and punchy sounds that can work well with an arpeggio line. You can of course use BLEASS Arpeggiator with any other synth too, with each instance of the plugin creating its own MIDI source that can be routed to any instrument within your project. More information, technical specifications and tutorials available on https://www.bleass.com/arpeggiator BLEASS Arpeggiator is available as an AUv3 plugin or standalone App. BLEASS Arpeggiator is also available for Windows, and macOS.
