Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease.

Intelligent sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modeled after the inner workings of natural instruments.
Cube Synth gives you also a new method of getting randomly generated sound patches in a way you never experienced before: roll the dice! Every single try gives you a new unique sound patch, really every try, promised…

To address quibbles straight away, this app needs better in-app help to guide users through a complex and sometimes vaguely labeled interface - controlling the intricate and partly redundant envelope and modulation functions without losing grip on a sound can be difficult in Cube. Similarly, though less profoundly, the arpeggiation and sequencing controls can confound new users. Better labelling of controls in these areas would improve Cube immediately, as would more-explanatory pop-up layers responding to the help button. Maybe a secondary layer of help bubbles could be triggered after the initial simple one, offering more guidance on important functions on a given screen.

That said, the complexity of the user interface reflects a remarkable depth of functionality and control to be explored in this app. If the user patiently works through the quirks of the interface, huge rewards await in sound design. Cube allows a wide range of creation and recreation methods and gives inspiring results at the output end. These can be piercing, gritty stabs or deep, evolving, grand parts that could be whole compositions within a pad or a lead.

Oh - another complaint I have heard is with the presets. It is true, some of the presets are not all they could be. For me this is no issue (presets just serve as examples of synth functions for me), but preset players do have a good pseudorandomizer available to recombine those presets into more-pleasing patches. This being so, complaints about the presets seem to me not to have much weight.

For sound designers and for players who do not shy away from making sounds their own, Cube is an impressive piece of work. It is easy to get lost for hours trying out different approaches and playing the results. The interface issues in VirSyn products are real, and they come to roost in their more-ambitious synths. But the quality of the sound and the creative control available in Cube (and Voxel and Tera) ensure these issues are far from deal breakers.

So VirSyn has some refinement yet to do here, since Cube can be a bear - especially for new users. But there is so much that is so good in the app it stands among the slowly growing top class of synth apps in the mobile category.
