It was never so easy to create beautiful sounds and driving loops. The unique dynamic wavetable synthesis allows you to explore an unprecedented wide range of sonic territory. From acid loops, crystal clear percussions, realistic human choirs to complex musical soundscapes nothing seems impossible with only a handful parameters to tweak.

The new spectral noise generator adds a new dimension to the already huge sound universe of Addictive Synth. This generator is the first of its kind and allows for extraordinarily detailed control over the dynamic spectrum of the noisy part of sounds. Despite its complexity it's pretty easy to use and integrates naturally into the sound design philosophy of Addictive Synth.

Together with the intelligent randomizer for both sounds and arpeggios you will loose any sense of time and space while exploring unknown sonic territories.
Right from the beginning you'll understand why it's named Addictive.

Bringing new life to old gear

While more than a decade old, I just purchased this app as part of an effort to keep my ipad2/alesis iodock combo viable. I initially bought Addictive Pro, assuming that because it lists iOS 9 as the minimum required it would work, but sadly it does not (so be warned.) I already had Cube Synth Pro, by the same developer, for a few years on my iPad8 and one might expect Addictive to provide the same sonic palette. But, unless I’m missing something, Addictive appears to offer more diverse and compelling sounds and possibilities.

A reviewer below described this as "high pitched and shrill", and I have to agree. Very glassy, metallic sounding synth. If that's what you're looking for, here you go, but I found it harsh to listen to, and when you use the randomize function, it's way too easy to get too much resonance on some already shrill sound and just have piercing sonic crap coming out of your speakers.

Presets are mostly weak, and I'm not big on this form of synthesis either when it comes to making my own patches. I managed to create a nice pad on this once, but every time I come back to Addictive after a long time hoping it will be better, it's always a waste of time again.

Other reviewers will claim I don't know what I'm talking about, but I own and happily use synths like iSem, Lorentz, Animoog, Odyssei, Sunrizer, Gadget, Thor, Magellan, N-Log... They all have their good and bad points, but I'd be hard-pressed to say anything good about this one.

It is addictive

Just bought few minutes ago and started trying the presets, and they sound beautiful, I think it's a great deal, and the prize is right. I feel very happy with my purchase.
