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.

This is my first iOS synth and I love it! Designing sounds on it and playing them is so much fun and easy. It’s can be deep but it’s not mind boggling, I know basic synth parameters but I’m not great and thus was easy to pick up and it’s really teaching me a lot and most importantly it sounds fantastic.After having used it for a little while now I find that I really like just sitting down for 5-10 minutes and programming a patch that I like which often leads me to find a chordal or melodic idea I really like. I could open up GarageBand and start a new project but that sort of kills the fun and spontaneity of quickly making a patch and finding something cool, recording it and getting back to work or whatever I was doing. I think that’s part of what the iPad was made for. I’m trying to find a way to do that, the easiest way I can see is through IAA and something like Audioshare but this synth doesn’t support that. I was hoping that would be possible or if anyone has any suggestion, I could be totally wrong, I’m very new to the iOS music world. Sorry for the long review, writing this hear because the developer seems like he’s great at responding here. And thank you for such an awesome synth!

Amazing flexibility, nicely balanced.

When I first bought this synth it sat in the background largely unused but it has quietly become my go to in a rather large collection of great iOS synths. For me, I find the interface very intuitive so when I’m building new patches I don’t get bogged down in trying to figure out where everything is. The sound quality is excellent but it’s the mod matrix that gives this beast so much power and flexibility! The experimenting seems endless. I have other synth that have incorporated a mod matrix but they are also populated with more features which, to me, slows down the process of creating patches. Zeeon seems to have struck the right balance of features and has been a joy to work with.If you do not like creating your own sounds, don’t worry. There are a decent amount of presets that sound terrific!

Awesome synth
Please see update below! I have been using the delightful Sunrizer synth for almost two years now, and was really looking forward to playing with Zeeon...while the sound is quite good, I’m not having luck getting the envelope generators to work properly. If this feature worked, I would find this app very useful, but for my purposes, an envelope generator really needs to work properly. Bummer! IMPORTANT UPDATE!! I heard back from the developer within hours about my “problem.” It turned out that re-starting the iPad a second time solved it. So very pleased with this app! No complaints at all now.

This is probably the best scent on iOS for just getting down and playing what’s on the screen. The knobs feel fluid, design is well thought out and many other little thoughtful details make it feel less iOS like and more synth like. Really wish there was a dark skin for it, something a little less glaring on the eyes for playing in the night like a little more Drambo brother vibe. Would pay for that!
